Processing method of microcapsule coated fatty powder

Abstract

The invention discloses a processing method of microcapsule coated fatty powder, and relates to the field of processing, adding and producing of fatty powder feeds. The processing method comprises thefollowing steps of selecting vegetable fat and lecithin in a certain proportion, performing mixing together to form mixed fat, adding the mixed fat to an emulsifying pot, adding a food grade emulsifying agent to the emulsifying pot, performing heating for emulsifying the mixed fat, placing the emulsified mixed fat in a reaction kettle, adding lipases, performing enzymolysis and shearing, adding microcapsule wall materials to the mixed fat after enzymolysis and shearing, performing multistage high-pressure homogenizing treatment, spraying the mixed fat subjected to high-pressure homogenizing treatment with an atomizer, and performing drying with dry wind for heat dissipation so as to prepare stable granules. The processing method has the beneficial effects that the fat for feeds is uniformly distributed in special wall material coated microcapsules, through spray drying, powder is processed, the fat micro-granules and air are effectively separated, the oxidative deterioration risk is thoroughly eliminated, and the granule diameter achieves nanoscale, so that the obtained microcapsule coated fatty powder can dissolve in water completely.

Description

technical field [0001] The invention relates to the field of processing and adding fat powder feed, in particular to a method for processing fat powder coated with microcapsules. Background technique [0002] As an important energy substance, oil is widely used in feed. However, oil containing a large amount of unsaturated fatty acids is easily oxidized to produce various oxidation products during feed storage, especially at high temperature and in an environment rich in metal trace elements, which not only affects Feed odor and palatability, and the normal physiological and biochemical functions of animals will be greatly affected after ingestion, which will bring losses to the breeding industry. At present, there are three main prevention and control measures for the problem of oil oxidation in the feed industry: one is from The source began to strictly control the quality of oil; the second is to rationally adjust the feed formula, reduce the amount of trace metal element...

[0002] As an important energy substance, oil is widely used in feed. However, oil containing a large amount of unsaturated fatty acids is easily oxidized to produce various oxidation products during feed storage, especially at high temperature and in an environment rich in metal trace elements, which not only affects Feed odor and palatability, and the normal physiological and biochemical functions of animals will be greatly affected after ingestion, which will bring losses to the breeding industry. At present, there are three main prevention and control measures for the problem of oil oxidation in the feed industry: one is from The source began to strictly control the quality of oil; the second is to rationally adjust the feed formula, reduce the amount of trace metal elements, and reduce the catalytic effect; the third is to use compound antioxidants, but the above measures have limitations, such as affecting the end-use effect of feed, antioxidants Poor thermal stability, etc., so it is very necessary to make a coated fat powder with tiny particles, easy to absorb, and easy to dissolve in water
