摘　　要：This study was performed to optimize the conditions for concentrating protein in commercial rapeseed meal by ultrasonic-assisted alcohol washing method. The effects of sonication time,particle size,ultrasonic power and liquid to solid ratio on protein content were investigated. The result showed that the optimal conditions for concentrating protein in rapeseed meal were: sonication time of 40 min,particle size of 40 mesh,ultrasonic power of 800 W and liquid to solid ratio of 9∶ 1. Under these conditions,the protein content in rapeseed meal was increased to 55. 47%,which was 10. 43% higher than that in rapeseed meal not treated by sonication.This study was performed to optimize the conditions for concentrating protein in commercial rapeseed meal by ultrasonic-assisted alcohol washing method.
