中文摘要: 以裸燕麦粉和玉米淀粉为原料,采用DSE-30双螺杆挤压膨化机,进行了生产挤压膨化食品的技术研究。螺杆转速设定为25 Hz,喂料速度40 g/min,选用直径为5.0 mm的模口进行测试,以膨化度、质构特性、吸水性指数、水溶性指数等为指标,采用感官评价和综合评价方法,通过正交试验发现:物料加水量4%、IV区膨化温度180℃、燕麦与玉米淀粉物料质量比4∶6具有较好的膨化和物性效果。
Abstract:In this paper,naked oat flour and corn starch as raw material,using DSE-30 twin screw extruder,tostudythetechnologyofproducing extrudedfood.The screw speed was set to 25 Hz,feeding speed was 40 g/min,and the die with diameter of 5.0 mm was selected,the methods of puffing degree,texture characteristics,water absorption index,water solubility index,sensory evaluation and comprehensive evaluation method were used,through orthogonal test,it was found that the adding amount of water 4%,IV area puffing temperature of 180℃,the mass ratio of oat and corn starch was 4∶6 had better expansion and physical properties.
