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

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.
