Preparation method of sea-ear active peptide

Abstract

The present invention relates to a method of manufacturing abalone bioactive peptide, including: dewatering and drying the abalone offal, grinding into 100-200 mesh of fine powder, adding 10-30 times of pure water, cooling down and than adding the proteolytic enzyme for enzymolysis, heating for exterminating enzyme, cooling down and then centrifugation for removing the insolubles, adding 95% ethanol in the supernatant to make the system concentration achieves the 50-60% of ethanol concentration, centrifugation for removing precipitation after the supernatant is static, performing pressure reduction and concentration to the supernatant for removing ethanol, decolorizing by use of activated carbon, and finally drying to get the abalone bioactive peptide. The invention uses the abalone offal for preparing abalone bioactive peptide, and extracts the obtained abalone bioactive peptide, which has health-care effects such as eliminating fatigue and improving immunity. The manufacturing method has reasonable process, simple operation, easy realization for the industrial production, eutrophy processed products and health-care efficacy.

Description

technical field

[0001] The invention relates to the technical field of extracting active substances, in particular to a process for preparing abalone active peptides from abalone leftovers. Background technique

[0002] We know that abalone is one of the precious seafood. It is a high-protein, low-fat, low-cholesterol food and is known as the "crown of seafood". Abalone is rich in protein, as well as more nutrients such as calcium, iron, iodine and vitamin A. The meat of abalone also contains an ingredient called "baosu", which can destroy the necessary metabolites of cancer cells. In addition to being rich in nutrition, abalone has very fresh and tender meat, so it has been loved by people since ancient times. With the breakthrough of abalone farming technology, there are more and more enterprises processing abalone on a large scale. However, the leftovers in the abalone processing process - abalone viscera have not been fully utilized. According to the research, the visc...
