Livestock-poultry meat modifier containing lycopene as well as preparation and application thereof

Abstract

A livestock-poultry meat modifier containing lycopene consists of the following components in percent by mass: 5-10 lycopene, 10-20 vitamin E, 0.015-0.03 selenium, 0-0.02 chromium, and the balance of carrier. The meat modifier can be prepared by the following steps: dissolving the lycopene solid powder by a small amount of normal hexane, mixing gelatin and sucrose in mass ratio of 3:7-1:9 to form microcapsule wall material, and conducting homogenization, wherein the mass of the lycopene solid powder accounts for 10-20% mass of the mixture of the gelatin and the sucrose; and mixing the lycopene microcapsule with the vitamin E, the selenium and the chromium in mass ratio, and then adding the blance of carrier. The livestock-poultry meat modifier containing lycopene is added in livestock-poultry complete feed, in 0.05-0.1 percent by weight. Tests prove that the meat modifier can reduce occurrence of PSE meat, effectively inhibit muscle fat oxidation, increase muscle water holding capacity, reduce muscle drip loss, stabilize meat color and improve meat tenderness, maintain meat flavor and prolong the shelf life of meat.

Description

technical field [0001] The invention belongs to the field of chemical technology, relates to animal production and feed processing technology, in particular to a livestock and poultry meat quality improver containing lycopene and its preparation and application method. Background technique [0002] In recent years, in order to promote the development of meat products and meet people’s needs for meat consumption, animal husbandry workers have carried out a lot of work. On the one hand, they have cultivated lean-meat livestock and poultry varieties, on the other hand, they have comprehensively promoted full-price compound feed and intensive breeding. Technology has significantly improved the carcass composition of livestock and poultry, reduced the deposition of subcutaneous fat, increased the lean meat rate and growth rate, shortened the feeding cycle, greatly increased the output of livestock and poultry meat, and achieved unprecedented diversification of meat varieties. The...

Problems solved by technology

[0007] Lycopene (Lycopene) is an important carotenoid, also known as Lycopene, the molecular formula is C 40 h 56 , Molecular weight 536.85. Lycopene is a highly unsaturated linear hydrocarbon compound composed of 11 conjugated double bonds and 2 non-conjugated carbon-carbon double bonds. It is currently found in nature with the strongest antioxidant capacity. -Carotene can interact with singlet oxygen and react with various free radicals. Its antioxidant capacity is 2 to 3 times that of β-carotene and 100 times that of vitamin E. At present, lycopene has unique ability to eliminate singlet The ability of lycopene, strong antioxidant effect and free radical scavenging ability, as well as anti-cancer, anti-cancer, and cardiovascular disease prevention effects make it a functional food additive. However, domestic and foreign literature has not yet seen the use of lycopene as an animal feed additive. application.
