Abstract

The invention discloses a process for preparing peptide which comprises vanadium, which comprises using stewing material which is rich in protein after scouring with acidulous water solution, mixing with vanadate, using soybean peptide as fermentation accelerating agent, grafting fermenting bacterial strain into raw material which is stewed, fermenting for 6-72h under 20-40 DEG C, washing, drying, disintegrating in ultrafine to obtain vanadium-enriched polypeptide powder, removing peptide with large molecular to obtain vanadium-enriched liquid peptide, and chelating through adding vanadate toobtain vanadium-enriched peptide whose peptide concentration is over 60%, and vanadium element concentration is over 100 mg / kg.

Description

technical field

[0001] The present invention relates to the preparation method of biological raw material for food and medicine processing, especially the preparation method of peptide containing organic vanadium; the present invention also relates to the product prepared according to the method. Background technique

[0002] Vanadium is one of the essential trace elements for human beings. Whether it is inorganic vanadium, organic vanadium, or biotransformation vanadium, as long as it can be absorbed under the safe limit, it can produce medical and health effects.

[0003] The absorption rate of inorganic vanadium by organisms is very low, the maximum absorption rate of cations is 10%, and the absorption rate of anions is only 0.01-0.1%. At the same time, inorganic vanadium has high toxicity and side effects, and the effective dose for human treatment is 100-1000 times that of animal experiments. Therefore, the currently known inorganic vanadium cannot be used clinically. ...
