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 consumpti

Embodiment 1

[0031] Embodiment 1, a fish scale collagen production process is to put 100 kg of fish scales into the reaction tank, add 1000 kg of water, add 70 kg of industrial grade hydrochloric acid, stir and react for 8-16 hours, control the pH value below 2.0, and after the specified time , put the acid water into the pool, wash the fish scales with water, drain the water in the fish scales, then add 1000kg of water, add 20kg of hydrochloric acid, stir and react for 2-12 hours, then put the acid water into the pool, rinse with water Wash the fish scales; add water to the washed fish scales, adjust the pH to 7.0-7.5 with NaOH solution, and wash with water; add 1000kg of purified water to the washed fish scales, wash the fish scales, heat up and boil for 30 minutes; reduce the temperature to 55- 65°C, control pH6.5, add 1kg of biologically active enzyme, the pH range of the biologically active enzyme used is 4.0-9.5, and the temperature range is 40°C-70°C. This example uses neutral protea...

Embodiment 2

[0032] Embodiment 2, a fish scale collagen production process is to put 100 kg of fish scales into the reaction tank, add 200 kg of water, add 50 kg of industrial grade hydrochloric acid, stir and react for 8-16 hours, control the pH value below 2.0, and after the specified time , put the acid water into the pool, wash the fish scales with water, drain the water in the fish scales, then add 200kg of water, add 5kg of hydrochloric acid, stir and react for 2-12 hours, then put the acid water into the pool, rinse with water Wash the fish scales; add water to the washed fish scales, adjust the pH to 7.0-7.5 with NaOH solution, and wash with water; add 150kg of purified water to the washed fish scales, wash the fish scales, heat up and boil for 30 minutes; reduce the temperature to 55- 65°C, control pH6.5, add 0.1kg compound protease Flavorzyme500L, enzymatic hydrolysis for 1-4 hours, after enzymatic hydrolysis, raise the temperature to 70-90°C, keep warm for 30 minutes; cool the so...

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...
