| Abstract: | Gelatin is isolated from chromium-contain leather waste under mild alkaline conditions. The orthogonality design experiment was carried out, and optimum process parameters were presented. The result shown that the effect of reaction temperature on the quality and yield of hydrolyzed protein products is the largest, and the effect of enzyme is the least, other parameters effect is little. The yield of product increases, with reaction temperature increasing, but the quality of products decreases. |
