Amino acid concentrate preparation method and amino acid-containing feed

Abstract

The invention discloses an amino acid concentrate preparation method; amino acids can be effectively extracted from residues (such as bran, corn gluten and bean dregs) of plant seeds after starch processing or animal products (such as animal blood meal, bone glue, fish scales, hair and animal viscera) or microbial fermentation by-products (such as glutamic acid bacterial dregs, citric acid bacterial dregs, Baijiu bacterial dregs, and beer bacterial dregs) and are concentrated to obtain an amino acid-containing concentrate. The process steps are concise, the yield of the amino acids is high, and the method is suitable for a variety of raw materials which can only be discarded previously, and has great economic value and environmental protection value. The invention also provides a feed product prepared from the amino acid concentrate prepared by the method. The feed product containing proteins or amino acids is prepared by mixing the concentrate containing 50% amino acids with other feed raw materials, such as corn crumbs and the like; the feed product can be absorbed well after animals eat the feed product, and the period of animal appearing on the market is shortened.

Description

technical field [0001] The invention relates to an amino acid extraction method, in particular to a preparation method of an amino acid concentrate and an amino acid-containing feed. Background technique [0002] Engels scientifically said "Protein is life" more than two hundred years ago. Over the past two hundred years, the abundant facts of modern scientific research and technological invention have proved that Engels' scientific judgment is very correct. So far, scientific research has once again proved that the life phenomena shown by all organisms are the result of proteins. [0003] It can be seen that protein substances are crucial to living things. In recent years, the country has intensified its efforts in environmental protection. Since the reform and opening up, in the production process such as monosodium glutamate, a large amount of fermented liquid containing fungal residues is mainly discharged directly. This will cause environmental pollution, ammonia and...

Problems solved by technology

Generally speaking, protein-rich animal products that cannot be processed will be dried and made into powder to add to the feed, but the animal's absorption of it is very limited, or even almost impossible to absorb and utilize, and the price of these products is also very low , cannot get a win-win situation

[0012] Animal products are generally animal blood products, blood meal, bone glue, and by-products of various fish. If they are directly dehydrated and powdered and mixed into animal feed, they will be difficult to be completely absorbed by animals, reducing economic value and prolonging the release of animals in reverse. cycle

[0013] Chinese patent 02146459.6 discloses a method for purifying the waste residue liquid in the wine making industry. The main object of purification is distiller's grains, especially distiller's grains containing high cellulose. Extraction of Amino Acids from Dry Yeast Powder for Research

The disadvantage of this technology is that feed water and compound enzyme preparation are added first, then inoculated with protease-producing bacteria or / and lactic acid-producing bacteria and microbial strains that decompose glucosinolate or / and gossypol, and then fermented to obtain the processed The cotton rapeseed meal obtained, thereby obtaining the non-toxic high-nutrition feed fermented cotton rapeseed meal protein material, and using it as a protein raw material component to form the cotton rapeseed meal animal feed by adding 15%

However, the disadvantage of this technology is that the microorganisms grown in the fermentation process consume a large amount of original protein in the raw material, resulting in waste
