Methods used for the determination of proteins in barley.Peer-reviewed article

A. DOLEŽALOVÁ, H. VRTĚLOVÁ

Practically in all countries growing barley the percentage of proteins present in malting barley is steadily rising and there is consequently a general tendency to include the protein content into criteria specified in binding standards applied to evaluate the quality of barley. Prior to incorporating the protein content criterion into an appropriate Czechoslovak National standard it is necessary to develop a reliable and time saving determination method. Methods used at present can be divided into 4 groups. In the first group are methods base on the mineralization of samples, in the second are methods relying on color reactions of barley extract, to the third group belong methods based on volumetric determination of elementary nitrogen and in the fourth group are all other analytic methods. The authors suggest a number of improvements which should be introduced into the existing technique, especially by using modern instruments.
