| 摘 要： | 为了研究挤压大麦啤酒辅料中的抗性淀粉含量,试验研究了啤酒辅料的挤压蒸煮系统诸参数(模孔孔径、套筒温度、物料含水率、螺杆转速和螺杆末端端面至模板内表面的距离),采用五因素五水平1/2实施的二次正交旋转组合设计,建立数学模型研究表明,适当的挤压参数可以减少大麦辅料中抗性淀粉含量。

| Abstract: | To reduce the content of resistant starch,laboratory researches were carried out on the parameters of extrusion system,for example,diameter of die nozzle,barrel temperature,material moisture,screw speed and the distance between screw end and template inner surface.To acquire the best parameters,the method of five-factor and five-level quadratic orthogonal rotating combination design was applied,and 36 extrusion barley samples were acquired.By application of the American Cereals Association measuring method,the content of re-sistant starch in barley extrusion expansion was measured to find out the rules that how extrusion system para-meters had influenced the resistant starch in barley.Researches indicated that appropriate extrusion parameter could greatly decrease the resistant starch in barley. |
