Optimization of preparation of small peptides from sesame meal by response surface methodology
In order to fully develop and effectively use sesame meal,the preparation process of small peptide from sesame meal fermented by Aspergillus oryzae was optimized by Plackett-Burman experiment,steepest ascent experiment and response surface methodology,with the content of small peptides as the index.The results showed that the optimal conditions for the preparation of small peptides were obtained as follows:mass ratio of sesame meal to bran 9∶1,inoculation amount of Aspergillus oryzae 0.01％,fermentation temperature 31.3℃,fermentation time 64.24 h,and ratio of material to water 1∶1.18.Under these conditions,the content of small peptides in the fermented samples could be up to 20.04％.Products rich in small peptides can be obtained from sesame meal fermented by Aspergillus oryzae.
