Biologic antioxidant used for animal feeds

Abstract

The invention relates to a biologic antioxidant used for animal feeds. The antioxidant comprises, by weight, 10-30% of tea polyphenol, 10-20% of Folium Phyllostachys extract, 1-5% of vitamin E, 5-7% of citric acid, 8-10% of adsorption particles and 35-55% of a carrier. Compared with antioxidants in the prior art, the biological antioxidant has the following advantages: all raw materials are natural and green, and the synergistic effects of all the raw materials are used, so the ability of the antioxidant is greatly improved; and the biologic antioxidant used for animal feeds contains a special phenolic acid component, so trace element variable valency metal ions in the feeds are effectively passivated, the catalysis effect on oxidation of the feeds is avoided, and the antioxidant especially has a reliable protection effect on high-copper and high-zinc feeds.

Description

technical field

[0001] The invention relates to a feed additive, in particular to a biological antioxidant for animal feed. Background technique

[0002] With the development of my country's feed industry, feed antioxidants have also made great progress. For a long time, people have been using synthetic antioxidants such as ethoxyquinoline (EQ), butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), tert-butylhydroquinone (TBHQ) and Propyl gallate (PG), etc., although these synthetic antioxidants are convenient to use and have good anti-oxidation effects, they are irritating and carcinogenic, and at the same time cause changes in the quality of meat products. For example, 30EQ powder, which is common on the market, If the 60EQ powder is added in a large amount, it will cause "yellow fat meat" and cause meat quality and safety problems; There is no way to remove free radicals in animals.

Examples

Embodiment 1

[0033] The following steps were adopted to prepare biological antioxidant 1:

[0034] (1) Biological antioxidant formula: effective content of 25% tea polyphenols 30%, bamboo leaf extract 10%, vitamin E 1%, citric acid 5%, white carbon black 8%, defatted rice bran 16%, zeolite powder 30%.

[0035] (2) Production method of biological antioxidant

[0036] (2.1) Adsorb vitamin E with white carbon black to prepare a small material, pass through a 60-mesh sieve for use;

[0037] (2.2) The crystalline granular citric acid needs to be pulverized first, and then passed through a 60-mesh sieve for use;

[0038] (2.3) Put half of the rest of the carrier into the mixer first, then put in 25% tea polyphenols, bamboo leaf extract and materials (2.1) and (2.2), and finally put the other half of the carrier into the mixer, mix for 5 minutes, and pass through a 60-mesh sieve , a vested biological antioxidant product.
