Method for manufacturing collagen from black sea cucumbers from East China Sea

Abstract

The invention relates to a method for manufacturing collagen from black sea cucumbers from East China Sea, which comprises the following steps: (1) adding Alcalase hydrolysis protease in an amount which is 0.01 to 10 percent based on the weight of black sea cucumbers from East China Sea, protamex composite protease in an amount which is 0.01 to 10 percent based on the weight of black sea cucumbers from East China Sea and flavourzyme in an amount which is 0.01 to 10 percent based on the weight of black sea cucumbers from East China Sea into the black sea cucumbers from East China Sea which are subjected to foul-removing and cleaning treatment, heating the materials to 45 to 47 DEG C, and hydrolyzing at a constant temperature of 45 to 47 DEG C with stirring for 4 hours; and (2) after enzyme hydrolysis is finished, performing fine filtration by a membrane filter, concentrating in a vacuum concentrator, keeping the temperature of the materials in the vacuum concentrator between 55 and 58 DEG C by controlling the heating steam valve of the vacuum concentrator, and concentrating to obtain pasty or powder collagen product from black sea cucumbers from East China Sea. The method has the advantages that: a technical route of combination of three enzymes and hydrolysis degree intermediate detection is adopted, so the relative molecular weight of the product of the enzyme hydrolysis of the black sea cucumbers from East China Sea can be controlled to meet the requirement on the relative molecular weight of sea cucumber collagen products; and the product of the hydrolysis product is free from bitter taste and fishy smell.

Description

technical field [0001] The invention relates to the field of utilization and processing of new marine biological resources, in particular to a method for producing collagen from black ginseng of the East China Sea. Background technique [0002] According to research, there are about 140 kinds of sea cucumbers in my country. Among them, more than 20 kinds of sea cucumbers are edible. The common edible sea cucumbers include sea cucumbers, sea cucumbers, green sea cucumbers, jade-footed sea cucumbers, plum-flowered ginseng, white anal sweet potato (Acaudina leucoprocta H.L.Clark), white ginseng, and white ginseng. Radix Ginseng, Radix Ginseng, Radix Radix Ginseng with White Background, Radix Radix Radix Ginseng, Black Milk Ginseng, Coarse Sea Cucumber, Two-color Table Ginseng, etc. The black ginseng of the East China Sea is mainly composed of wild black sweet potatoes (also known as: sea cucumbers of the East China Sea or sweet ginseng of the East China Sea). The maximum body ...

[0014] 3. At present, the main domestic species of sea cucumber - sea cucumber is expensive. In Liaoning and Shandong, the main producing areas of sea cucumber, the price of cultivated light-dried sea cucumber is 6,000-7,000 yuan per 500 grams, and the price of wild light-dried sea cucumber is even higher. 18,000-30,000 yuan per 500 grams, expensive raw material prices limit the production of sea cucumber collagen
