Abstract

A method for removing fat and ash from fish scales to obtain high-quality collagen includes such steps as removing impurities, pressure steaming to remove fat, washing with ionic exchanging water, and adding the fish scales to the aqueous solution of hydrochloric acid while stirring for removing ash.

Description

technical field [0001] The present invention relates to a method for degreasing and deliming fish scales, which can be used as a raw material of collagen useful as cosmetic materials, various medical biological materials, food materials, and the like. Background technique [0002] In the past, collagen used in various applications was generally extracted from mammalian collagen tissues such as cows and pigs, but since the occurrence of BSE (so-called mad cow disease), there has been a tendency to move away from collagen from mammals, especially cows , in recent years, collagen from fish has received attention. Hitherto, fish-derived collagens have been known that use the skins of marine fish such as flounder and salmon as raw materials. Collagens made of such fish skins have fish-specific odors. Considering the unsuitable odors, The compounding amount is limited, and when applied to cosmetics, etc., the effects of collagen such as moisture retention and improvement of skin ...
