method to increase collagen yield, and collagen prepared using the same

摘要

This invention relates to a method of increasing collagen yield and to the collagen thus prepared, wherein the method, suitable for sterilizing animal-derived tissue by radiation irradiation without collagen denaturation and simultaneously increasing the yield of collagen. collagen, includes sterilizing animal derived tissue by radioactive irradiation, washing and spraying sterile animal derived tissue, separating collagen by reacting the pulverized tissue with an acidic or enzymatic solution, extracting collagen by addition salt, and remove the salt from the separate collagen, and furthermore, in which animal derived tissue is irradiated with radioactive rays to thereby remove microorganisms and endotoxins from it, thereby increasing the possibility of preservation and yield of collagen without denaturing the collagen. collagen, whereby the quality and reliability of collagen can be dramatically improved to meet diverse user needs, ultimately achieving improved product viability.
