Preparation method of isinglass bioactive peptide

Abstract

The invention relates to the fields of traditional Chinese medicine and biotechnology. Isinglass bioactive peptide is prepared from fresh or dried isinglass as raw materials, and by crushing, pulp homogenization, enzymolysis, centrifuging, sterilization and ultrafiltration. A preparation method comprises adjusting the pH of isinglass after the crushing and homogenization to 6-8; adding flavor protease, neutral protease and papain (1:1:1) to the isinglass and performing enzymolysis, wherein 5000-10000 enzyme activity units (u) of enzymes are added to each gram of the isinglass, and a temperature is controlled to be 50-60 DEG C, and enzymolysis time is 3-6 hours; conducting enzyme deactivation, the centrifuging, the sterilization, and the ultrafiltration so as to obtain an isinglass bioactive peptide liquid with a molecular weight of 5000 daltons or lower; and preparing the isinglass bioactive peptide liquid into freeze-dried powder products, oral liquid products or capsule products. Theisinglass bioactive peptide has the pharmacological activity of invigorating the kidney, replenishing essence, nourishing yin, beautifying skins, nourishing tendons and veins, strengthening body functions, relieving fatigue quickly, and promoting wound healing. The method is scientific and precise in working procedures, high in operability, and beneficial for industrial production.

Description

technical field [0001] The invention relates to the fields of traditional Chinese medicine and biotechnology, in particular to a method for preparing a fish maw active peptide that has the functions of nourishing kidney and essence, nourishing yin and beauty, nourishing tendons, strengthening functions, rapidly eliminating fatigue, and helping wound healing. Background technique [0002] Fish maw is fish maw, which is the dried product of all kinds of fish maw. It is famous for its rich gelatin, and its alias is fish maw. The swim bladder is taken out from the belly of the fish, cut open and dried, and it is rich in protein and colloid. It can nourish yin, strengthen the kidney and cultivate essence, which can quickly eliminate fatigue and help the wound recovery of surgical patients. . Fish maw is made by washing the swim bladder of large fish and drying it in the sun. The ranking of the top fish maws is the king of isinglass in order: money cod maw (yellow lip fish), whi...

But now it’s just a waste of resources to eat as ingredients and can’t achieve the expected effect, because the rich collagen contained in fish maw has a molecular weight of 80,000 to 200,000 Daltons, which can be absorbed by the human body very little. There is no good absorption of fish maw products for sale, and there is a serious waste of raw materials
