This method describes how to determine not only the variety of barley but whether a lot of barley consists of a mix of varieties.
Barley intended for malt production as well as barley malt
Separation and identification of the protein (hordein) fraction of barley or barley malt by means of gel electrophoresis. The method is suitable for all types of barley, as long as reference substances are available. However, the method cannot be used to identify barley varieties used to produce malt that has been so strongly modified that the protein fraction is almost completely degraded.
