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.
