Using shark cartilage as raw material, the optimal enzymatic preparation process of collagen was optimized through single factor and response surface experiments, and the structure and stability of the prepared collagen were analyzed. The results showed that the optimal conditions of extraction collagen were as follows: 9 150 U/g of pepsin, 39.85 hours of extraction time, pH 1.67, and a ratio of 1: 15 (g/mL). Under these conditions, the extraction rate of collagen was (85.09±0.17)%, and the prepared collagen retained a relatively …
