There is an increasing demand in the grain-handling chain to control purity and sorting accuracy of different classes and varieties of grains. It is needed to ensure that varieties with specific qualities are delivered at high purity and quality. To control the grain-handling chain that stretches from farmers to transporters, to storage silos, to end-users (maltsters and brewers) in the market, low-cost, rapid tests are needed. Lab-on-a-chip capillary electrophoresis provides a rapid identification method. This method has been used for identification of different barley varieties and related malt. Distinction can be made between members of a set of 50 commonly grown European barley and malt varieties. Genuine barley samples were malted in a micromalting plant. The technique can also been applied to the separation of proteins from other grains.

Martina Gastl apprenticed as a brewer and maltster from 1994 to 1996 in Klosterbrauerei Andechs, Germany. She studied brewing and beverage technology at the Technische Universität München-Weihenstephan, Germany. She graduated as an engineer in 2002. From 2002 until 2006 she completed her Ph.D. degree on the "Technological Influence on Lipid Degradation in Terms of Improvement of Beer Flavour Stability." She is currently assistant professor and head of the raw material research group at the Lehrstuhl für Brau- und Getränketechnologie in Weihenstephan. Since 2008 she has been working on her post-doctoral lecture qualification; her research interest involves "Characterization and Interaction of Flavour Active Taste Compounds in Cereal Based Beverages Influencing Beverage Harmony."
