以小麦麸皮为原料制备脂肪模拟品，选用双螺杆挤压机对添加了α－淀粉酶的小麦麸皮进行挤压膨化，通过单因素实验和响应面回归分析确定了 DE 值为3．2（WBFS3．2）和8．9（WBFS8．9）的两组低DE值小麦麸脂肪替代品的制备工艺，得到双螺杆挤压的工艺条件分别为：WBFS3．2物料含水量30％，进料速度为30 g／min，螺杆转速为120 r／min，挤压温度（机头温度）为140℃，加酶量为0．5％；WBFS8．9物料含水量35％，加酶量为0．6％，其他条件与WBFS3．2的相同．

To produce fat analog products, this paper extruded wheat bran containingα-am-ylase by twin-screw extruder.Through the single factor experiment and the response surface regression analysis, determined the preparation conditions of WBFS3.2 and WBFS8.9.The former were as follows.The material contained 30%water, and the feed rate was 30 g/min. The screw speed was 120 r/min, the extrusion temperature ( head temperature) was 140℃, and enzyme dosage was 0.5%.The latter were as follows.The material contained 35%wa-ter, and enzyme dosage was 0.6%.Other conditions were the same to that of WBFS3.2.
