Method for preparing medical collagen sponge from East sea dark gensing

Abstract

The invention discloses a method for preparing medical collagen sponge from East sea dark gensing, which comprises the following steps: adding pepsase into East sea dark gensing defibrination going through dirt removing process; adding solid edible salt after the enzymolysis; salting, separating and collecting pulpy sediment, precipitating liquid, salting again, and separating; dissolving pulpy sediment by L- lactic acid, carrying out desalination process to the dissolved sea cucumber collagen liquid, adding food grade glutamine transaminase, spraying nepheloid sea cucumber collagen liquid into a mould, quick-freezing and forming the collagen liquid into collagen sponge instantly; freezing, alternating temperature and drying, and drying the material until the content of water is 1 to 3 %; withdrawing the collagen sponge, packing, irradiating, and entering the medical collagen sponge library. The method has the beneficial effects that East sea dark gensing is used as raw material to prepare the medical collagen sponge, the rich marine resource is enabled to be highly utilized, the sponge can also be used for crowd rejecting the mammal collagen, the problem of chemical residue in the product is solved, and the safety of the product is higher.

Description

technical field [0001] The invention belongs to the field of marine biological innovative medicine and new marine biological materials, and relates to a method for manufacturing medical collagen sponges from black ginseng of the East China Sea. Background technique [0002] Medical collagen sponge is a common surgical material with a wide range of uses. It is mainly used for hemostasis during surgery and to prevent mutual adhesion between tissues. It can be completely degraded and absorbed by tissues after surgery. It can induce the derivation and aggregation of fibroblasts, stimulate collagen production and arrangement, stimulate the formation of capillaries, ensure the blood supply and oxygen supply required for the growth of granulation tissue, regulate the functions of different cells, accelerate the absorption and secretion of collagen, and promote wound repair and healing , to prevent postoperative complications. Medical collagen sponges can also be further processed ...

Problems solved by technology

It is very difficult to remove this layer of dirt. It is difficult for Donghai black ginseng products to meet the national mandatory standard GB2762-2012 "National Standard for Food Safety / Pollution in Food" by conventional cleaning and cleaning with sodium hydroxide and hydrogen peroxide. Requirements of GB2733-2005 "Hygienic Standards for Fresh and Frozen Animal Aquatic Products" and NY / T1514-2007 "Green Food Sea Cucumber and Its Products" standard of the Ministry of Agriculture

From the test results of Donghai black ginseng products collected in the market, the harmful heavy metals exceed the national standard by tens to hundreds of times, which is the fundamental reason why the rich resources of Donghai black ginseng have not been effectively utilized and industrialized
