Optimizing germination pretreatment conditions for extraction of soy oil and protein by aqueous enzymatic method

Germination pretreatment was used to assist extraction of soy oil and protein by aqueous enzymatic method. The optimal condition of germination pretreatment condition was determined as follows: germination temperature 26 ℃,71%humidity,43 h pretreatment time.The oil and protein extraction rate were 92.42% and 91.91% under the optimal condition.Germination pretreatment could significantly increase the oil and protein extraction rate by aqueous enzymatic method,this pretreatment had a better treatment effect than grinding and ultrasonic treatement.
