Abstract
The purpose of researches is comparative assessment of effectiveness of effect of natural antioxidant at storage of raw materials of the poultry processing industry. For achievement of a goal addition of antioxidants is provided in control specimens. Addition of dihydroquercetin to the emulsified skin of broiler chickens, at a rate of 0.50; 0.75 and 1.00 kg per 100 kg of raw materials, the way to achieve a significant level of their oxidative damage. The experimental data’s are obtained as a result of carrying out laboratory researches on definition of acid and peroxide numbers in raw materials of the poultry processing industry in 7, 14, 21 and 28 days of storage. Antioxidant with various effectiveness promoted decrease in extent of their oxidizing decay. Addition of antioxidants in test pieces of raw materials promoted essential braking of its oxidizing decay. Their acid number over the period of the experiment was 1.3-1.7 times lower, and the peroxide number 1.8-3.6 times lower than in the control samples stored without the addition of an antioxidant. The received results convince of high performance of use of dihydroquercetin as the fissile antioxidant that provides a possibility of its use along with the available analogs.
