Issue 21 / November 2017 Flour products testing Latest developments for quality control
Welcome to the latest issue of Global Milling Advances. This month we learn about the latest technology for monitoring grain temperature, testing the quality and characterictics of flour products and detecting the increase of residual starch in bran. We also discover the solutions for managing mycotoxins and get an insight into grain control and certification. We strive to provide relevant and useful information to our professional readership. Contributor submissions, press releases and feedback on our publications are always welcome.

There’s too much starch in that bran! Optimum extraction rate
Too much residual starch in bran means foregoing profit for millers. Bühler offers two ways out of the ‘residual starch dead end’ with its online measuring technology: the NIR Multi Online Analyzer MYRG or the Online Color and Speck Measurement MYHB. Both methods measure and report an increase in residual starch without loss of time making prompt correction possible.
In the grain milling industry the term extraction rate describes the amount of flour that can be made from 100 kg of grain. In modern milling operations, yield calculators continually monitor production and determine the degree of extraction. The goal of every miller when producing white, low-ash flour is to separate as much of the endosperm from the husk (bran) as possible. Bran is considered a by-product in milling and can be used as an additive for feed or sold as is.

Brabender GlutoPeak® optimises receipt of goods at WiesnethMühle By Markus Löns, Brabender® GmbH & Co. KG, Duisburg, Germany
A member of Wiesneth Mühle’s laboratory staff weighs out the distilled water on the Brabender GlutoPeak.
In the milling industry, being able to determine the quality of raw materials is fundamental. Being able to test them is an essential task. Wiesneth Mühle GmbH in Franconian Pommersfelden, Germany, has taken its quality management to the next level, at the same time introducing a time-efficient system. In what is one of Bavaria’s largest flour mills,

Every day, Wiesneth Mühle mills around 250 tonnes of wheat and rye. In summer, the vehicles belonging to the supplying farmers stretch in a queue way beyond the mill’s gates. A wide variety of other types of grain can also be recorded at two other sites in Nuremberg and Würzburg.
