| 摘 要： | 主要以玉米粉,大米粉和豆渣粉为原料,用双螺杆挤压机进行挤压膨化,通过单因素试验和正交试验研究了螺杆转速、机筒温度、物料水分对提高产品可溶性膳食纤维含量及感官品质的影响。实验结果表明:在基础配方大米∶玉米=1∶3,豆渣的添加量8%的情况下,最佳挤压工艺条件为螺杆转速850 r/min,机筒温度150℃,物料水分14%。

| Abstract: | Corn flour,rice flour and soy bean dregs were mixed and extruded by double screw extruder.The effect of rotary speed of screw,temperature of cylinder and material moisture on soluble dietary fiber(SDF) content and the quality of appearance and taste was studied.The result showed that for the basic formula,i.e.rice flour:corn flour1:3,and 8% bean dregs,the optimal technological conditions were the rotary speed of screw 850 r/min,the temperature of cylinder 150 ℃ and the material moisture 14%. |
