The dependence of the total content of antioxidants in talgan on the stages of its manufacture and the type of raw material

The aim of the study was to analyze the total content of antioxidants (CSA) in the national Khakass product talgan at different stages of its production from barley and wheat grains. The grain was grown on the territory of the Bey district of the Republic of Khakassia characterized by favorable climatic conditions, from the point of view of growing grain with a high content of antioxidants. To determine the CSA in the grain, 2 solvents were used - hot bidistilled water and 70 % ethanol. SSA measurement was performed with the help of the device "Color Yauza-01-AA". Among all the samples of barley and wheat, higher rates were recorded when using hot bidistilled water as eluent. It was found that the value of CSA in barley grain and its processed products had been higher compared to wheat. The effect of exceeding the CSA levels in intermediate barley or wheat product after the stage of roasting grain in comparison with the initial raw material was established. The registered increase in the value of the SSA in talgan was either mainly due to the parts of the grain that were devoid of bran (in the case of barley), or due to the entire grain (in the case of wheat). The level of CSA in barley bran compared to the original grain did not change, and in wheat bran increased. At the same time, a higher CSA value was found in bran in comparison with the finished product (talgan) when they were extracted with hot bidistilled water, the difference with the latter was expressed by 13.6 %.
