The study proved the feasibility of a new generation of anti-oxidant bioflavonoid dihydroquercetin, which has a high degree of biological activity, and a positive effect on meta-bolic reactions and the dynamics of a number of pathologi-cal processes in the body. The paper explored the possibility of using Dihydroquercetin as an antioxidant, an objective conducive to increasing length of service of storage collagen raw poultry processing. To achieve the objectives of the study, it required laboratory tests to determine the acid and peroxide numbers of the homogenized skin of broiler chickens after 7 days of storage. Dietary supplement “Dihydroquercetin” was added to the test samples at the rate of 0,5; 0,75 and 1,0 kg per 100 kg of the basic raw material, in compliance with the recommended standards. Adding dihydroquercetin to raw control samples contributed to a significant reduction in degree of oxidative deterioration. Introduction antioxidant in studied concentrations helped to reduce the acid number to 31–59 %, and the peroxide number – 2–4 times with respect to these parameters in the control sample. The results assure high efficiency in use of dihydroquercetin as active antioxidant that emphasizes its advantages compared with existing analogues.
