Microencapsulation peptide-containing fat powder feed additive and production method thereof

Abstract

The invention discloses a microencapsulation peptide-containing fat powder feed additive and a production method thereof, and the microencapsulation peptide-containing fat powder feed additive contains core material and wall material, wherein the core material comprises 20-50 percent of grease; and the wall material comprises 20-50 percent of peptide powder, 3-5 percent of casein, 1-5 percent of monoglyceride, 1-5 percent of sucrose ester, 1-3 percent of carrageenan and 10-30 percent of maltodextrin. The production method of the feed additive comprises the steps of: mixing and stirring water phase and oil phase according to the formulation, and then carrying out high pressure homogenization and spray drying for completing primary embedding; and carrying out secondary embedding on the obtained microcapsule fat powder by using 5-10 percent of HPMC with the embedding rate reaching up to more than 95%. The obtained peptide-containing fat powder can be easily added into feed and has extremely high nutritional value, so that the feed additive is excellent in quality.

Description

【Technical field】 [0001] The invention belongs to the technical field of feed additive preparation, and relates to the preparation of a microencapsulated peptide-containing fat powder feed additive for feeding by using oil and peptide powder as main raw materials and a manufacturing method thereof. 【Background technique】 [0002] At present, there are two main states of adding fat in feed: liquid and solid. Liquid fat is mainly directly added to the feed by spraying, but adding too much will easily cause the feed to form agglomerates, uneven distribution and easy oxidation when exposed to air, and requires special spraying equipment, which is inconvenient to add on site. The solid fat can be directly mixed with other ingredients of the feed, the distribution is more uniform, the processing is convenient and the addition ratio is relatively large. According to the difference of its preparation process, solid fat can be divided into uncolored type and coated type. The uncoat...

Problems solved by technology

[0003] Protein, like fat, is the main nutrient substance of animals. At present, most of the feed is directly added, and the utilization rate is not high. In fact, the digestion and absorption of protein in the food is actually hydrolyzed into small peptides by proteases in the digestive tract, and then use the intestinal mucosa striate border Existing peptide carrier active transport mechanism to accomplish
