Problems solved by technology

However, using the above raw materials to coat crystalline amino acids, either the effect of slowing down the dissolution and loss in water is poor, or the absorption rate of crystalline amino acids in the digestive tract is too fast or too slow to be adjusted to a reasonable range, so the actual use effect is not good. relatively limited

Abstract

The invention belongs to the technical field of feed additives, and discloses coated amino acid, a preparation method and application thereof. The coated amino acid comprises crystalline amino acid and a coating agent, wherein the coating agent is a combination of saturated fatty acid and rice protein. According to the invention, the coated amino acid is small in dissolution loss in water, and absorption of crystallineamino acid in digestive tracts and absorption of protein binding amino acid are more synchronous, so that the utilization rate of the amino acid is increased, and the feed cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a coated amino acid and its preparation method and application. Background technique [0002] In aquafeeds, some crystalline amino acids are usually added to make up for the lack of amino acids in the formula. However, because crystalline amino acid is easily soluble in water and has a high solubility in water, it causes waste of materials, thus limiting its practical application in aquaculture compound feed. In addition, the absorption of crystalline amino acids in feed by aquatic animals is too fast, which is not synchronized with the absorption of protein-bound amino acids in feed, so that the effect of feed amino acid balance and complementarity cannot be achieved, resulting in a decrease in the utilization efficiency of amino acids. [0003] Studies have found that coating crystalline amino acids can reduce their dissolution and loss in water, and slow down the absor...
