摘要: 为提高低温挤压膨化小麦辅料麦汁收得率, 优化糖化工艺,对水料比、辅料比、50℃蛋白质休止时间、62℃糖化时间、70℃糖化时间5因素进行BoxBehnken中心组合试验设计,用响应曲面法分析各参数对麦汁收得率的影响。试验得到的最佳糖化工艺参数为: 水料比416(V/m),膨化小麦比例为310%,50℃蛋白质休止时间50 min,62℃糖化时间50 min,70℃糖化时间30 min,在上述条件下,麦汁收得率可达6971%。

Abstract: In order to optimize the mashing procedures to increase the yielding rate of wort made from extruded wheat, the effects of parameters including water/grain ratio, the content of extruded wheat, duration of protein interregna at 50℃, saccharification time at 62℃ and 70℃, respectively, on yielding rate of wort were analyzed by the BoxBenhnken central combination design and response surface methodology. The mashing procedures were optimized as follows: the water/grain ratio was 416(V/m), the content of extruded wheat was 310%, the protein interregna time at 50℃ was 50 min, and the saccharification time at 62℃ and 70℃ was 50 and 30 min, respectively. Following the above optimized procedures, the yielding rate of wort could reach 6971%.
