| Abstract: | The technical parameters of protein extracting from industrial sesame cake by means of alkaline proteinase method extraction were established. After single factor tests and orthogonal test,the optimum parameters of alkaline proteinase method were as follows: hydrolysis time 45 min,p H9,hydrolysis temperature50℃,enzyme does 4000 U / g,solvent / meal ratio 20∶1,and the extraction rate of sesame cake protein was 80.12%.The content of sesame cake protein was 67.89%. |
