摘要
以辅料含量、加水倍数、50℃蛋白质休止时间、63℃保温时间和70℃保温时间5因素进行5水平二次旋转正交组合试验设计,研究了膨化大米辅料酿造啤酒的外加酶糖化工艺参数对麦汁过滤速度的影响。结果表明,最佳糖化工艺参数为:辅料含量为45.6%～47.2%,料水比为1∶5.0～1∶5.1,50℃蛋白质休止时间为52.9～53.5 min,63℃糖化时间为43.1～44.5 min,70℃糖化时间为31.2～31.9 min。(孙悟)
The method of orthogonal rotation combination test design of five factors （auxiUiary materials content, water addition times, protein rest time at 50 ℃, temperature preservation time at 63 ℃, and temperature preservation time at 70 ℃） and five levels was conducted to study the effects of saccharifying technical parameters on wort filtration speed by using extruded rice as auxiUiary materials in beer brewing. The results indicated that the optimum saccharifying technical parameters were as follows： auxiUiary materials content as 45.6 %～47.2 %, the ratio of raw materials and water as 1：5.0～1：5.1, 52.9～53.5 min protein rest time at 50℃, 43.1～44.5 min saccharifying time at 63 ℃, and 31.2~31.9 min saccharifying time at 70 ℃. （Tran. by YUE Yang）
