The assessment of the maintenance of antioxidants in barley grain and oats on the basis of its physical indicators

The simple, express and low-cost method of se-lection assessment of material on this chemical in-dicator is necessary for conducting total contents of antioxidants (TCA) evaluation. The purpose of the study was the analysis of dependence of TCA in the grain of barley and oats from indicators "the mass of 1000 grains" and "filminess of grain". As objects of research 17 samples of summer barley and 18 samples of oats of the Siberian selection grown in 2015 on the bare fallow predecessor on Beysky GSU of the Republic of Khakassia and the experimental farm "Minino" of the Research Insti-tute of Agriculture, Russian Academy of Agricultural Sciences of Krasnoyarsk region were used. The determination of sizes TCA in the grain of barley and oats was carried out in two stages. In the first the extraction of tests or hot distillated water, or 70 % ethyl alcohol was carried out. In the second stage the measurement of the electric current aris-ing at oxidation of the studied substances on the surface of a working electrode at constant potential 1.3 B by means of the Yauza-01-AA Color device was carried out. The mass of 1000 grains, the indi-cator of filminess of grain of barley and oats were determined by standard methods. The Values of TCA in the grain were in the limits: from 40.0 to 77.5 mg / 100 for barley; from 29.9 to 52.2 mg / 100 for oats. The maximum sizes of TCA were recorded at the grade of barley of Acha and a grade of oats of Sayan Mountains, and minimum levels of TCA were characteristic respectively for grades the Be-ginner and Tubinsky. The dependences between TCA in grain on the one hand were not revealed and weighing 1000 grains - on the other. Essential posi-tive dependence between TCA was found in grain and the indicator of its filminess. The application as eluent of bidistillated water promoted the increase of narrowness of communication between the sign of filminess of grain and an indicator of TCA. It was suggested that possible application of the received results in an express indirect assessment of samples of barley and oats on the total maintenance of anti-oxidants in grain.
