Besides the value of the collagen polypeptide, a new way is found for the value-added utilization of fresh bones. At present, most of fresh bones are roughly processed into feed, the utilization rate of the feed for high-added-value deep processing is less than 10 percent, and the resource waste is very prominent. Therefore, the development of collagen polypeptide by using fresh bone is an 'extraction' project with great social significance.
