Abstract

The invention discloses a method for preparing collagen protein powder from fish scales. The method comprises the following steps of: (1) deordorization, decalcification and washing treatment on the fish scales; (2) cryogenic grinding treatment on the fish scales; (3) steam explosion treatment on the fish scales; (4) enzyme hydrolysis of the fish scales; and (5) preparation of the collagen protein powder from the fish scales. The production method provided by the invention is simple, less in dosage of protease, low in production cost, short in processing cycle, mild in condition, high in utilization rate of equipment and easy to realize industrialized production, and can reach an average extraction rate of above 70%. The collagen protein content in the prepared collagen protein powder reaches above 95%, the in vitro digestibility of the powder reaches above 95%, and the problem of utilization of fish scales in fish processing is well solved, so that the additional value of leftovers in the processing of aquatic products increases, and the comprehensive utilization rate of freshwater fish is improved.

Description

technical field [0001] The invention relates to a preparation method of collagen, more specifically, relates to a method for preparing and extracting collagen powder using fish scales as raw materials. Background technique [0002] my country is a large fishery country. In recent years, with the increase of the total amount of aquaculture aquatic products and processing demand in our country, the pressure of aquatic product processing waste on the environment has become increasingly significant. Getting stronger and stronger. During the production and processing of aquatic products, fish scales, fish skins, viscera and other offals will be produced. Fish scales account for 3-5% of this part of the offals and are rich in collagen. Since the 1980s and 1990s, fish scales have been used more and more extensively as biomaterials for the repair of human organs and the manufacture of artificial organs. Contents of the invention [0003] The technical problem to be solved by the ...
