Abstract

The study investigates the physico-chemical properties of wheat grain of the Bogarnaya-56 variety (grown in the Merkensky and T. Ryskulov districts), the Steklovidnaya-24 variety (Bayzak district), and the Bezzostaya-1 variety (Bayzak district) intended for milling, grown in the Zhambyl region.

Various techniques and methods for evaluating the qualitative characteristics of wheat grains were used during the research of the samples. The studied varieties were characterized by a high 1000-grain weight (30.2-39.7 g) and a volume weight of 743-794 g/l. The protein and gluten content varied in the range of 13.0-17.7% and 24-31%. The best gluten quality values according to the IDK readings were noted in the samples of winter wheat varieties Bogarnaya-56, grown in the Merkensky and T. Ryskulov districts, corresponding to the first quality group. Samples of wheat varieties Steklovidnaya-24 and Bezostaya-1 corresponded to the second quality group.

Based on the results of the study of technological properties of grain and physical and chemical indicators, it was established that the studied wheat complies with the standards of the third class. As a result of the assessment of physical and chemical properties, it was established that the grain of domestic varieties of winter wheat complies with the requirements of GOST 9353, which indicates its suitability for bakery production.
