Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] A preparation process of fish scale collagen, comprising the steps of:

[0030] Step 1, pretreatment: In the present invention, the air-dried fish scales are used as raw materials, so the fish scales need to be rehydrated first. Therefore, in the present invention, the fish scales are first put into the water tank, and water 20 times the weight of the fish scales is added. hours; the soaking temperature is 30°C and below, and the fish scales absorb water naturally.

[0031] Step 2, decalcification: the present invention adop...

Abstract

The invention provides a preparation process of a fish scale collagen protein. With the preparation process, the collagen protein can be extracted from fish scales, so that the fish scales are changed into things of value from waste material and thorough utilization of resources is realized. The preparation process comprises the following steps of pretreating, decalcifying, neutralizing and removing impurity, washing by using water, sol, solid-liquid separating and filtering, hydrolyzing, filtering and separating the collagen protein, filtering and separating the macromolecular protein, desalting, dehydrating, drying and the like to obtain collagen protein powder. The collagen protein powder prepared by the preparation process has the molecular weight of less than 5000 Daltons and can be absorbed by the human body easily.

Description

technical field [0001] The invention relates to a production method of collagen, in particular to a preparation process of fish scale collagen. Background technique [0002] Collagen is widely used in food, cosmetics, and health products industries. The existing raw materials for collagen preparation mainly come from the bones and skins of terrestrial animals. With the rise of prices, in order to pursue the rapid growth of animals in recent years, more and more chemical additives have been added to animal feed, resulting in a significant reduction in the content of bone and skin protein peptides in terrestrial animals, and they are seriously polluted by chemical additives, resulting in the loss of peptides The source of protein is greatly affected. [0003] Fish scales are usually scraped off and thrown away as waste. In fact, fish scales are rich in protein, fat and multivitamins, as well as iron, zinc, calcium and a variety of trace elements necessary for the human body,...
