【 摘 要 】
The purpose of researches is comparative assessment of effectiveness of effect of natural antioxidants at storage of raw materials of the poultry processing industry. For achievement of a goal addition of antioxidants is provided in control specimens. The experimental data 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. Antioxidants 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. At reproduction vitamin introduction, acid number in 28 days of storage turned out less on average on 0, 84 mg KOH/g, at addition of redoxon, Rutinum and dihydroquercetinum, respectively, on 1.27; 3.52 and 3.61 mg KOH/g-in comparison with a control specimen. So, at tocopherol addition this index in test pieces was 1.3 times less, in comparison with monitoring. As a result, in 28 days of storage of test pieces, acid number reached smaller values on average for 29%, and peroxide-by 1.5÷1.7 times, concerning control specimen. 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.
