RATIONAL PARAMETERS OF PRESERVATION OF BY-PRODUCTS OF LEATHER PRODUCTION FOR USE IN PRODUCTION OF FODDER ADDITIVES AND ANIMAL FEED
Abstract
The article presents the results of research to determine the rational technological parameters of preserving by-products of leather production for use in the manufacture of feed additives and animal feed. It was determined that the use of the feed antioxidant "Alniredox liquid", in amounts of 0.5 and 0.25 g per 1 kg, mixing of raw materials in a mixer with this antioxidant for 4 and 3 minutes (w=500 rpm), respectively, followed by drying at t=180°C for 0.5 hours at technological stage I, t=150°C for 2.5 hours at technological stage II, t=110°C for 2 hours at technological stage III (for fleshing), t=180°C for 0.5 hours at technological stage I, t=150°C for 2 hours at technological stage II, t=110°C for 2 hours − at the III technological stage (for flakes) allows for lower values of acid and peroxide numbers of products from this byproduct of the leather industry (up to 7.2 mg KOH/g and 0.05 % J2), including after 1 month of storage (t=2±2°C) (up to 6.7 mg KOH/g and 0.02% J2, respectively) compared to samples without the use of this preservative.
