Problems solved by technology

[0006] Chinese patent CN1113117 discloses a method for producing antioxidants, but the technical solution disclosed in this patent has a high cost on the one hand, and on the other hand, short-chain fatty alcohols such as ethanol and butanol need to be used in the process to reduce the antioxidant complex. Viscosity, but these substances are highly volatile and flammable, because the process needs to be carried out in a relatively high temperature environment, so the safety is not high, and there is a risk of explosion
Although the technical solution disclosed in the above patent is simpler in process operation, the patented product has poor antioxidant effect and has the following disadvantages: firstly, the choice of emulsifier is not good enough, because the HLB value of glyceryl monostearate is 3.8, which belongs to pro-oxidant Oily emulsifier, for the environment where the oil phase and the water phase coexist, choose a hydrophilic emulsifier and a lipophilic emulsifier for compounding, so that the emulsification stability will be better, and the two phases are not easy to separate, otherwise the material will be sprayed on the surface of the carrier. Stratification phenomenon, followed by a single synergist, the ability to chelate metal ions with variable prices is not strong

Abstract

The invention relates to a compound antioxidant for feed and a preparation method of the compound antioxidant. The compound antioxidant comprises, by weight, 80-300 parts of combined antioxidant, 55-130 parts of combined synergist and 18-35 parts of combined emulsifier, wherein the combined antioxidant is an antioxidant compounded by ethoxy quinoline, dibutyl hydroxy toluene, butyl hydroxy anisole and tertiary butyl hydroquinone; the combined synergist comprises lipoic acid, citric acid, phosphoric acid and water; the combined emulsifier comprises soybean lecithin, polysorbate and glyceryl monostearate. Compared with the prior art, the compound antioxidant has the advantages that multiple antioxidant raw materials are compounded and dissolved to permeate mutually and be sufficiently evenly mixed, the effect of the antioxidant is brought into full play, the severe defect of insufficient contact caused by steric hindrance between small solid particles formed by crushing and feed is eliminated, and the compound antioxidant is low in production cost, simple in process, safe, high in operability and free of environment pollution.

Description

technical field [0001] The invention belongs to the technical field of feed, and relates to a feed compound antioxidant and a preparation method thereof. Background technique [0002] As an important energy substance, oil is widely used in feed for livestock, poultry and aquatic products. The unsaturated fatty acids contained in it are easily oxidized during the storage of feed, especially in high temperature and high humidity environments, resulting in a large amount of free fatty acids. Once ingested by livestock and poultry, it will seriously affect the health of animals, cause low immunity, increase susceptibility to diseases, and seriously affect the absorption and utilization of feed nutrients. For feed with severe oxidation , will cause animals to refuse to eat, or even die from poisoning, which will bring huge economic losses to the breeding industry. In order to avoid oxidative changes in feed, the use of antioxidants has become more and more widely recognized. ...
