Method for increasing collagen yield, and collagen prepared using same

摘要

The present invention relates to: a method for increasing a collagen yield, and collagen prepared using the same. To this end, the present invention comprises, in order to sterilize animal-derived tissue through irradiation without denaturation of collagen and simultaneously increase a collagen yield, the steps of: sterilizing animal-derived tissue by irradiating the same; washing and pulverizing the sterilized animal-derived tissue; isolating collagen by reacting the pulverized tissue with an acidic or enzyme solution; extracting collagen by adding a sa and sequentially removing the salt from the isolated collagen. The present invention removes bacteria and endotoxins by irradiating animal-derived tissue, thereby increasing preservability and increasing yield without the denaturation of the collagen, and thus the quality and reliability of collagen is remarkably improved, thereby satisfying various needs of users such that a good image can be promoted.
