Abstract

The effect of H2O2 concentration,extraction temperature,extraction time on the yield and viscosity of tilapia skin gelatin extraction were studied by one-factor-at-a-time experiment and Response Surface Methodology(RSM).Results showed that the optimum conditions were: H2O2 concentration 0.07mmol/g,extraction temperature 53℃ and extraction time 4.6 hour.Under these conditions,the gelatin yield and gelatin viscosity were 87.71% and 8.90(mPa.s),respectively.

Key words： tilapia fish skin; gelatin; hydrogen peroxide; response surface methodology
