Preparing technology for active nano-selenium brain peptide

Abstract

The invention relates to a preparing technology for active nano-selenium brain peptide. The preparing technology includes the following steps that 1, pig brain tissues are homogenized, enzymolysis degreasing is carried out on the homogenized pig brain tissues through lipase, hydrolysis is carried out through complex enzymes, and ultra-filtration is carried out to obtain brain peptide liquid, wherein the quantity of the added lipase is 0.05% to 0.15% of the weight of brain liquid, and the quantity of the added complex enzymes is 0.2% to 2% of the weight of degreased brain protein liquid; 2, a sodium selenite solution and an ascorbic acid solution are added into the brain peptide liquid, stirring reacting is carried out for 1 hour to 2 hours at the temperature of 40 DEG C to 55 DEG C, and reaction liquid is obtained; 3, spraying drying is carried out on the reaction liquid, and the finished product is obtained. According to the preparing technology, brain protein hydrolysate is degreased in the enzymolysis mode, the degreasing effect is good, environment pollution is avoided, and the biological activity of small molecule peptide and the safety of the product are guaranteed; meanwhile, the small molecule brain peptide obtained after enzymolysis serves as a medium template to adsorb and stabilize nano-selenium, the active brain peptide is combined with the nano-selenium, the physiological functions of the brain peptide and the physiological functions of the nano-selenium are promoted and synergistically interact with each other, and the obtained product has the better treatment effect on various diseases such as insomnia, cephalalgia and hypomnesis.

Description

technical field [0001] The invention relates to a preparation method of brain protein powder, in particular to a preparation process of active nano selenium brain peptide extracted from pig brain tissue. Background technique [0002] Mammalian brain tissue is relatively compatible with human brain tissue, and various proteins, peptides, nerve growth factors, phospholipids, mucopolysaccharides, etc. contained in it can be used by human brain tissue. Using enzyme engineering technology, a large number of small molecular peptides, amino acids, coenzymes and other substances can be obtained from animal brain tissue, which is called brain protein hydrolyzate or brain peptide in the industry. According to research reports, more than 30 kinds of active peptides have been found in mammalian brain tissue. The functions of brain peptides are mainly manifested in two aspects: regulatory function and nutritional function. Regulatory functions include improving sleep and memory. Extend ...

Problems solved by technology

The existing technical solutions only prepare single-functional animal brain protein hydrolyzate or a certain form of elemental nano-selenium, and organically fuse nano-selenium with cerebroprotein or brain peptide to prepare more functionally active nano-selenium cerebroprotein or brain peptide No patent report yet

[0005] In addition, in the existing animal cerebroprotein or brain peptide extraction process, organic solvents (such as acetone, ether, ethanol, etc.) are generally used to degrease cerebroprotein hydrolyzate. The yield is high, but it needs to consume a large amount of organic solvents, which is easy to cause environmental pollution, high cost, inconvenience and danger to production operations, and active substances such as proteins and peptides may cause irreversible damage under the action of organic solvents for a long time denaturation inactivation
