Feed with enzymatic small peptide-additive complex and preparation methods thereof

Abstract

The invention provides three methods for preparing a feed with an enzymatic small peptide-additive complex and the corresponding feed. On the basis of the original conventional feed, an additive capable of forming a coordinating covalent bond with an amino group is added, the vegetable protein and / or the animal protein can be hydrolyzed into a small peptide compound by the action of at least one protease, the small peptide compound contains an amino group having an empty track, and the additive capable of forming the coordinating covalent bond forms a coordination compound with the amino group, so that the additive is more stable, which overcomes the shortcomings of fear of light and oxygen, and deactivation while meets acid and alkali; on this basis, other types of additives can be added,and other types of additives can be formed in the cluster formed by the coordination compound, so that the problem of stability of other types of additives can be solved.

Description

technical field [0001] The invention belongs to the field of feed processing, in particular to a feed with enzymatic hydrolysis of small peptide-additive complexes and a preparation method thereof Background technique [0002] In the prior art, there are three processing methods: 1. Emulsify and homogenize the three feed materials of oil, protein and whey powder, and then dry them to become solid powder; 2. Mix oil, protein, whey powder, feed Additives are emulsified and dried to become feed raw materials; 3. The three feed materials (or one of them) of oil, protein and whey powder are homogenized, emulsified and enzymatically hydrolyzed with enzymes, and then dried. Become a solid powder. [0003] The above process plays a positive role in improving feed processing efficiency, promoting animal digestion and absorption, and improving feed emulsification and solubility. However, the first and second methods have a significant disadvantage: the protein in the prepared feed i...

Problems solved by technology

However, the first and second methods have a significant disadvantage: the protein in the prepared feed is not hydrolyzed into small peptides, which cannot be directly absorbed by the animal's digestive tract, and the biological potency is low; in the third method, there are small peptides , but the content of small peptides is low, the advantages of small peptides cannot be brought into play, and the absorption of feed additives is also poor, so it is impossible to effectively utilize and comprehensively utilize feed additives, and it is also impossible to tap the potential performance of small peptides and feed additives. great waste
