Abstract Extracted collagen is first treated through acetic acid dissolution, gamma ray irradiation, Nacl precipitation and filtering to obtain the Liquid 1 and the precipitate 1; the Precipitate 1 is then treated through above said processes and the Liquid 1 is NaCl precipitated and filtered to obtain the Precipitate 2. After repeat for several times, the precipitates are mixed to obtain mixed collagen with gradient molecular weight distribution. The mixed collagen is used in replenishing that in skin and bone and is easy to absorb owing to the stepped distribution in stomach and intestine.
