Keywords
Pigskin, Collagen, Uv Rays
Abstract
Abstract The aim is to obtain pig skin collagen hydrolyzate with good ultraviolet absorption ability so that it can be used as a natural sunscreen material in skin care products. Using pig skin as the material, after obtaining collagen, it is preheated at different temperatures and hydrolyzed for different times by using bromelain, papain, pepsin, etc. The results showed that the obtained hydrolyzate had the best absorption capacity for short-wave ultraviolet rays, followed by medium-wave ultraviolet rays, and among the three, the pepsin group was better. Preheat 0.5% collagen at 95¡ãC for 30 minutes, and then hydrolyze it with 1% pepsin for 1 hour to obtain the best ultraviolet absorption ability.
