Industry method of producing fish collagen peptide from fish skin and bone by an enzyme method

Abstract

The invention discloses a special method to extract collagen from fish peel and bone with complex prolease, which comprises the following steps: choosing salmon, AnKang fish peel and processing waste of fish product as raw material; unfreezing; washing; scaling off; degreasing; grinding; enzymolyzing; separating; de-oiling; ultra filtering; condensing; spray-drying; getting the product. This invention possesses simple craft and short production circle.

Description

technical field

[0001] The invention relates to a high-purity fish collagen peptide industrial product, the protein content of which is above 85%, and the molecular weight of 90% of the fish collagen peptide is below 1000 Dalton. The invention also relates to limited enzyme-catalyzed hydrolysis of fish bone and fish skin collagen to produce fish collagen peptide powder, which can be used as a raw material for health food, general food and cosmetics. The invention also relates to a method for industrial production of the fish collagen peptide. Background technique

[0002] Collagen is an important component of the cell matrix and plays a role in bonding cells. In the human body, it mainly exists in the skin, muscles, bones, teeth, internal organs and eyes. Collagen is an important functional protein, which is closely related to cell proliferation, differentiation, exercise, immunity, joint lubrication, wound healing, etc. Due to the special functions...
