挤压膨化可以破坏细胞壁，减少传统水酶法提取米糠油中酶种类的应用和获得较高的提油率。研究挤压膨化参数（物料含水率、挤压温度、螺杆转速、模孔直径）对水酶法提取米糠油得率的影响规律，并利用响应面法对挤压参数进行了优化。得到最优参数为：物料含水率14％、模孔直径18mm、挤压温度110℃、螺杆转速105r/min，且在只使用一种碱性蛋白酶情况下提油率达到89．61％，比蒸汽预处理复合酶提米糠油（85．76％）提高4％左右。

Extrusion can destroy the cell walls , reduce types of enzyme compared with traditional aqueous enzymatic ex-traction of rice bran oil in the traditional craft and obtain higher oil extraction rate .The study researched the effects of ex-trusion parameters ( material moisture , extrusion temperature , screw speed , die-hole diameter ) on yield of rice bran oil in extracted by aqueous enzymatic method , and applied response surface method to optimize it .Optimal parameters are material moisture 14% , die-hole diameter 18mm, extrusion temperature 110℃, screw speed 105r/min.Using only one alkaline protease-Protex-6L, the oil extraction rate reached 89.61%, higher 22%than that without extrusion .
