Feed fat meal and its processing method

Abstract

The invention discloses a fat powder and a preparation method thereof. The fat powder is rich in sn-OPO and medium-chain fatty acids, and optional oils include pangasius oil and coconut oil, and coconut oil, palm kernel oil, and tallow can also be further added , transesterified oil. For the above-mentioned oil and fat raw materials, the composite emulsifier of the present invention is selected from soybean lecithin 30-50%, Tween-80 10-20%, corn starch 3-20% and sodium stearoyl lactylate 5-20%. The present invention further improves the utilization rate of the fat powder and improves the growth performance of the body through the improvement of raw materials and processes, and further solves the problems of stratification, deterioration, stability, etc. that are easy to occur in the fat powder processing process through the optimization of the fat powder preparation method. question.

Description

Technical field [0001] The present invention belongs to the field of lipid technology, specifically relates to a feed fat powder rich in sn-OPO and medium chain fatty acids and a processing method thereof. Background [0002] As the main source of animal energy supply, it is necessary to add a certain amount of oil to the animal feed of nursing sows, piglets, cows and so on. At present, common forms of added oil include the addition of liquid oil and fat powder, fat powder is easy to store, palatability is good, and can effectively supplement fat sources, which is currently receiving more and more attention. [0003] Fat is not only as an energy substance, providing essential amino acids for the body, but also can promote the absorption of fat-soluble vitamins, alleviate piglet stress syndrome, promote the growth and development of piglets, and currently add a certain amount of oil to the feed to improve the economic benefits of breeding. [0004] For short-chain fatty acids, esp...

Problems solved by technology

[0005] Although there has been some research on fat powder, there are still many problems to be overcome. For example, the emulsification effect of fat powder is poor, resulting in low utilization rate; for example, the structure of fatty acids is unreasonable, which may even affect the digestion and absorption of the body and cause constipation. For example, the length of the carbon chain, a reasonable combination is more conducive to the growth of the organism. Some studies have added deep-sea fish oil and supplemented EPA and DHA, but longer carbon chains will affect the absorption rate of the body.

[0006] Another important issue is the compatibility between triglycerides, the length of fatty acid carbon chain, the number of unsaturated bonds, the position, the reverse structure, and the specific structural composition of triglycerides, such as OPO, SSS, etc. Different molecular forms lead to The compatibility of different fats will vary greatly. When processing fat powder, emulsifier and preparation method are very critical

If it is not handled properly, for example, there may be problems such as poor stability, easy oxidation and deterioration, easy delamination after freezing, poor high temperature resistance, etc.
