| Abstract: | The influencing factors on the extraction of the gelatin from Basa fish skin, including the concentration and treatment time of H_2SO_4, the ratio between powder and water, the extraction time and temperature. Based on the single factor experiment and orthogonal experiment the authors established the optimum gelatin extraction conditions from Basa fish skin were the 1%H2SO4 pretreatment for 12 hours, the extraction time 4h and temperature 50 ℃. The ratio between powder and water was 1:6, the yield under this condition was 75. 15%, and 3. 66 mPa·s viscosity, 234 g gel strength. |
