  1. This table is the experimental results of Box–Behnken design and corresponding schemes. The gossypol content is selected as the response value Y. The independent variables A, B, C and D was corresponding to initial temperature, enzymatic hydrolysis time, enzyme content, and substrate moisture are shown in the table
