Grease emulsifying agent for coated feed and preparation process thereof

Abstract

The invention relates to an animal feed additive, i.e. a composite grease emulsifying agent for a coated feed, and a preparation method thereof. The composite grease emulsifying agent for the coated feed comprises the following components in raw material ratio in percentage by weight: 10 percent to 30 percent of glyceryl monostearate, 10 percent to 30 percent of sucrose monolaurate, 5 percent to 20 percent of sorbitol anhydride monolaurate, 5 percent to 10 percent of glycerol monolaurate, 20 percent to 50 percent of polyethylene glycol and 20 percent to 50 percent of silicon dioxide. The preparation process of the grease emulsifying agent comprises the following steps of: firstly, carrying out heat preservation after heating and melting high HLB (Hydrophile-Lipophile Balance) value raw materials; adding silicon dioxide to adsorb to form fine particles; and then dissolving low HLB value raw materials and polyethylene glycol by an organic solvent, uniformly spraying the solution on the fine particles to obtain a finished product. Four food emulsifying agents with different HLB values, which are selected by the invention, are processed by scientific compatibility, are suitable for emulsifying various greases in the feed, have stable emulsifying effects and can keep the state of not breaking emulsion for a long time; after being subjected to coating processing, all of four emulsifying agent ingredients can tolerate high temperature treatment and are suitable for pelletizing processing of the feed.

Description

1. Technical field [0001] The invention relates to an animal feed additive, in particular to a film-coated feed compound oil emulsifier and a preparation process thereof. 2. Background technology [0002] With the rapid development of modern farming, the growth performance of livestock and poultry has been continuously improved in the breeding process, and its requirements for nutrients, especially energy, are also getting higher and higher. As a high-energy feed ingredient, fat is often used in livestock and poultry diets to increase dietary energy. However, due to the immature development of the digestive system and the insufficient secretion of endogenous bile salts and lipases, it is difficult for young animals to fully emulsify the fat in the feed, which greatly limits the digestion and absorption of oil, so it must be treated externally. Sources add substances that improve fat utilization. Adding emulsifiers to feed can improve the digestion and utilization of fat by...

Problems solved by technology

However, some studies have shown that adding bile salts to feed for a long time will affect the secretion of endogenous bile salts and pancreatic lipase through the enterohepatic circulation, causing feedback inhibition of bile salts and pancreatic lipase, resulting in fat loss.
