Description
Technical Field
The invention belongs to the technical field of animal feed, and relates to emulsified nano fat powder and a preparation method and application thereof.
Background
The grease is a main source of essential fatty acid in livestock and poultry breeding, is also a preferred additive for improving the energy concentration of feed, and has an important function in the livestock and poultry breeding. The oil and fat are very easily oxidized, so that the flavor and the product quality of the oil and fat are damaged. At present, the grease processing technology at home and abroad mainly adopts a grease hydrogenation technology or a grease powdering technology. The technique of powdering an oil or fat is to coat the oil or fat with a coating wall material to prepare a microencapsulated powder and to emulsify the oil or fat for more efficient use. However, the size of the fat particles of the emulsified oil directly affects the use efficiency.
Meanwhile, the main problems of the oil added into the feed at present are that the oil proportion is unreasonable and the fatty acid is unbalanced; the excessive fatty acid causes waste, and the insufficient fatty acid causes the problems of insufficient nutrition, poor development and the like of animals.
CN106901045A discloses a fat nutrition composition, which comprises the following raw material components in parts by weight: 15-35 parts of medium-short chain mono-diglyceride, 10-15 parts of medium-chain triglyceride, 10-20 parts of coconut oil or palm kernel oil, 3-10 parts of triglyceride type fish oil, 10-30 parts of OPO structural fat, 3-8 parts of carnitine, 1-5 parts of spermine and 40-90 parts of coating. The patent application provides a plurality of medium-short chain mono-diglyceride which are compounded according to a certain proportion, but the emulsification effect is slightly poor, and the absorption of the medium-short chain mono-diglyceride is influenced. CN10162046A discloses a compound emulsifier for livestock and poultry feed, which is prepared from the following raw materials in parts by weight: the emulsified fat powder comprises, by weight, sucrose fatty acid ester SE-520-25 parts, sucrose fatty acid ester SE-1340-60 parts and monoglyceride 20-30 parts, wherein the fatty acid structure in the emulsified fat powder provided by the patent application is unbalanced.
At present, the using effect of the nanocrystallized grease on animals is reported, but the nanocrystallization technology is immature, the production cost is high, and the nanocrystallization technology is difficult to apply to the animal husbandry industry. Therefore, it is desirable to provide a method for preparing nano fat powder.
