Congress 2020
Professor Sir Charles Godfray, Director of the Oxford Martin School and Professor of Population Biology at Oxford University will anchor a plenary session at the Congress
First Keynote Speaker confirmed The Technical Programme Committee is pleased and proud to announce that Professor Sir Charles Godfray, FRS, Director of the Oxford Martin School, will anchor a plenary session, Overview of Sustainable Food – the Challenge at 2020 Vision, the 20th World Congress of Food Science and Technology in Auckland, NewZealand. Sustainability of the food supply is one of the key themes of the Congress. Charles Godfray is a population biologist with broad interests in science and the interplay of science and policy. He has spent his career at Oxford University and Imperial College in the UK and is currently Director of the Oxford Martin School and Professor of Population Biology at Oxford. He has joint UK and New Zealand citizenship and his mother grew up on a dairy farm near Kaikoura. He is looking forward to making a contribution to this event. 4
Food New Zealand
“I hugely enjoy visiting New Zealand, both because it’s a world leading centre in agricultural and applied ecological research, and also to catch up with many colleagues and family. I’m always impressed by quite how alive everyone is in New Zealand to contemporary agricultural and ecological issues, much more so than in the UK.” His research has involved experimental and theoretical studies in population and community ecology, epidemiology and evolutionary biology. Current and recent projects in his group have included studies of the aphid microbiome and how it affects the insects’ susceptibility to parasitoids and fungi, and modelling the genetic control of the mosquitoes that transmit malaria in Africa. In the past he has worked with AgResearch scientists in New Zealand on modelling the biological control of pasture pests.
Congress 2020
He is particularly interested in food security and chaired the UK Government Office of Science’s Foresight project on the Future of Food and Farming. He currently chairs the UK’s agricultural and environment (Defra) ministry’s Science Advisory Council and recently chaired a review of the UK Government’s bovine TB control strategy. At Oxford he co-directs the Wellcome-Trust funded Livestock, Environment & People (LEAP) project which seeks to explore the myriad ways that changing patterns of consumption of meat and dairy affect human health, the environment, the economy and livelihoods. Dr Jeremy Hill, Fonterra’s Chief Science & Technology Officer and also Professor of Sustainable Food Systems at Riddet Institute, says, “We are delighted to have someone with Sir Charles Godfray’s knowledge and expertise present the opening talk of the session and join our panel discussion. Sir Charles will bring a broad international context to the conversation as we explore the challenges and opportunities of providing the nutrients required by the growing global population.”
Looking ahead Watch these pages for news as the work continues to present a memorable World Congress continues. By the close of abstract submissions on 31st October, the Technical Programme Committee was gratified to have received many more abstracts that expected from all corners of the world and are now engaged in the enormous task of assessing these and allocating suitable papers to sessions. Author notification is scheduled for early December and the final programme will be posted on the IUFoST 2020 website, www.iufost2020.com by 28 February 2020.
What is the Oxford Martin School? Since 2005, the Oxford Martin School has aimed to sow the seeds of change, acting as a ‘kickstarter’ for experimental and novel research. More than a decade on, many of these programmes have matured into independently funded institutes, allowing the school's researchers to focus on new collaborations, experimentation and new ideas. The School’s academics work across more than 30 solutions-focused, pioneering research programmes that cut across disciplines to find solutions to the world's most urgent challenges. From renewable energy to ocean sustainability, and from the future of work to tackling inequality, they foster ground-breaking collaborations between researchers working at the frontiers of knowledge. The unifying theme is that the research must be of the highest academic calibre, tackle issues of global significance, and could not have been undertaken without our support. Underpinning all research is the need to translate academic excellence into real-world impact, from innovations in science, medicine and technology, through to expert advice and policy recommendations.

EDITORIAL EDITORIAL Universities of Tomorrow Where do food technologists come from? From universities in the main. Ours, mostly from New Zealand universities, but some come from the Philippines or Thailand or the UK or elsewhere. But our universities are in trouble. Around the world they seem to be in a similar mess. University administrations spend more and more on analysts to understand why they are so expensive and unproductive. Teaching departments are progressively starved of personnel. Teachers are measured more and more by research performance, yet research funding is isolated more and more into specialist research centres. Teachers and researchers are being combed either side of a parting. Progressively, retiring teachers are being replaced by cheaper, short-term, contract staff. Digital techniques are being treated as an end in themselves rather than an educational tool. And courses are being compressed into one-size-fits-all, generic lumps in defiance of the increasing heterogeneity of new students. This pattern seems ubiquitous. Governments are increasingly sceptical of the value they get for their money. So what is the answer?
Richard Archer, President, NZIFST
This is almost exactly how the car manufacturing industry was in the 1970s. They had a large number of separate companies making a large number of models. Traditional European and American strength was challenged from Japan and Korea. Quality was so-so and innovation patchy. Cars were neither cheap nor efficient. Workers were striking and companies losing money. Then what happened? If today’s vice-Chancellors had sat round the collective Automotive Board table then, this is what they would have done: • Remained as independent competitors • Reduced the number of models and colours so they could shed staff to reduce cost • Ignored their customers' desire for diverse models • Used emerging automation tools to standardise, reducing flexibility • Progressively lost revenue and ultimately failed And here is what they actually did: • Amalgamated and cooperated so that they could each make fewer components • Reduced the total number of components and sub-assemblies • Increased the numbers of models - they developed mass customisation by mix and match • Adopted new automation tools to increase flexibility • Offered new products rapidly to meet rapidly changing markets
The car industry now offers more models, of higher quality at lower real cost than ever before – and is profitable. Today’s globalised, flexible and responsive car industry is a huge success. The car industry adopted principles such as “Lean”: they sought out waste and got rid of it. To find the true source of waste they empowered individual workers and low-level managers. They gave them data, information and simple analytical tools. They did not merely sit in a remote office and attempt to model reality from a position of ignorance. Yes, university education and car manufacture are very different. But they are both complex organisations bound by the same laws of psychology and economics. I strongly believe an intelligent university could learn much from the car industry. Even now, very few universities worldwide can afford the 20-plus specialist staff that you need to teach comprehensive food technology well. We should cooperate and joint-venture so that each university provides a lead in only 4 or 5 specialist areas and prepares top grade curriculum material for the others in the club. Increase the number of degree offerings but decrease the number of teaching modules you use. Be flexible as needs change and watch the future. It is not hard to find waste in a university: the most valuable item is academic time –“Lean” should be easy. Don’t save printer ink or paper or air miles if it costs you more in academic hours. This is what the car industry discovered so crisply – ironically with the help of some smart universities! Richard Archer, FNZIFST, President

IN-BRIEF
In-Brief In-brief is Food New Zealand’s pick of the news stories about NZIFST members, about companies with relationships with NZIFST plus items that catch our interest. Whitestone’s Farmhouse wins Bronze Whitestone Cheese Co. received a coveted Bronze award for its Farmhouse cheese, a pressed white mould semi-soft cheese, at the World Cheese Awards, 2019. This was Whitestone’s first and original cheese that launched the company in 1987. Farmhouse is a pressed cheese with a white mould rind, unusual in the world of cheese. With entries representing 42 nations from six continents at the World Cheese Awards this year, Whitestone Cheese has gained an internationally recognised seal of approval from a truly global cheese event. Visiting Italy for the very first time, the competition formed part of Bergamo’s annual FORME festival, taking place alongside the brand new international dairy trade show, B2Cheese. Simon Berry, Whitestone Managing Director is very proud. “To achieve an international bronze is fantastic recognition for our original cheese that has gone unchanged since the late 80s and also for our founding team and their pioneering development back in 1987. We will enjoy celebrating this success with all team over the coming weeks.”
Exploring what Kiwis eat A new partnership aimed at exploring what Kiwis eat and why will be undertaken in a partnership with Bayer New Zealand and the New Zealand Nutrition Foundation (NZNF). Coined as the Bayer Food Focus Project, the partnership brings together Bayer and the New Zealand Nutrition Foundation (NZNF) with expert help from the Foundation’s Board members, Elaine Rush, Scientific Director and Emeritus Professor of Nutrition at Auckland University of Technology (AUT), and Niki Bezzant, nutrition writer and commentator. The project will consist of two key parts: the use of a new innovative technology, the Veggie Meter, to establish a benchmark of Kiwis’ vegetable and fruit consumption; and an online questionnaire to understand which foods New Zealanders are commonly consuming. The Veggie Meter, originally developed in the US, measures participants’ levels of beta-carotene through a fingertip reading device. The technology accurately and painlessly measures whether people are getting enough beta-carotene from plants to be considered healthy. This will be the first study in Australasia to use the Veggie Meter technology. “Much of New Zealand's nutrition data is out of date. This creates
challenges for researchers, the food industry and policymakers when looking into what needs to be done to improve the food system and health outcomes for Kiwis,” says Professor Elaine Rush. “We want to find out what the average level of plant Vitamin A is among our population as this will give us a benchmark against the recommended intake, as it’s reported that only four out of ten New Zealand adults consume the existing recommendation of five plus a day.” Although the Bayer Food Focus project does not profess to be an update on the decade old Adult Nutrition Survey carried out by the Ministry of Health in 2008-09, it does hope to plug some of the gaps felt by the industry. “We should uncover some interesting findings that shed light on our dietary habits as a nation, and perhaps, make people stop and think about their own food consumption,” says Niki Bezzant. Having access to a valid measure of the quality of foods eaten and gaining up-to-date insights into what and why certain foods are being consumed over others, can help us better address these issues and find actionable solutions to make health and wellbeing a priority for all,” concludes Sarah Hanrahan, Chief Executive Officer of the NZNF.

10 Key Trends in Food, Nutrition and Health 2020 Plants still hot but meat’s not off the menu – health-conscious consumers want it all People love plants. With their “naturally functional” halo, consumers of all ages want to eat more of them – and in more convenient forms. From cauliflower pizza to beetroot bread, plant-based is a trend that’s growing for the long term. But people also love meat. Despite vocal attacks on meat’s health and sustainability credentials, which made it look as if the meat category was set for long-term decline, consumption has increased in both the US and in Europe in recent years. “Consumers’ perception of meat as a tasty and high-quality protein is driving the reinvention of meat and will secure its permanent place on the plate – and as a snack,” says Julian Mellentin, a consultant to the food and beverage industry and author of the report 10 Key Trends in Food, Nutrition and Health 2020. This annual trend analysis identifies – for the first time – meat as a growth opportunity, alongside plantbased.
the influence of other key consumer trends identified in the report, including protein, lower-carb and the rebirth of fat. Consuming fewer carbs – which by definition means eating more fat and/or protein, often in the form of meat – is growing in popularity, fuelled by diet patterns such as keto. And low-carb eating is now legitimised by science. Fear of the ultimate ‘bad carb’ – sugar – is now mainstream. A massive 80% of US consumers say they are limiting or avoiding sugar in their diets, and there are similar levels of concern in Europe and South America. It's a reflection of the fragmentation of consumer beliefs that, alongside a growing demand for low-carb products, honest indulgence is also a big growth driver: “In the midst of the focus on health and nutrition, let's not forget that most people buy bakery products for pure pleasure,” adds Mellentin. “Natural ingredients, provenance and great taste all matter more than nutrition.”
The 10 Key Trends identified in the report are: 1. Digestive Wellness 2. Good Carbs, Bad Carbs 3. Plant-based
“People want plants, but we’re not all turning into vegans,” says Mellentin. “In a world where consumers hold fragmented beliefs, there’s room for both plants and meat.”
4. Protein
“With plant-based getting all the attention, and meat under attack, creative meat producers are taking steps to reinvent their category, for example with sustainability, provenance and convenience,” he adds. For example, US sales of meat snacks grew 6.7% in 2019 to $4.5 billion (IRI).
7. Meat Reimagined
And Nielsen data shows that meat brands that communicate about provenance, sustainability and animal welfare are growing fast and earning premium prices. US sales of meat with health or environmental claims are growing rapidly, led by “organic” up 13.1% and “grass-fed” up 12.2%.
And there are four “Mega Trends” that are a must-do for all companies in all categories:
It's a transformation that will be welcomed by consumers, who love to hear that something they enjoy is also good for them – as happened with red wine and chocolate. And they’re particularly receptive right now to positive messages about meat, says Mellentin, thanks to

Engineering the future of safe food and beverage production Engineering doesn’t necessarily spring to mind when you first think about food, beverage or dairy production, but for the team of engineering experts at AsureQuality providing services to the dairy, food and beverage industries, it’s what gets them up in the morning. AsureQuality engineers work with customers as independent assessors and evaluators: “We walk the whole journey with our customers - from when they first start to even think about building a manufacturing plant and register their Risk Management Plan, right through every single step of the production process,” says Samuel Brooks, Business Manager Food and Dairy. “We provide the necessary independence, from a regulatory point of view, that our customers require, along with a huge depth and breadth of engineering expertise on tap, which has enormous benefits for our customers.” The engineering team are hyper-aware that their primary role is to help customers protect food safety and they take this very seriously: “Any time we work with a customer, our ultimate objective is to form a partnership on the ground floor, so that we never have to be the ambulance at the bottom of the cliff. That is always going to be a risk when you are dealing with food safety. At the end of the day its about having us involved right from the start. Getting it right up-front is worth every cent of investment - the cost further down the line
can be enormous to a business. We work hard to help customers avoid that.” Recent projects undertaken have been diverse and include heat treatment assessments and audits, product testing, gap analyses and premise evaluation for a wide range of customers and covering everything from dairy, fruit juice, plant-based beverages, wine and beer, to cooking stocks, soups and other liquid products. While a significant part of their work is in the dairy industry, due to growing demand for convenience foods and products with a good shelf life, they now work with many customers in the food and beverage sector, where their expertise in UHT and heat treatment applications can deliver real value. In recent examples they were able help a fast-growing business to increase their production levels, and another customer to increase product shelf life, all while maintaining food safety and product integrity. “We are here precisely to make things as efficient, seamless and pain-free as possible for customers so that they can get on with what they excel at – taking the very best that our country has to offer to both domestic and international markets.” For more information: www.asurequality.com

IN-BRIEF
In discussions of body weight and obesity, milk and other dairy products can be targeted for their apparent high sugar content, leading many to mistakenly believe that dairy should be limited to avoid weight gain through consumption of excess sugar. As part of the 2019 IDF (International Dairy Federation) World Dairy Summit, several highlevel international speakers addressed the sugar question, discussing the latest science on dairy and sugar in our diets. Milk, plain yogurt, and other unsweetened dairy products contain the naturally occurring sugar lactose. Unlike added sugars, which contribute plenty of calories but no nutritional value, lactose in dairy is part of a nutrient-dense package, providing an abundant supply of high-quality protein, calcium, phosphorus, potassium, iodine, and vitamins B2 and B12.
The sessions concluded that there is no evidence that sugars naturally present in milk and dairy foods (lactose and galactose) have adverse effects on health. In fact, a growing body of research indicates that dairy may play a protective role against certain non-communicable diseases, including type 2 diabetes. Nutritionists and scientists have increasingly begun to consider that the effects of milk and dairy foods on health extend beyond the benefits of the individual nutrients they contain. In a process known as the Dairy Matrix, the different structures and textures of dairy products have an impact on how these nutrients are absorbed in the body. This could have important positive impacts for health. “Scientists investigating the health effects of the Dairy Matrix have already noted its positive impact on bone health and some noncommunicable diseases. Going forward, greater understanding of dairy food structure and nutrient absorption could pave the way to developing innovative dairy products that improve the nutritional status. It’s imperative that when discussing dairy within diets, a ‘whole food’ rather than an ‘isolated nutrients’ approach is taken,” says Dr David Everett, Chair of the IDF Standing Committee on Dairy Science and Technology and Leader of the IDF Action Team on the Microstructure of Dairy Products 10

Dr Michel Donat, Team Leader, IDF Action Team on Flavoured Dairy says, “The global obesity crisis is something that the dairy sector takes very seriously. However, the discussions at the IDF World Dairy Summit show it is wrong to assume that the natural sugars in milk and dairy products are the same as other added sugars. The dairy sector needs to help consumers to become educated on the sources of sugar in their diet and learn to strike the right balance between nutrients and sugar intake.”

Furthermore, studies have clearly indicated a differential role for foods that are inherently nutritious such as milk and yogurt. When children and adolescents consume dairy products such as flavoured milk and yogurts, the quality of their diet improves, and in the case of studies looking at the impact on weight, no adverse effects were found.
The IDF is the leading source of scientific and technical expertise for all stakeholders of the dairy chain. Since 1903, IDF has provided a mechanism for the dairy sector to reach global consensus on how to help feed the world with safe and sustainable dairy products. A recognised international authority in the development of sciencebased standards for the dairy sector, IDF has an important role to play in ensuring the right policies, standards, practices and regulations are in place to ensure the world’s dairy products are safe and sustainable.

Five students will undertake R&D internships with Comvita this summer. Comvita is one of 70 F&B companies that have secured R&D Experience Grants from Callaghan Innovation
F&B companies set for major R&D boost this summer More than 120 university students will work on research and development (R&D) projects in F&B companies around the country over the next couple of months. Projects will span everything from identifying potential business efficiencies using data analytics to exploring the nutritional value of crickets. The nationwide boost to R&D skills and capacity is being supported by Callaghan Innovation’s R&D Experience Grants, which provide funding for a science, technology, engineering, design or business student – or new graduate – to work on a company’s R&D project for ten weeks at the end of the university year. Food & Beverage Business Innovation Advisor, Braden Loveridge says applications for the R&D Experience Grants are growing each year as companies realise the value of the summer internships. “These internships give companies the opportunity to bring fresh skills and talent into their business, and to dedicate extra resource to existing R&D projects that they’re hoping to progress more quickly, and it’s all funded by the grant,” says Loveridge. “In some businesses the student interns will be working on brand new R&D projects, because the company has an area of research or potential opportunity that they’ve been wanting to explore but they haven’t had the time or capacity.” “For students, these internships provide a really unique opportunity to gain R&D experience and to understand how exciting and innovative the sector is – that’s a real positive for everyone working in food and beverage.” More than 70 F&B companies from across New Zealand, including businesses in Tauranga, Auckland, Canterbury, Nelson and the Waikato, have secured support for 125 student internships – a massive increase on the 21 companies who secured funding for 46 internships last year. In total more than 520 companies around New Zealand have secured 2019/2020 R&D Experience Grants and more than 1300 students will work on R&D projects – up from 660 internships in 2018/2019. Companies applying for this year’s R&D Experience Grants included first-time applicants and businesses that have already built the summer internships into their annual planning and are using them as a valuable tool to find news skills and talent. “We had five student internships supported by Callaghan Innovation’s R&D Experience Grants last summer and we’re being joined by another five students this year,” says Comvita’s Head of Research, Jackie Evans. “Having the support for these internships gives our R&D capacity a real boost and we’ve been really impressed by the calibre of the students who have worked with us.” This year’s interns, who will work at Comvita’s Paengaroa HQ in the Bay of Plenty, include students who are studying data science
and computing, engineering, pharmacy and food technology, from Waikato, Canterbury, Auckland and Massey University. “We’re really excited about the breadth of skills these students are bringing,” says Dr Evans. “This year the projects will explore how we can use data analytics to unlock efficiencies in our business, researching the gut health benefits of Manuka honey and the use of technology to preserve the unique bioactive properties of our Manuka honey during processing.” Dr Evans says the internships give the students valuable real-world experience and opportunities, and are a great way to introduce new talent into the business. “We had a postgraduate student join us as an intern, with the support of an R&D Career Grant from Callaghan Innovation, and she has stayed on with the business.” BWL from the Wairarapa is one of the F&B companies who applied for the R&D Experience Grant for the first time this year and their student intern will be helping to build the case for crickets as a food source. "We're excited to be working with a food technology student over the summer break to take the first steps in our research to identify and extract some of the health-promoting compounds in crickets,” says BWL Future Foods Manager, John Hart. “Early overseas research has delivered some promising results about the abilities of crickets to improve gut health – and we’re looking forward to seeing what we can achieve through our Callaghan Grant over the next few months.” Callaghan Innovation’s Group Manager for Food & Beverage, Katy Bluett says the R&D Experience Grants are just one of the ways her team is able to provide support to F&B companies wanting to invest more in R&D or identify new opportunities to innovate. “Our R&D Career Grant and Fellowship Grants are another great way to advance R&D projects and to bring fresh talent into F&B business.

Strategy, Summit and Awards
What’s new at New Zealand Food Safety? We’re pleased to share details about our upcoming Summit, and an update on our Strategy and sponsored Awards.
New Zealand Food Safety Strategy A consultation was held by the New Zealand Food Safety team to test our draft strategy with food businesses, academics, partners, iwi, industry representatives and consumers. We received 307 submissions, with 62% of these from consumers. Our online survey was a success with 83% of submitters using this as their vehicle for providing their thoughts on the draft strategy. We are now analysing the submissions to discover what else should be included in the strategy and what needs to be amended to make sure the organisation is focused on the future and is clear about how we will continue to deliver for New Zealand consumers, food businesses, and our trading partners. The final strategy will be launched at the Food Safety Summit on 10 December in Auckland.

FOOD SAFETY
A New FSANZ Act Glen Neal, General Manager (Food Standards), FSANZ, New Zealand
Friday 15 November will go down as a red-letter day for the TransTasman food regulatory system. The 10 Ministers (8 State/Territory, 1 Australian Commonwealth and the NZ Minister for Food Safety) agreed to an ambitious reform package for a system regarded as performing well but in need of a freshen-up. The centrepiece of this reform will be an assessment of the range of functions performed by FSANZ, including a review of the empowering statute, the FSANZ Act. The Act sets out our purpose, functions and the matters we must have regard to when setting standards. I am sure everyone will agree the first priority will remain the protection of public health and safety. Food safety isn’t that sexy these days. It’s pretty much taken for granted. This is a generally a good thing as consumers can be confident that the safety of their food is underpinned by science-based rules.
FSANZ is a binary operator in an increasing tertiary environment. We have one major lever to pull - to adjust the Code or not. Whether we are talking enzymatic processing aids or an overhaul of infant formula standards, we have to follow similar processes. I am sure Ministers have better things to do than turn their minds to whether or not pullulanase should be allowed to be used in starch preparations. A more proportionate approach to the work we do is long overdue. Spending less time on, and having slicker processes for, enzymatic processing aids is probably sound. As is being able to spend more time on more complex and inherently riskier approvals also makes sense. Novel foods and health claims are other areas where, with additional functionality we can better protect consumers, provide more certainty for regulators and better support food innovation.
However, a few issues have arisen that perhaps weren’t contemplated when the Act was first considered and then conceived in 1991.
The Act is highly prescriptive and more than a little clunky in terms of its operation and we’d welcome a more permissive, enabling riskproportionate-approach to our work.
Perhaps an obvious example is the rise of the obesity epidemic and the accompanying sequelae. Sure the role of nutrition and its impact on public health is no recent phenomenon but the role that FSANZ can and should play in tackling this critical problem is an issue that needs to be made clear.
The FSANZ Act review will be run by the Australian Department of Health as they are the owner of this policy. Rest assured we have a range of ideas in the chute and will work closely with the Department throughout. Keep an eye out for opportunities to have your say throughout 2020 - and possibly beyond.
Food safety isn’t that sexy these days. It’s pretty much taken for granted.

Introduction Milk and dairy products are an important source of nutrition. Besides cow milk, which contributes the most volume produced globally and in New Zealand, milks from other animal species such as goats and sheep attract premiums due to their superior nutritional attributes and health benefits (e.g. increased digestibility and low allergenicity) [1, 2]. Goat and sheep milk and their derived dairy products command a higher price than cow milk-based products. There have been cases wherein cheaper cow milk was added into a more expensive milk/ product without a proper declaration, known as “adulteration” [3]. Reliable methods are therefore required to verify milk origin to ensure the authenticity of the high-value dairy products to protect the rights of consumers and the value of New Zealand exports of these high-value products. Milk from different species contains different proportions and concentration of caseins and whey proteins [4]. Besides the differences in protein concentrations, milk proteins from different species are known to have minor differences in their primary structures [5]. These are caused through amino acid substitutions in various parts of the protein, which may mean that milk proteins from different species could contain unique peptides and protein variants, leading to specific chromatogram protein profiles and molecular masses, that could be used to identify species adulteration of milk products. To date, several analytical methods have been used for milk species differentiation and quantification including isoelectric focusing, immunological, electrophoretic and DNA-based techniques [3]. However, these methods are either laborious or unable to identify milk species adulteration in dairy products, partly due to the modifications of milk components obtained during processing of dairy products. In this study, both reversed phase-high pressure liquid chromatography (RP-HPLC) and nano-liquid chromatography-tandem mass spectrometry (nLC-MS) based methods were used to investigate milk protein chromatogram profiles and unique peptides, respectively. RP-HPLC provides the chromatogram protein profile fingerprints of milk from different species in a relatively short time and with simple sample preparation, while the analysis of peptides with nLC-MS allows identification of specific unique peptides with or without modifications.
The quantification of the levels of cow milk added in a milk mixture with the intensity of the unique peptides was also determined. The methods established and the results obtained in this study provide useful tools for investigating the differences in milk proteins from different species.
Methods Cow, goat and sheep milk samples were collected from local farms in New Zealand. Milk chromatogram protein profiles were obtained using RP-HPLC with a C8 column and UV detection. Unique peptides between milk proteins from the three different species were determined in silico and experimentally for sheep and cow milk using nLC-MS with a C18 nano column. Two peptides from β-lactoglobulin (β-Lg) were found to be suitable markers for cow and sheep milk. Mixtures of milk containing 0, 1, 5, 10, 30 and 50% cow milk in sheep milk were used for the determination of the correlation between the proportions of cow milk in milk mixtures with the intensity of the unique peptides. Milk samples were prepared for nLC-MS analysis by separating into whey and casein; urea extraction of the proteins; methanol-chloroform purification; followed by reduction, alkylation and digestion with trypsin. Samples were identified using Mascot and the Swissprot Bos Taurus and Ovis aries databases. The correlation between cow milk concentration in mixtures of cow-sheep milk and the intensity of unique peptides was established by plotting the sum of the intensity of all unique peptides against the percentage of cow milk.
Research Findings Cow, goat and sheep milks generate distinctive RP-HPLC chromatogram protein profiles Milks from cow, goat and sheep generated RP-HPLC chromatogram protein profiles with distinctive features (Figure 1). As expected, cow milk exhibits the major protein peaks of α, β and κ-caseins (α, β, κ-CN) and whey proteins (α-lactalbumin (α-La) and β-Lg) (Figure 1A). The RP-HPLC profiles obtained from the goat and sheep milks are distinctively different from that of cow milk, in terms of peak numbers December 2019/January 2020

and occurrence/shape (Figure 1B-C). Nine major peaks, which correspond to caseins and whey proteins, were identified for goat and sheep milk. β-CN in cow milk appeared as two connecting peaks (Figure 1A), corresponding to the two major variants, β-CN A1 and A2. Only one corresponding β-CN peak (peak 8) was observed in goat or sheep milk (Figure 1 B -C). Our previous study showed that only one β-CN variant was found in sheep milk, which has the amino acid proline at the position 67 (P67), homologous to β-CN A2 in cow milk [6]. Peaks 5 and 6 in goat milk (Figure 1 B), which likely correspond to αs1CN, were considerably lower in intensity than in cow and sheep milk, consistent with the lower αs1-CN concentration reported for goat milk [7]. Three protein peaks, namely α-La, β-Lg A and β-Lg B, were found in the whey protein regions
Figure 2. Protein alignment between cow, goat and sheep β-Lg (without signal peptide). Regions containing unique peptides are highlighted in green (cow), blue (sheep) and purple (goat) (retention time 17 min onwards) of cow milk, but only one main peak (peak 9) was identified in this region in the protein profiles of goat and sheep milk. In the region between αs1-CN and β-CN, goat milk featured one additional peak (peak 7) (Figure 1B) while sheep milk featured two small additional peaks (peaks 6 and 7) not found in cow milk (Figure 1C). They could be α-La [8, 9] or other minor whey proteins. Due to the lack of standards of individual proteins from goat and sheep, the protein identities will need to be further confirmed using mass spectrometry analysis of individual peaks. The above findings demonstrate that distinctive protein profiles from cow, goat and sheep milk can be generated using RP-HPLC, which can be used to identify milks from these species. Cow and sheep milk proteins contain unique peptides as predicted in silico and confirmed using nLC-MS

Research
One approach to detect and quantify species adulteration in milk is to measure the abundance of molecules unique to that specie. Because of the primary sequence differences in cow, goat and sheep milk proteins, unique peptides can be found to be associated only to the milk of one origin after tryptic digestion (a step used in preparing samples for nLC-MS). This can be determined initially in silico by aligning the same protein from sheep, goat and cow (Figure 2). Two peptides in bovine β-Lg are expected to differ from goat and sheep milk: TPEVDDEALEK125-135 (amino acids (AA) 125-135 of the 162 AA-long protein) and LSFNPTQLEEQCHI149-162 (amino acids unique to bovine β-Lg are shown in bold and underlined). To confirm that these peptides can be experimentally observed, cow and sheep milk samples were analysed by nLC-MS. Figure 3 shows the mass spectra between the sheep and cow peptides for both unique peptides examined. The amino acid substitutions were found in different sized peptides due to non-specific cleavage and peptide modifications. The correlation between the intensity of the unique cow peptides and the level of milk adulteration was next investigated using nLC-MS for cow-sheep milk mixtures with concentrations of cow milk in sheep milk ranging from 0 to 50%. The results are presented in Figure 4. The best correlation was obtained with the peptide LSFNPTQLEEQCHI149-162 with a R2 value of 0.974. This peptide, however, was not observed consistently in the sheep-cow milk mixtures containing 1% cow milk, indicating the method may not be suitable if cow milk is present at less than 1% in sheep milk, which is most likely to be a case of contamination rather than deliberate adulteration. As the corresponding peptide in sheep and goat milk is identical, this peptide could also be used as a suitable marker to detect adulteration of cow milk in either sheep or goat milk. The other unique bovine peptide examined was TPEVDDEALEK125-135. The abundance of this peptide showed good correlation (R2= 0.9997) to cow milk concentration in mixtures ranging from 1% up to 30% cow milk in sheep milk.

Milk proteins from different species (cow, goat and sheep) generated distinct RP-HPLC protein profiles and contained peptides unique to either cow milk or sheep and goat milk that can be detected by nLCMS. Two peptides were identified from β-Lg that can be used to confirm cow (TPEVDDEALEK125-135 and LSFNPTQLEEQCHI149-162) or sheep milk (TPEVDNEALEK125-135 and LAFNPTQLEGQCHV149-162). The developed RP-HPLC method could be used as a rapid scanning tool to profile protein fingerprints of milk from different species for milk differentiation and identification. The nLC-MS method could be used to detect adulteration and quantify the level of adulteration down to a limit of 1%.

FIET
FIET Project: Creamed Pomace – a smooth-textured dietary fibre product from apple pomace Authors, Richard Archer, Marzieh Eblaghi, Florencia M. Yedro, Erin O’Donoghue, Lee Huffman and John Bronlund We first reported on the Pomace Creaming FIET project in the June/July 2018 issue. Here is an update – we are in the commercialisation phase now.
Introduction “Eat more fibre” remains a powerful message. It’s not surprising, since for most of us, fibre can reduce the risk of coronary heart disease, stroke, hypertension, diabetes, obesity, and gastrointestinal diseases [1]. And “give me a good fibre ingredient” also seems to be a powerful message within the industry. Food manufacturers want fibre lighting up the label, but they also want an ingredient to be affordable and to perform. A baker may want water-holding capacity, a juice-maker may want a stable dispersion. Most want a smooth texture without the sharp edges that apple tissue can carry. We started in FIET, four years ago, to look for a simple, robust process to take pomace such as from apple through to a stable food ingredient for sale. Early discussions with potential end users steered us toward a smooth, almost fat-mimetic texture and toward water-holding capacity in baked goods. And of course we wanted to deliver fibre both soluble and insoluble. New Zealand’s 10,000 – 15,000 MT of apple pomace made it the prime target to start with.
Scope of research Under the FIET programme, our research team from Massey University and Plant & Food Research has developed a very effective process and resulting product with a creamy texture and neutral flavour. It comes in powder form and is nicely hot-water soluble. We have run the process successfully at pilot scale with the heat treatment in batch mode and now are ready to run the process continuously. We have done one trial to prove that we can make a light fawn coloured product (not dark brown which we can also achieve by paying little heed to enzymatic browning). And we did one trial which proved the powdered product to be nice and dispersible in hot water. Part of the work was to investigate how much wet milling the product needs in order to be smooth on the mouth and what the impact of pectin chain length is. This showed, as we expected, that finer particles (within reason, because round, unbroken whole cells are good) and longer pectin chains, give a smoother result – or so say the 84 volunteer taste panellists.
Process The process is relatively simple, provided you know how. We need to catch the pomace just as soon as it is generated and strip out stalks, pips and labels. We mill it just enough to make it pumpable and then give it an in-line heat treatment. By tweaking temperature and time, we have a flexible and versatile process, able to be tuned to various raw materials and end products. 26

The research team, l-r, Richard Archer, John Bronlund, Florencia Yedro, Marzieh Eblaghi, Erin O’Donoghue and Lee Huffman The hydrothermal treatment has several jobs: killing microorganisms, deactivating enzymes, solubilising pectins, softening the cell wall and “ungluing” cells from each other. But too much heat for too long can have undesirable effects on the appearance, flavour, colour, and nutritional value. The sweet spot is not large and depends on the product desired. After heat treatment we can concentrate the pomace a little by flash evaporation and then dry it to a powder. We proved all this process - one step at a time – in the lab. That gave us the kinetics of each of the desirable and undesirable reactions. We then scaled it up about 100 fold and proved to ourselves at pilot scale that the kinetics are right and that each step works. We think we know the process well enough for it to be largely a matter of engineering from now on.
Commercialisation The engineering and technical company, Aurecon and particularly Aurecon’s Brent Dingle, are taking on the process to provide full-scale plants to juicing companies with a pomace problem and potential ingredient markets. Brent presented the process to the assembled food engineers of the world at ICEF13 Melbourne in September. But before supplying to the world, we have several New Zealand juicing companies (not all New Zealand owned I must admit) keen to see a plant built and to understand its economics. The next step is to feed the continuous pilot plant enough pomace to generate enough powdered product for applications work. One key application is to use the creamed pomace as a drying aid and encapsulant for spray drying juice or honey - this is being developed
FIET
One option: pilot concentrating creamed pomace to a paste ... ... and another option: pilot drying creamed pomace for milling to a powder
under FIET Project 8. The buying public is getting nervous about â&#x20AC;&#x153;maltodextrinâ&#x20AC;? (which surely must be a synthetic and nasty additive) as a drying aid for sticky materials. We are backing creamed pomace as a natural, label-friendly alternative.
Future perspective The process is largely optimised, at least at small scale. We need now to generate some engineering data to support design and building of the first units. And we need to move on to applications work to support the first purchaser of a plant.

OILS & FATS Phthalates GOED has learned that the State Administration for Market Regulation (SAMR) in China plans to implement a new regulation designed to reduce dietary exposure to phthalate esters. According to the Announcement, limits for three phthalates in fats and oils are being proposed, including: DEHP (1.5 mg/kg), DINP (9 mg/kg) and DBP (0.3 mg/kg). The fats and oils affected include edible oil products and animal fats, so it is thought that fish oil will be subject to the new limits. GOED has summarised information obtained from members on the levels of dioxins and PCBs, as well as of the process contaminants 3-MCPD and glycidyl-esters, in EPA/DHA omega-3 oils (details were presented at the recent member meeting at SupplySide West). GOED received the original data from 18 members; anonymous data can be viewed for dioxins and PCBs and MCPD. https://goedomega3.com/
Gut health, saturated fat and cardiovascular disease Studies indicate that dietary fat quantity and quality influence the gut microbiota composition which may as a consequence impact metabolic health. This systematic review aims to summarise the results of available studies in humans on dietary fat intake (quantity and quality), the intestinal microbiota composition and related cardiometabolic health outcomes. Individuals who consume a typical Mediterranean diet are less prone to anomalies in gastrointestinal microbiota, a growing body of evidence suggests. Now, researchers at Manchester Metropolitan University (MMU), in
the United Kingdom, are working to add to this collective knowledge. Haleh Moravej, a senior lecturer in nutritional science at MMU, and a team of students at the university have launched the MetMUnch initiative in order to do so. “Scientists have known for a long time that there is a connection between our gut and brain via nerves, but now we have gut bacteria entering the arena,” Moravej told Olive Oil Times. “They communicate with the brain in three different ways,” she added, “They send signals up the vagus nerve directly to the brain, influence immune cells in the gut that produce chemicals that travel in the blood, and some can get through the blood-brain barrier to the brain.” Clinical Nutrition Volume 38, Issue 6, December 2019, Pages 2504-2520
USFDA looks at Olive Oil Standards At last one of the biggest global markets for Extra Virgin olive oil is re-examining regulated standards. It is widely accepted that the IOC standards are outdated and have not kept up with increasing consumer awareness of quality and measures to eliminate fraudulent behaviour. AOOPA, which represent California, Florida, Georgia and Texas olive growers, and Deoleo are asking the FDA to create standards of identity across the various grades of olive oil. The petition also includes other tests to determine freshness and shelf life, and outlines “modern advancements in analytical testing methodologies.” The Australians, after a great deal of detailed and pragmatic research, came up with their standard which has now been in place for several years. The large supermarket chains have embraced the standard and overall quality in Australia is now much improved over previous years.

MIA
Meat Industry Association News Ali Spencer Once the stuff of science-fiction, the future is coming to a meat industry workplace near you in the not-toodistant future. The Meat Industry Association (MIA)’s Kaylene Larking spent time last month strapped into an Exoskeleton, new wearable technology being trialled to reduce injuries in meat processing. It’s all part of Larking’s day job as research partnerships manager for the trade organisation which she has run Kaylene Larking for MIA Innovation Ltd since 2015. She helps lead the MIA’s continual quest for new science and technology to invest in to improve products, food safety and the health and safety of the sector and the jobs of its people. “It’s really neat to see some brand-new emerging technology, see the potential of it from my desk and watch it come to life when showing it to people,” says Larking. A roadshow was organised in November for meat industry people to learn more and try on the new technology. This was led by MIA, but primarily funded by WorkSafe, with which the trade association signed a partnership agreement in 2018. The Exoskeleton, from US company SuitX, is designed to provide strength and support for mechanical and repetitive tasks, reducing injuries and increasing productivity. It has potential for being especially useful during periods of repetitive carton lifting and stacking at height in the meat processing works. Two beta-prototype models of the spring-loaded non-mechanical device were shown: one worn like a backpack to assist shoulder movements; the other a version for the back that is worn like a harness. Both fit a wide range of sizes and can be used independently or together as the job requires. There are no cables to have to contend with, it does not require batteries, can be donned and doffed easily and the worker will be able to move naturally, but with extra strength and safety. The robotic exoskeleton originated in the US medical world following its invention by a researcher looking for a way to help his paraplegic friend to move again. After expanding into use by the military, it is now entering industrial processing where it is finding a niche. Studies have shown the units reduce muscle activity by 45% during tasks. Along with AsureQuality, the MIA has been following the technology for some time and had been liaising with Australia’s Meat & Livestock Association (MLA) on a number of industry-good projects, where it makes sense for them to work together, Larking relates. “MLA had done a lot of the groundwork, establishing that SuitX was the most reliable company to work with,” she says. After its members saw the technology at the IFFA meat processing trade show in Germany last year, MIA invited the Australian agent, Biosymm, to New Zealand. It was also helpful that Biosymm are physiotherapists with a focus on injury prevention in the workplace, so they understand the stresses bodies are under during strenuous activity and see SuitX as a valuable tool to reduce the risk of injury. 30

Larking trying out the shoulder unit. It was: “Quite remarkable,” she says
Enthusiastic response Larking was thrilled at the interested and enthusiastic turnout to the seminars, which saw about 110 representatives from MIA’s member companies and other invited guests attending the six sessions, held from Hamilton through to Invercargill. “The awesome thing was that, for anyone who wasn’t quite sure of the technology, as soon as they tried it on they could see what the benefits were going to be.” For many, it was “a lightbox moment,” she says. They could see the Exoskeleton is a handy tool allowing the unit to take the strain of lifting things. “It’s designed to make you use your muscles properly. You can’t lift more weight but it gives you support and assistance for the dangerous aspects of the job.” More work is required to customise the Exoskeleton for use in a meat processing environment, especially the hygiene areas, and also to determine how it might work with other protective gear used by workers. “It’s not perfect yet, because it’s still in development, but Biosymm will provide a whole heap of support to help us customise the suits to our requirements,” says Larking. “Where a company might have been thinking you need a robot to do a job, we can now power people up to help them so they don’t get injured. That’s wonderful.” While v3 of the Exoskeleton can be bought directly off the shelf now for

Making science readily available for people Larking’s delight at the response – a career highlight for her – highlights her passion for translating science from a meaningless jumble of jargon to the layperson into practical applications. “One thing I really like about my job is that I get the chance to look at the science and make it useful and readily available for people,” she says, admitting she’s always “been a bit of a science nerd.”

She still manages the Johne’s Advisory Group. As manager for MIA Innovation Ltd – the industry’s 50:50-funded research partnership with Ministry of Business Innovation & Employment – Larking is responsible for leading and focusing 90% of the meat industry’s science research. She works closely with MIA Innovation manager Richard McColl and the Food Safety Science Research Centre.
Hailing from Whakatane, the former co-dux of Whakatane High School graduated with a BSc honours degree in chemistry from Victoria University of Wellington in the early 1980s.
Larking is a big fan of emerging technologies like artificial intelligence, machine-learning, visioning and non-invasive testing systems to help with that.
DSIR snapped up the new graduate and her expertise grew as a scale up chemist in its industrial processing division, where she worked on moving chemistry from the laboratory bench into commercial scale drug production. She spent a lot of time in a full air-supplied body-suit there, because of the toxicity of the substances with which she was working.
“When we talk about wanting to make the meat industry better, a lot of the things that we’re aiming at – that our consumers expect of us – need these new technologies to bring them to fruition,” she says. “With most of our processing done in rural communities, it’s an opportunity to make manual labour jobs into high-end jobs to which people want to attain. It’s got to improve our businesses,” she says.
Another career highlight came during her 20 years at DSIR/Industrial Research Limited from working on the development of a drug that is used today in the treatment of metastatic breast cancer. At a particularly difficult stage of the early work, working with stainless steel reactors and 100 litre rotary evaporators – not the usual two litre versions used in normal laboratory work – she remembers a colleague remarking that if their work saved one person, getting through that day would be worth it. Now in commercial production, that product is extending the lifetimes of patients being treated for cancer.
Another big project she’s involved in developing is work by the MIA looking ahead at what a meat plant will look like in 20-25 years. Still in the early design stage, the project will help assess which of these emerging technologies, some of which are at the high-risk end of science, are going to be relevant for the sector.
When DSIR/IRL closed, she segued into managing the Meat Biologics
“But I would like to think that we’ll be using some of them – such as artificial intelligence and visioning systems, combined with genetics and other pre-slaughter data about the animals – wisely in our meat plants within the next 10-15 years, to make improved products and create better and safer jobs for our workforce.” December 2019/January 2020

Careers
Be the Expert and more! John Lawson, Lawson Williams Consulting Group On a day to day basis we work with a lot of experts. Food technologists, research scientists, quality specialists, engineers, demand planners, procurement specialists, production managers, technical sales specialists. The list goes on. Being an expert within your industry or organisation is a key factor in getting ahead in your career. The key, though, is being a “recognised expert”, so attendance at conferences and participation in relevant professional organisations like NZIFST is an excellent way of building your recognition in your area of specialisation. In today’s organisations however expertise alone doesn’t count. In essence you need to be seen to “get things done”, and this is where a lot of technical people come unstuck, we rely too often on the facts, the stats or the detail and forget how to influence. There is clear value in having influence at work: you get more done and advance projects you are responsible for and ultimately this leads to being more noticed. It is useful to recognise that it is harder today to gain influence in the modern work environment because people are more distracted. They are overloaded with information and have lower attention capacity. And yet it is more important than ever to command influence because of the increased pressure on results. We simply must get things done. Here are some tips on building influence to get things done. We all need to be more conscious about doing these things.
Listen up and ask questions Most of us run around with to-do lists in our heads and it shows: we are often distracted or preoccupied and ready to reach for our phones when talking to others. Develop a discipline of focus when talking to people and they will be more ready to back you and adopt your idea. Another guideline is to ask questions as often as you make statements, so your recognised style is synonymous with inquiry and dialogue.
Build more connections This doesn’t mean trying to win a popularity contest, its simply about building better and wider rapport with your colleagues. In today’s busy work environment, you want people to at least hear you out and not switch off soon after you start talking. Work on “personal connections” with your colleagues, allow them to get to know you so the next time you are needing their support they will have positive intentions or motives towards you.
Mind your body language We all make judgements about people from the way they appear and act. We have a lot of hard wiring which leads to us naturally assessing whether we trust a person or not. Often this relates to how they look and behave so don’t forget about your body language and use it to convey the right message.
Give people what they want Increase your influence by authentically reframing an issue into a benefit to the people you want on your side. What are their needs, perspectives and temperaments? Do some homework and find out what they need to hear and what will capture their attention. For each person you must answer the question “What’s in it for me.”
Map your strategy Its not scheming, its strategising. Create an organisational chart of decision-makers related to your project or issue. Consider at each level if you can influence or whether you need others to influence on your behalf.
Be Consistent Consistency at work means to always meet or exceed expectations. Your level of consistency manifests most obviously in whether or not you keep your promises and meet your commitments. People will more likely support others whom they feel can be relied on, so do things like arriving when you say you are going to, being consistently open and communicative, and meeting deadlines. To be more successful at work today we all need to be more influential. For most of us it requires us to be more conscious of our sub-conscious. We need to think and be more proactive in doing the things that lead to people supporting what we want to achieve at work rather than relying on the natural way we behave and hoping for the best. Successful careers today more often require proactive strategies around influence.

Earle Lecture
“A Future for New Zealand Food” the 2019 Earle Lecture Presented by Dr Kevin Marshall Allan Main, FNZIFST The Earle lecture is a biennial award presented to a distinguished recipient who has made notable contributions to the impact of engineering and technology in New Zealand. It is hosted jointly by the Manawatu Branches of the Royal Society of New Zealand and the Institute of Professional Engineers and honours the contributions of Dick and Mary Earle, well-known to NZIFST, recognising their immense contribution to biotechnology and food technology regionally, nationally and globally. Early in October Dr Kevin Marshall, a long-standing Wellington member of NZIFST and the JC Andrews Awardee in 2006, delivered the 2019 Earle Lecture in Palmerston North on the subject “A Future for New Zealand Food”. In his opening comments, Kevin confessed to having known the Earles for his entire career with his professional and personal paths intertwining with Dick and Mary’s since the 1960’s. Indeed Kevin admitted that his first ever job application as a fresh BE graduate was to Dick and Mary at the Meat Industry Research Institute of New Zealand ... he was declined! A short while later when Kevin enrolled at Massey University for his post-graduate degree it was under the supervision of Prof Dick Earle. Kevin has since experienced a long and distinguished career spanning an extensive cross-section of our key food export industries including dairy, fruit, meat and seafood. Kevin’s assessment of the prognosis for our food future derives from the insights enabled by that that deep knowledge of the New Zealand food industry, leading him to an alternative scenario from zealots who proclaim that our food future is vegan, and all animal farming in New Zealand must stop. Unlike those who proclaim doom unless we frame an animal-free future for Kiwi food, Kevin anticipates our core platform of animal-based food exports will be retained but reframed to a more sustainable model, supplemented by alternative uses of land in a few areas where overintensification of animal farming cannot be sustained even with better control practices. In preface to his lecture, Kevin professed his belief (informed by his personal GP) that there are “no bad foods but there are certainly bad diets” implying that public and individual health responds to managing long-run consumption rather than maligning single foods. Later reflection identified that this philosophical tenet likely embodies a broader Marshall doctrine that oversimplification of issues by distilling them to isolated factoids commends ineffective solutions to problems and causes irrational choices to be made. That position seemed to be reflected in the underpinning logic of Kevin’s analysis of the prognosis for animal-sourced foods in our future that followed. Kevin openly acknowledges that there are immense challenges ahead for our traditional food industries but is sure that these are not and must not be insurmountable. Indeed, in Kevin’s estimation the future for our animal farming food industry continues to be “exciting”.
The Earle Lecture 2019 was presented by Kevin Marshall
Not a popular view - a considered one Kevin admitted that this alternative view is not popular with the vocal echelons that name-call those professing that animal farming can be performed sustainably as “denialists” and then attack farmers as “social pariahs”. Kevin exemplified this citing the reception given his colleague Fonterra’s Dr Jeremy Hill who was recently on the end of a media roasting after presenting to a proteins conference a similar fact-informed assessment supporting a future, albeit a reframed future, for animal farming in New Zealand. Coincidentally, during this Earle Lecture I was seated with an anonymous local farmer and the relief with which Kevin’s alternative message was received was apparent on his face. At the conclusion of Kevin’s presentation this same farmer professed that this was “the first public meeting on the future of NZ farming I have attended where I have not felt hated”. Kevin’s lecture wove a path through familiar factoids and instead of declaring a bankrupt future for dairy and meat farmers arrived at New Zealand applying technological know-how to navigate a pathway that delivers sustainable animal farming to provide fully sustainable animalderived foods, particularly dairy and meat to premium markets. Kevin’s initial focus was a situation analysis assembling the generally agreed factual context framing future global food needs and requisite sustainability boundaries. This analysis drew on (and cited) a plethora of reports published in recent years generally delivered by multi-disciplinary international assemblies of subject experts. These collective assessments intersect at a consensus requiring substantially
It is not the world that is threatened, but the world as we know it, and time is short 34
Food New Zealand
Earle Lecture
Our New Zealand animal farmers operate at the most efficient, least environmentally impactful end of the sustainability spectrum.
more food (an increase of 70% in food supply by 2050) of higher nutritional quality whilst reducing the net environmental burden currently incurred. Intrinsic to that consensus was an expectation that Western consumers would substantially reduce consumption of animal-derived foods (meat and dairy). However in parallel with that reduction, emerging nations were anticipated to increase consumption of (sustainably produced) animal-based foods, particularly dairy products, in order to provide nutritional sufficiency. Indeed, under the Eat-Lancet scenario for universal nutritional sufficiency, global dairy production is required to double whilst meeting full sustainability standards. Kevin willingly conceded that these expectations undoubtedly present immense challenges for the world but addressing the conundrum is not optional – it must be achieved for the future of our species. It is not the world that is threatened, but the world as we know it, and time is short. However, Kevin’s treatise pointedly observed that the analysis of the global burden of animals-as-food producers is constructed around global average data for environmental impact with wide-ranging local deviations from those averages. At the unsustainable extreme is the practice of growing foods appropriate for human consumption to feed confined animals for inefficient conversion to meat and dairy. Simply to replace current worst performing sources of animal-sourced food with the best-in-world achievements is to contribute a global improvement. Relative to alternative sources of equivalent products, our New Zealand animal farmers operate at the most efficient, least environmentally impactful end of the sustainability spectrum. This reality is enabled by fortuitous natural advantages (eg a temperate climate supporting year-round forage growth allowing continuous free-range grazing) and technology gains enabled by highly educated, collaborative and motivated farmers being fast adopters of emerging science and technology. That same capacity of Kiwi farmers to adopt new technologies will facilitate ready implementation of environmental impact mitigation technologies as they emerge keeping our animal products at the leading edge of sustainable animal production. So rather than a threat to our established animal-based foods farming industry Kevin infers current pressures provide opportunity for a significant number of New Zealand’s farmers who already operate at the upper decile of global environmental efficiency to deliver nutrientdense foods with demand in excess of what can be supplied from our geographic footprint. After all as Kevin observed, at best we can only feed a population of only 50 million (or half of one percent) of the world’s 10 billion people. For the foreseeable future it is assured that world-wide demand for animal protein foods will exceed what can be sustainably produced on our land, even if consumption is limited to a rare luxury for affluent consumers. Our future positioning with animal-derived foods will be to affluent premium niches founded on accountability to its clean-green-sustainable heritage. Critical to that opportunity will be providing robust evidence of sustainability and ensuring authenticity through tools of provenance traceability. And what of the plant-based alternatives? Are they the solution they purport to be?
Not all proteins are created equal Lately a flood of foods mimicking milk and meat has populated supermarket shelves in New Zealand supermarkets belatedly following the “analogue” trend present in other countries for many years. While these products are positioned as equivalents to traditional animal-derived foods, indeed they even wear their names – “milk”, “cheese”, “chicken”, “burger”– a quick review of their nutritional panels demonstrates that even at the most superficial standard of delivery of macronutrients most of these products fail to provide the nutrients for which these foods have become staples. A label review of protein levels provided by non-dairy products parading in the dairy case as equivalents to regular cows’ milk quickly shows that most provide significantly less crude protein than derives from the traditional product. The data shown in this address considered New Zealand market examples of almond, soy, rice, coconut and oat consumer “milks”; only the soy example approached the crude protein level of commercial cows’ milk. Almond “milk” provided a quarter of the protein content, oat one-eighth and rice and coconut had effectively no protein. Milk is a dietary staple due to its delivery of essential nutrients, notably protein and calcium. But the unsuspecting shopper selecting a nondairy alternative is potentially doing so oblivious to the short-changed nutrition that choice provides. When comparisons are made on the basis of cost per gram of protein, every non-dairy option is more expensive than basic dairy. That deficiency is evident even before attention turns to protein quality, a more opaque matter that is not directly evident to the consumer. As scientifically literate consumers we are the exception in realising that not all proteins are created equal. The reference standard for food protein quality is the digestible indispensible amino acid score (DIAAS). DIAAS data consistently shows that animal-derived proteins have a higher sore than plant-sourced proteins, so requiring higher consumption of plant proteins to provide nutritional equivalence. Applying these standards to the protein delivery of dairy and non-dairy consumer products, nutritional equivalence for the protein provided implies soy beverage has twice the climate impact and oat milk 8 times the impact of true dairy milk. This might be the appropriate time to cite Douglas Adams from Hitchhiker’s Guide to the Planet: “All you really need to know for the moment is that the universe is a lot more complicated than you might think, even if you start from a position of thinking it's pretty damn complicated in the first place.” Kevin is eager to ensure that the complexities are not swept under the carpet and ignored. To do so may cause irrational choices, like totally replacing our animal economy with crops and trees with resultant economic and social turmoil. The choices we make need to be informed and evidence-based. Hitherto Kevin suggests that such balance has not been evident in the discussion.

Dr Bronwen Smith – in memoriam Dr Bronwen Smith passed away on 1st August 2019, dying of lung disease. Bronwen grew up on a farm near Whangarei and like all farmers was very practical and could turn her hand to many things. She came to the University of Auckland as a mature student, having spent time demonstrating the latest electric sewing machines, which involved travelling around New Zealand. By all accounts she was very good at it and Pfaff were disappointed when she left for academia. Bronwen did her PhD with Professor Philip Harris, investigating the structure and function of plant cell walls (dietary fibre) of pineapple, onion, cabbage and ryegrass. With help from Dr Roger Newman of IRL she did pioneering work using solid-state NMR to understand how the polysaccharides that make up plant cell walls interact with each other to form such complex structures. Enjoying research, she was pleased be appointed, in 1997, as the first Postdoctoral Fellow in Food Science when Food Science started at the University of Auckland and then became the first lecturer in Food Science. She developed the programme along with Laurie Melton, and was Deputy Director prior to her retirement at the end of 2012, due to ill health. Bronwen was a

Bronwen Smith with Laurie Melton on her last day at the University in Auckland in 2012 - enjoying a good laugh tower of strength in the struggle to set up the Food Science programme. She was an accomplished lecturer and researcher but most of all she excelled at mentoring students. She supervised dozens of BSc (Hons), MSc and PhD theses as well as Postgraduate Diploma dissertations. If a student was required to hand in their thesis first thing on Monday morning and Bronwen found out at 5.00pm on the Friday that wasn’t going to be possible, she would spend the whole weekend helping them in order to meet the deadline. Bronwen also made a major contribution to starting the Wine Science programme at the university, involving herself in designing the wine making factory and research laboratories at the Tamaki campus as well as planning the course work. She was involved with the Forest and Bird Society and put together a number of submissions on their behalf and was also a member of Auckland Botanical Society. I found her one of the hardest working, most dedicated people I have met at any university. She contributed to lecturing, research and pastoral care with a total commitment that is seldom equalled. The students always came first. Only after she resigned, due to ill health, did people realise her huge contribution to establishing and maintaining Food Science at the University of Auckland. Effectively it required two people to replace her. She was an excellent colleague and wonderful friend. While always serious about her work she enjoyed a good laugh often at her own expense. As a former PhD student said “I will always remember her radiant calm, positivity; her loyalty; and her scientific rigour. Her beatific smile and encouraging words have stayed with me after all this time." She is sorely missed by her colleagues and her former students. Laurie Melton, FNZIFST

Branch News Auckland An evening with Kay McMath – learning how to judge Ice Cream In October, the Auckland branch welcomed Kay McMath, ice-cream judge extraordinaire. Kay was going to teach us a little bit about what is involved in judging the Ice Cream Awards. The whole event was members-only and fully-booked, so it’s no surprise that there was an atmosphere of excitement throughout the entire evening. Kay began by giving a background to the Ice-Cream Awards, and a history of icecream in New Zealand. Turns out, New Zealanders consume around 26 litres of ice cream each, per year, well ahead of Australians and Americans. Even with an active domestic market, the export of ice cream is a significant market, with exports of over 9000 MT of icecream going mainly into Japanese, Vietnamese and Pacific Island markets, equating to $40 Million in sales. Ice-cream manufacture in New Zealand predates commercial refrigeration. In 1866, the Empire Hotel in Wellington used ice obtained from frozen lakes in the US. A few years later, some of our iconic ice cream brands were established. Rush Munro’s and Peters Ice Cream cropped up in 1930, Tip Top in 1935 (the name was derived from a diner’s compliment). By the 1950s, we had 49 different ice cream companies. The 1950s saw the introduction of the Jelly Tip and the Topsy. Hokey Pokey ice-cream came from using the broken pieces from Cadburys Hokey Pokey bars. As for the New Zealand Ice Cream Awards, the event is now in its 23rd year and Kay has judged for 16 years. This year there were 308 different ice cream entries within 13 different categories. In recent years there

Auckland Branch Committee members, left to right: Bethany Glenn, Sarah Leakey, Nick Parker, Bonnie Lam with Anand Mohan, pictured at the Auckland Branch Christmas Garden Party has been a huge increase in the numbers of gelatos and sorbets; mainly due to the higher price they demand, with a lower milk solid content requirement. As for our judging/tasting workshop– Kay started us off with with a standard Vanilla, typically of 10 – 11.5% fat, good to calibrate and tune your palate. Next were the premium ice creams and gelatos. Third tasting was the open creative entrants from this years Awards. Last year’s winner was Kiwi Onion Dip ice-cream, with chips supplied for tasting. Kay commented on how truly creative people get in this category – such as creating salmon and dill flavours. Naturally, there is a Kid’s category, complete with their very own ‘Yum to Yuck’ scale for judging. The one thing our table learned is that all the ice-cream entries that we tried were gold award winners – they were all delicious! While we were tasting, we had forms in front of us – exactly the same as those used for judging. The criteria are: appearance, body and texture, and flavour. There are 21 different judging notes to look out for within these 4 categories – all adding to 100 points. Margie Hunt, Auckland Branch Chair
Christmas Party The members of the Auckland Branch began their end of year celebrations early with the annual Christmas Party in mid-November. It was held at the well-known Cornwall Park Bistro. Just over 60 members attended in their best 'garden party' attire. The evening began with petanque and canapes, and was closely followed by a lovely Christmas feast. There was a number of games across the evening, which was wrapped up with a brilliant group get-to-know-your-industry-mates game. A big thanks is owed to Cornwall Park Bistro for hosting us, and to the committee for all their hard work throughout the year! Bethany Glenn 38

On 30 October a group of members gathered at Tegel Foods for a presentation from Chris Brown from AsureQuality. This talk was arranged by Jasmin Estrera who works at Meadow Mushrooms and whose experience working with AsureQuality suggested that this subject may be of interest to members. New Zealand exports produce valued at billions of dollars each year. MPI seeks the services of IVAs (Independent Verification Agency) to help ensure the country’s excellent reputation for export is maintained. Chris Brown is the IVA Operations Leader for AsureQuality. Chris is an expert on phytosanitary certification, which is the movement of fruits, vegetables and nursery stock, whilst preventing the spread of plant pest and diseases around the world. Chris described the evolution of AsureQuality and its functions today in auditing, food contaminant testing, biosecurity, diagnostics etc. AsureQuality describe themselves as “Global experts in food safety and quality”. There was lively interest in biosecurity and especially fruit fly incursion and how this could be controlled should it occur.
The FODMAP diet On 12 November, a large group of 20 to 30 members and other interested colleagues gathered at ESR to hear Leigh O’Brien from Dietary Specialists speak to us on the Fodmap diet, a dietary intervention for irritable bowel syndrome. Most of us were strangers to this diet, and Leigh spent some time explaining to us the symptoms of Irritable Bowel Syndrome (IBS) and the pain and discomfort that people suffer with this condition. She then described what Fodmaps are. This acronym stands for Fermentable Oligo-, Di- and Monosaccharides and Polyols. These molecules draw water into the small intestine where they are fermented by the microbes in the gut, producing gas. The colon distends because of the increased gas and fluid with resulting bloating, diarrhoea, wind and pain for people with IBS. In a low Fodmap diet those sugars are reduced. It is an elimination diet for 6-8 weeks with various Fodmaps being reintroduced one at a time, in a very structured way, over 8-12 weeks. The diet is very personalised and works best with input from a dietitian. The gut microbiome is affected on a low Fodmap diet, reducing numbers of Bifidobacterium in particular, so phase one of the diet needs to be well planned to prevent deficiencies.

Central Branch members at Salt and Wood Brewery, Waikanae, enjoying their “not Christmas dinner" Bob Olayo, branch chair, thanks Leigh O’Brien after her presentation on Fodmaps Leigh discussed the published research which addresses the efficacy of this diet and ongoing research in both Australia and New Zealand. Monash University and the Royal Prince Alfred Hospital have strong programmes addressing this diet. Leigh’s presentation produced lively discussion and questions and her audience were well informed by the end of the evening. This had been a great networking and educational evening.

Central FSANZ; “Trends in Processing Aids” On August 15, our “after work” meeting featured Branch Chairman Ben Sutherland, Principal Food Technologist at FSANZ providing an update on processing aids, that mysterious set of food additives that may generally be omitted from an ingredient list (but not from allergen statements). Ben informed us that a processing aid is one of the materials listed in Schedule 18 of the Code that is present in a food in order to perform a technological purpose during food production but does not perform a technological purpose at the time of sale. Leading examples are enzymes, catalysts, antifoam agents, ion exchange media, filtration media, fining agents, vegetable peeling agents, etc. Processing aids are required to be used at the minimum effective level within GMP. Ben described the rigorous process for approving a new processing aid which is driven by ensuring there is a technological need within assured food safety. In recent years the number of approved processing aids has grown rapidly, largely due to an influx of applications for new food enzymes. It was noted that application of GM technologies has abated this rush of applications, and Ben outlined the review processes for such applications which also weigh up the nature of the host organism and the genetic modification technology applied to effect the host GMO. Ben concluded his presentation with some examples of processing aid usage in foods, and a discussion on consumer misconceptions about processing aids (e.g. assuming that any “processed food” by definition contains processing aids).
Salt and Wood Brewery visit and dinner This was marketed as “not our Christmas dinner” after previous years’ events scheduled closer to Christmas found many members were too busy to attend. Wellingtonians arrived at the Waikanae venue by train minutes before the brewery tour kicked off at 5.00pm, while the Palmerston Northers were able to get in a round of beer and snacks before the arrival of their Capital cousins. We were pleased to be hosted by Brewer Paul, who was quick to note other brewers in our midst. He talked us through the brews and aspects of the business, fielding numerous technical beer-making and business-related questions. The craft was evident in the wide range of styles that fully supplied the Salt and Wood and several other local establishments, businesses wider afield and internet sales. Nine beers are available in the range, including kettle soured ales, barrel aged and wild fermented beers. Relatively small batches are brewed in a typically adventurous manner. The dark stout “Iron Sands-Oat Rye Stout” was a notable treat as were many of the pale ales. Many sampled the beers shortly afterward in the form of a 6 glass tray, choosing from the sampling notes. Then the big decision on which beer should be enjoyed with a meal of choice. The various meat cuts are smoked on site and barbequed in large and tasty servings. There was no further technical fare, no one missed the quiz, or any serious challenges and simply, enjoyed food, art beer, and conversation at the end of another working week. John van den Beuken, FNZIFST
Kevin Marshall – A Future for NZ food When Dr Kevin Marshall presented his Earle lecture in October, he vowed that he was “on a promise” to wife Julie that this would be his last such public presentation. Always up for a challenge, NZIFST Central Branch Committee determined to persuade Kevin to re-present this lecture to our members, many of whom did not have an opportunity to attend the original presentation. We succeeded in that persuasion and Kevin presented his Earle Lecture to a live audience of 19 members and guests in Wellington and to virtual attendees in Palmerston North (19 people) and several others in a range of locations including FSANZ Canberra. The content of the Earle lecture is covered elsewhere in this edition on page 34. The lecture has been recorded with the intention of it being made available to NZIFST members elsewhere.
This was an extremely interesting presentation that provoked a great deal of discussion from the assembled group. On this experience other branches might consider approaching FSANZ to run a similar session with your members.
Kevin’s views were well-received by our members who enjoyed hearing that despite significant challenges, there remains a positive future for the New Zealand Food Industry and it remains an essential plank for our future economy.

Lee Neville from Hastings District Council gave HP/ PB branch members an overview of progress on the establishment of a food innovation hub in Hawke’s Bay
Hawke’s Bay/Poverty Bay Food and beverage industry supporters update On Thursday 17 October, members of the Hawke’s Bay/Poverty Bay branch gathered at the Hawke’s Bay Business Hub to hear three presentations from local support organisation for the food and beverage industry. The first speaker was Lee Neville from Hastings District Council. Lee is the council’s economic development manager and gave us an overview of progress on the establishment of a food innovation hub in Hawke’s Bay. The Food Innovation Hub has recently received a $12 million investment from the Provincial Growth Fund, which has in turn kicked off an investment drive led by Lee, to gather a $6 million investment from local businesses. The proposed innovation hub, which would be modelled, at least in part, on the Waikato Innovation Park would look to address key trends identified in the research feasibility and business case study: • Environmentally sustainable production and packaging • Plant-based production • Functional food and beverage • Waste stream utilisation The hub would establish a variety of services in Hawke’s Bay, including co-working and hot-desk space, seminar facilities, a “food hall” to display food processing equipment available in the region and a possible centre of entrepreneurship in association with the Eastern Institute of Technology. Looking more broadly, the food innovation hub would look to become a centre of excellence for the entire Hawke’s Bay and East Coast region, generating jobs and income while supporting local businesses. Exciting times ahead!
successful, with over 30,000 hub sign-ins since its inception. September 2019 was a record for sign-ins, with over 1013 registered. Finally, we heard an informative update from Nicky Solomon of the NZ Food Innovation Network (NZFIN). NZFIN is a national network driving and developing innovative food products. They act as a “dating agency”, setting up start-ups and entrepreneurs with local businesses. At the conclusion, we adjourned to the Urban Winery for nibbles and a drink, and a dancefloor side view of the local salsa dancing scene, which appears to be thriving in Napier! Many thanks to the Hawke’s Bay Business Hub for hosting us, the Urban Winery for the food and drinks, and to the speakers for their informative presentations. Pete Revington
Next up we heard from Rachel Campbell from Business Hawke’s Bay (BHB). BHB acts as the business-led economic development agency for the region. They have three main work streams: “attract”, “build”, and “connect”.
Nelson
The “attract” stream is all about bringing business to Hawke’s Bay, as well as targeting people and skills and helping businesses target investment opportunities.
David List discussed Food Tech volunteering opportunities and his recent experience supporting a social enterprise in Java. Aliet Green is a coconut palm sugar processor with a fair-trade ethos.
Under “build”, the BHB helps start-ups, or existing businesses further develop their brand or products. A significant example Rachel described was the goat and sheep ecosystem. BHB helped create a working group in Hawke’s Bay looking at the extensive opportunities the sheep and goat sector can offer, not just in dairy, but also in fibre and meat.
David’s 4-week assignment was organised by Australian Business Volunteers and financed by an Australian Aid Friendship Grant. He was able to identify hundreds of thousands of cost-savings simply by studying mass balances, overheads and rework. He worked with accounts, production and NPD to improve systems. David is keen to enthuse others to volunteer when opportunities arise with NGO’s like VSA or ABV. He was chuffed to find three Massey classmates from the 1980s in the audience.
Finally, through the “connect” stream, BHB offers several networking and training events, as well as being part of a collaborative group that set up the Hawke’s Bay Business Hub. The Hub has been wildly 40

Food Innovation Waikato’s drying facilities. Twenty Waikato branch members braved the wind and rain to tour the Food Innovation Waikato site at Ruakura. Despite the weather we had a very informative tour around the present 500kg/hour drier facility, looking into the drier room, blending, packing, re-con, boiler room. Outside we saw milk reception, the tank farm, effluent treatment. This drier has been such a successful enterprise for FIW and the Innovation Park that it runs 24/7/365 on high-value sheep and goat dairy products (Infant Formulae, Nutritionals etc) to the extent that it has proven necessary to build a new facility, right next door, to raise the capacity of the site. Donning hard-hats we then toured the new building to see the progress of the project. The new drier will produce 1500 kgs/hr and will free up the smaller drier for its original purpose – trial runs, small production batches, experimenting with drier settings to optimise a variety of products. Some clever design attributes in this new section: the experience of the FIW staff and the builders (TetraPak) has brought some elegant solutions to areas such as powder tipping, the fluid bed design and packaging. It will produce infant formula with all the necessary constraints, so we were lucky to see it before it goes “redline.” However, we were invited back to see the finished product this time next year. Watch this space. Well done FIW for another great night. Dave Shute and his staff have been doing such a good job and creating so much value for shareholders, the Innovation Park and NZ Inc. that they have made it necessary to employ twenty more people to staff the site. That’s a successful enterprise.
SweetAs Popcorn Fifteen Waikato branch members had a very informative tour around the SweetAs Popcorn site in Frankton. We were treated to a short video showing the history of the company, the products and the markets. Starting from a small food market stall and expanding as sales grew, the company now occupies a complete block in Frankton and is looking to expand its capacity further as markets grow. We then toured the factory which has a great set-up for viewing through windows while the staff went about the business of producing the very PoPular product – see what I did there? The history of domesticated corn goes back at least 5,600 years to Central America. Different varieties are used that pop into diverse shapes that take coatings differently, fit into packages differently and require variations in the cooking protocol to achieve a successful pop. Lots of questions and answers going back and forth led to fresh contacts being made with members with specific expertise to offer SweetAs and to show the benefits of the NZIFST network. SweetAs cook in oils that are varied depending on the target market. Coatings are applied with the oil or immediately after popping in a
Of course, we were treated to the tasting table. SweetAs have differentiated their flavours with combinations like Manuka Honey and Chocolate, Sweet and Salty, Salt and Vinegar. They do a cheese flavour, caramel, Sea Salt and are constantly experimenting with product development. They also use tasting panels at their larger customers to provide feedback on flavours for sale into supermarkets, service station franchises, theatre chains. SweetAs made the point that they are a Kiwi business and wish to keep their operation local and grow it here. The founder/owner Bill Neal is passionate about his business and is involved in all aspects including product development – who wouldn’t be? SweetAs are exporting to America and Asia as well as getting good sales in NZ and are on the threshold of expanding the business again to cope with growing demands. This is a business that is literally exploding.
Ecolab tank farm and Brewraucracy Brewery. Fifteen NZIFST members gathered at Ecolab in Te Rapa to tour the newly built tank farm. Ecolab have invested eight million dollars into a state-of-the-art load/unload facility on their manufacturing site. The old facility is being de-commissioned right next door and all the lessons learned in its growth and development were incorporated into the new facility. Safety is paramount with all manner of E-stops, showers, bundling and emergency contingencies available to keep staff and the site secure. The tanker unload bay has two-storeys to load in from the top and load out via pumps from the bottom. The various tanks in the farm are matched to the product they hold, and we were able to climb the cat-walk to view the site from above to see how product is moved around and then transferred to the adjacent manufacturing site. This is a very impressive facility that shows Ecolab’s confidence in the manufacturing sector in New Zealand and their ongoing intention to be part of the market. Thanks to Jo Thomson from Ecolab for hosting. We then adjourned to Brewraucracy BrewHouse for pizza and beer tasting hosted by Greig McGill, who gave us a tour of the brewery and a quick lesson on his brewing methods. Greig brews a variety of styles and his interesting views on the economics of hop supply were a surprise to many. Greig uses mostly American hops as New Zealand grown hops are so popular and consequently, expensive, that a small to mid-sized brewery like his cannot afford to use a lot of the locally grown product. NZ brewers are importing American and European hops while the northern hemisphere pays a premium for NZ hops as they are so aromatic and sought-after. Going by the reaction of the group, Greig’s beers are fine, whatever the source of his hops. Another great evening with NZIFST with more activities planned for next Colin Pitt December 2019/January 2020

STUDENT ESSAY
From the farm to the lab: a future with in-vitro meat Shiyu Ouyang, Massey University Albany This article was awarded third prize in the Food Tech Solutions NZIFST Undergraduate Writing Competition 2019. The annual competition is open to undergraduate food science and food technology students who are invited to write on any technical subject or latest development in the food science and technology field that may be important to the consumer.
Introduction As global population grows, the demand for meat is expected to increase (OECD-FAO, 2016). Meanwhile, human health, animal welfare and environmental impact are still the main issues that will affect global meat production and consumption (OECD-FAO, 2016). Problems such as animal diseases raise questions and concerns and the meat industry needs to find a way to address these issues. In-vitro meat, also known as “lab-grown” meat, is produced from isolated animal cells instead of living livestock (Bhat & Fayaz, 2011). Although this technology is still premature, its potential applications may help solve the problems that currently exist in the meat industry.
What is in-vitro meat? Unlike meat produced from living animals, in-vitro meat is “grown” from animal cells in a culture medium to produce tissues that resemble muscles (Bhat & Fayaz, 2011). These cells are known as satellite cells, which proliferate when stimulated, and form fibre-like structures similar to muscle tissue (Lincicum, 2010). Although it is difficult to replicate complex meat products such as steaks, it is possible for invitro meat to replace low-end processed meats (Pluhar, 2010). In fact, an artificial hamburger has already been made in the laboratory using synthetic meat (Mattick & Allenby, 2013). At this stage, it is not practical to produce in-vitro meat products due to high costs, but the technology still provides an interesting opportunity for the future meat industry (Mattick & Allenby, 2013).
Human health A major advantage of in-vitro meat is that, compared to conventionally produced meat, it is a more reliable source of food. The growth of farm animals is often affected by seasons, climate changes, disease outbreaks and many other factors that are difficult to predict or control (Bhat & Fayaz, 2011). In-vitro meat is not susceptible to these factors, and is therefore a potential solution to food security problems around the world. Compared to plant-based meat substitutes, in-vitro meat may be a better source of nutrients. Plant-based meat alternatives may be lower in protein than real meat, and may also be higher in fat and carbohydrates (Bonny, Gardner, Pethick & Hocquette, 2017). The fat content of in-vitro meat can be modified by the culture medium: unhealthy fats can be replaced by healthier fats and functional nutrients such as vitamins can also be added to the meat (Pluhar, 2010; Bhat & Fayaz, 2011). Therefore, it is possible that consuming in-vitro meat can help reduce the risks of cardiovascular diseases and other illnesses caused by high dietary fat intake. Foodborne diseases are a major concern for both consumers and 42

legislation makers. For example, after the swine flu outbreak in Europe, Russia stopped importing all pork products from the EU (OECD-FAO, 2016). The use of antibiotics has also raised concerns regarding food safety. It is believed that replacing existing meat products with invitro meat can prevent these issues, as in-vitro meat can be “grown” in a controlled environment, and thus lower the chance of chemical contamination (Bhat & Fayaz, 2011). In reality, a completely sterile environment can be difficult to achieve, especially on a large scale, and the use of antimicrobial substances may be inevitable (Bonny, Gardner, Pethick & Hocquette, 2017). In other words, the safety of invitro meat affects how it will be manufactured on an industrial scale, and as this technology remains experimental, it is unknown whether in-vitro meat will be a clean and safe alternative for consumers. Existing legislation framework is unable to regulate the production of in-vitro meat (Lincicum, 2010), and if it is to be mass-produced, new legislations must be in place to ensure its safety.
Animal welfare Animal suffering related to factory farming has been widely reported, and although there is legislation in place, law enforcement is often not enough to prevent the problems (Lincicum, 2010). As no livestock is required to produce in-vitro meat, inhumane treatment of farm animals can be prevented. The production of in-vitro meat, however, does require a continuous supply of satellite cells, as the proliferation of the stem cell is limited (Lincicum, 2010). Therefore, mother cells will have to be obtained from living animals, which still raises some concerns regarding animal wellbeing (Pluhar, 2010). If this can be done in a noninvasive and painless way, then the ethical benefits of in-vitro meat will certainly outweigh the concerns regarding obtaining cells from living organisms, allowing humans to consume meat without farm animals being treated brutally.
Environmental impact The obvious advantage of producing in-vitro meat is that it does not involve raising or slaughtering animals, and thus reduces the usage of land and agricultural materials such as animal feeds. It also eliminates by-products such as feathers, intestines and skin from the production process, and is therefore considered to be more efficient than conventional meat production. It is claimed that in-vitro meat requires 99% lower energy and 90% lower water inputs, compared to traditional meat manufacturing process (Tuomisto & de Mattos, 2011). Another aspect that needs consideration is greenhouse gas emission, which directly contribute to global warming. To most consumers, it may be surprising to find out that the meat industry is a major producer of greenhouse gases, contributing to 18% of total emissions around the

world (FAO, 2006). It is estimated that greenhouse gas production of manufacturing in-vitro meat is 40% lower than that of traditional meat (Tuomisto & de Mattos, 2011). However, some researchers argue that the environmental impact of producing artificial meat cannot be accurately estimated, as the interactions between humans, farm animals and the environment is complicated (Mattick, Landis & Allenby, 2015). For example, byproducts can often be further processed into other commercial goods, and eliminating these by-products means that they will need to be replaced by synthetic materials, which may in turn have unexpected impacts on the environment. As the technology is yet to be applied on an industrial scale, it is difficult to perform an analysis on its environmental effects without making assumptions, and thus the estimations may deviate from reality (Mattick, Landis & Allenby, 2015).
Consumer acceptance One of the greatest challenges faced by in-vitro meat is the resistance from consumers. Indeed, words like “artificial” and “synthetic” have never been consumers’ favourites, and the idea of consuming a slab of meat “grown” in the laboratory can be difficult to accept. A study involving participants from several European countries revealed that some participants would reject the product simply because of its synthetic nature, while others are concerned about the safety, nutrition value, appearance and taste of the meat (Marcu et al., 2015). However, the potential benefits of in-vitro meat may attract consumers who are concerned with animal welfare and environmental issues (Verbeke, Sans & Van Loo, 2015). To vegetarians who value the health benefits of foods, in-vitro meat may not be very appealing (Verbeke, Sans & Van Loo, 2015). As many questions about in-vitro meat are yet to be answered, it seems early for consumers to make a decision. As the technology evolves and the product improves, consumer perception of in-vitro meat may change over time.
Conclusion In-vitro meat is a potential solution to problems associated with the production and consumption of conventional meat. Although experiments on in-vitro meat remain tentative at this stage, it is possible that a variety of meat products can be engineered and produced in the
laboratory environment and if production can be achieved on a mass scale it is possible to commercialise synthetic meat to replace existing meat products. However, such a transformation will require the meat industry to overcome both technical and market barriers. Furthermore, the environmental impact of in-vitro meat needs to be carefully evaluated, and effective legislation must be in place to regulate the production process.
