EFFECT OF ELASTIN HEDROLYSES ON THE CHEMICAL COMPOSITION AND SOME OXIDATION INDICATORS IN COLD-STORED GROUND BEEF

Abstract

This study was aimed to investigate the effect of elastin hydrolysates extracted from bovine skin on the chemical composition and some indicators of oxidation in minced beef stored in refrigeration at a temperature of 2 °C for a period of 12 days. The study included 6 treatments T1 (without addition), T2 addition (1000 ppm) of elastin hydrolysates per kg of meat, T3 addition (500 ppm) of elastin hydrolysates per kg of meat, T4 addition (1000 ppm) of collagen hydrolysates per kg of meat, T5 addition (500 ppm) of collagen hydrolysates per kg of meat and T6 addition of the antioxidant BHA (0.01) per kg of meat. the transactions were stored by cold storage for periods 1, 3, 6, 9 and 12 days, and some chemical tests were conducted for them, The results of this study showed that treatments to which elastin hydrolysate was added showed a significant improvement in the chemical composition (moisture, protein, fat and ash) of ground beef stored in cold storage compared to the control treatment. It also showed a significant decrease (P<0.01) in oxidative stress indicators through a decrease in TBA values in chilled ground beef compared to the control treatment. We conclude that the addition of elastin hydrolysate to minced meat stored in cold storage at different storage periods improved the chemical composition of the meat and achieved high antioxidant effectiveness through a decrease in oxidation indicators represented by a decrease in the TBA value. And improve the water holding capacity of WHC, From the above, this study aimed to know the effect of elastin hydrolysate in maintaining chemical properties and reducing oxidation and thus prolonging the period of cold preservation of meat.
