| Abstract: | Response surface methodology （RSM）was applied to optimize the extraction process of soybean peptide from sufu. Based on single experiments, extraction temperature, solvent mass fraction, extraction time and solvent/sufu ratio were selected for Box-Benhnken central composite designing. RSM was employed to study the effect of these factors on the yield of soybean peptide. The results showed that the optimal processing conditions for the extraction technique of soybean peptide from sufu were 57 ℃ temperature, 69% of methanol concentration, the extraction time was 28 minutes, and solvent/sufu ratio was 9 ： 1. Under these optimal extraction conditions, the extraction efficiency of soybean peptide from sufu was 6.59 g /100 g （dry basis）. |
