Abstract: In order to establish a clean production process of fish gelatin, the ultra-high pressure-assisted extraction of gelatin from fish skin was investigated to explore the effects of ultra-high pressure treatment pressure, ultra-high pressure treatment time, extraction temperature and extraction time on gel strength and yield of gelatin. Results indicated that the optimal extraction processing conditions were ultra-high pressure treatment pressure of 300 MPa, ultra pressure treatment time of 10 min, extraction temperature of 50-60 ℃ and extraction time of 4 h. Under the optimal extraction conditions, the gel strength and the yield of gelatin were 274 g and 75.03%, respectively. The melting and gelling temperatures were 23.6 ℃ and 16.4 ℃, respectively.

Key words: ultra-high pressure, fish gelatin, gel strength, yield
