Sea eel small molecular peptide extracted from sea eel bones and extraction method thereof

Abstract

The invention relates to a method for extracting sea eel small molecular active peptide from sea eel bones. The method comprises the following steps of 1, sea eel bone processing, 2, low-temperature smashing, 3, cell dissolution processing, 4, biological enzymolysis processing and 5 postprocessing; the ratio of the obtained sea eel small molecular peptide with the molecular weight being 0-480 d is 88.5% or more; the sea eel small molecular peptide is applicable to a peptide for diagnosis, a peptide vaccine, an antibacterial activity peptide, a cell factor simulation peptide, a cell factor simulation peptide, an antiviral peptide or an anti-tumor peptide and a peptide health care product.

Description

technical field [0001] The invention relates to a technique for extracting peptides from fish bones, in particular to a method for extracting small molecule peptides from eel bones. Background technique [0002] Collagen extracted from animals such as yak bones has certain limitations in absorption rate, and with the risk of mad cow disease, this more traditional method is not recognized by people, and people increasingly recognize it from The corresponding nutrients are extracted from fish. [0003] The current extraction is mainly to extract collagen from fish scales and fish skins, such as tilapia fish scales, deep-sea fish skins such as cod skins, but these extracts have a wide molecular weight distribution and are not easy to absorb. The existence of outstanding problems such as low absorption rate has greatly prevented the realization of new health care concepts such as high nutritional value, safety, and good absorption that modern people pursue. [0004] On the oth...

[0003] The current extraction is mainly to extract collagen from fish scales and fish skins, such as tilapia fish scales, deep-sea fish skins such as cod skins, but these extracts have a wide molecular weight distribution and are not easy to absorb. The existence of outstanding problems such as low absorption rate has greatly prevented the realization of new health care concepts such as high nutritional value, safety, and good absorption that modern people pursue.

[0004] On the other hand, the volume of traditional collagen or protein peptide extracts is large, the production cycle of the product is long, and the enzymatic solution is not completely removed, which affects the quality of collagen. The resulting finished product often has a bitter smell and poor taste. If filtered If the level is not enough, the water solubility of the product will be poor, which will directly affect digestion and absorption, and the solution to the problem of high salt content in fish extracts is not ideal, which will affect the taste of the product

[0005] Although with the advancement of technology, people have used the advantages of membrane separation technology to improve product quality to a certain extent, but they have not fundamentally obtained small molecule active peptides.
