Abstract

The invention discloses a hydrolyzed fish collagen processing process. The process includes steps: removing fish scales and fish skin, draining after clearing, and keeping for standby application; soaking the fish scales and the fish skin in water, and performing sterilization treatment; subjecting the fish scales and the fish skin to enzymolysis, filtering, and removing filter residues to obtainenzymatic hydrolysate; feeding the enzymatic hydrolysate into a molecular weight screening system to obtain collagen solutions graded according to collagen molecular weights; concentrating the collagen solutions, drying, and treating with a magnetic rod to obtain fish collagen. The hydrolyzed fish collagen processing process has advantages that before enzymolysis, the fish scales and the fish skinare subjected to high-temperature sterilization to damage tissues in the fish scales and the fish skin, so that acid and alkali swelling treatment can be avoided, enzyme activity can be guaranteed, and enzymolysis completeness is improved; a fish collagen product is free of fishy smell, low in ash content, simple in production process, low in cost, great in taste, high in water solubility and lowin salt content.

Description

technical field [0001] The invention relates to the technical field of natural product extraction, in particular to a processing technology for hydrolyzing fish collagen. Background technique [0002] Collagen is a white, opaque, unbranched fibrous protein that plays the role of binding tissues in animal cells. Collagen is rich in 18 kinds of amino acids except tryptophan and cysteine, which maintain human growth There are 7 essential amino acids. Fish collagen is mainly extracted from tilapia, cod fresh skin and fish scales through biological enzyme directional shearing technology. It has high digestion and absorption, excellent thermal stability, and excellent bio-affinity, and can well perform its functions of penetration, moisturizing, and repairing. At present, the preparation of collagen from discarded fish skin, fish scales, and fish bones has become one of the research hotspots at home and abroad. [0003] The total amount of fishery resources that can be develope...
