Fishscale collagen production process

Abstract

The invention discloses a fish scale collagen process technology that is made up from the process of twice acid process, alkali neutralized, boiling, enzymolysis, exchanging absorbing, concentrating, filtering, drying and spraying. The invention also supplies the invention to easily produce fish scale collagen produce technology. The invention has low molecular weight, stability, and low content or ash content.

Description

1. Technical field [0001] The invention belongs to the technical field of biological extraction, and in particular relates to a fish scale collagen production process. 2. Background technology [0002] Collagen, also known as collagen, is a sugar-containing protein that is widely distributed in nature, mainly in the connective tissue of mammals, as the constituent materials of skin, bones, tendons, ligaments, and blood vessels; there are 16 About % is protein, collagen accounts for 30-40% of the total protein in the body, and is the protein with the most content in the human body; the amino acid composition of collagen is very special, of which glycine (Gly) accounts for 30%, proline (Pro) and hydroxyl Proline (Hyp) totals about 25%. [0003] Collagen peptides come from collagen and are widely used in food, cosmetics, beverages and health care products industries. Collagen peptides in traditional crafts mainly come from the skin, bones, tendons and placenta of terrestrial a...

Problems solved by technology

[0003] Collagen peptides come from collagen and are widely used in food, cosmetics, beverages and health care products industries. Collagen peptides in traditional crafts mainly come from the skin, bones, tendons and placenta of terrestrial animals; however, due to the highly infectious The impact of mad cow disease and the need for animal protection have limited the source of collagen products; fish scales are rich in protein, and the main component of protein is collagen, but the nutritional content of fish scales has been ignored by people before, especially in China. The aquatic product processing industry is regarded as garbage, not only does not fully utilize its value, but also pollutes the environment

[0004] In recent years, the utilization of fish scales has attracted attention, and the extraction of collagen peptides from fish scales has begun, mainly through four methods: high-pressure cooking, acid hydrolysis, alkaline hydrolysis, and enzymatic hydrolysis; high-pressure cooking, acid hydrolysis, and alkaline hydrolysis are traditional extraction methods. , the problem of the high-pressure cooking method is high energy consumption, which is not conducive to safe production under the condition of high temperature and high pressure, and the obtained product has a high molecular weight. The collagen peptide produced by this process is not conducive to the absorption of the human body; A large amount of acid and alkali needs to be added, which seriously pollutes the environment. The introduction of a large amount of inorganic salt increases the pressure of desalination in the follow-up work, and the molecular weight of the product is not easy to control

[0005] Enzymatic hydrolysis is a new method, which has been studied in the field of scientific research, but there are the following shortcomings: 1. The pretreatment of fish scales before enzymatic hydrolysis takes a long time and is soaked alternately with hydrochloric acid and saturated lime water; 2. The amount of enzyme added is large, and most Think that optimal enzyme amount is 3%-5%; Three, make fish scale enzymolysis thoroughly, generally exceed 5 hours, and enzymolysis time is too long; All above are unfavorable for actual production; Four, the product produced has fishy smell, bitter taste, high ash content
