摘　　要：研究利用水剂法同步提取分离米糠蛋白与油脂,以米糠蛋白提取率为主要指标,通过单因素试验和正交试验优化,得到了水剂法提取的最佳工艺条件为料液比1∶12(g/m L)、p H 8.0、浸提温度45℃和浸提时间3.0 h。此条件下,米糠油与米糠蛋白的提取率分别为22.17%、54.29%。Through the research on synchronous extraction of rice bran protein and oil by aqueous method,based on the result of single factor experiment and orthogonal experiment, with the extraction yield of rice bran protein as the main index,the optimal extraction conditions by aqueous method were concluded that the solid-liquid ratio was 1∶12（g/m L）,p H was 8.0,the soaking temperature was 45℃,and the soaking time was 3.0 h. Under this condition, the extraction yields of rice bran protein and oil were 54.29% and 22.17%.
