Changes of Limiting Dextrinase in Germinating Process of Malting Barley

Based on five different species of barley, the foot layer analytic method was used to examine the activity and heat-resistance of the limiting dextrinase. The study was conducted on the dynamic changes of several types of the dextrinase in barley germinating process, the effect of temperature on the dextrinase and the divergence of dextrinase in different barley variety. The probability of the dextrinase that as reference index is

加工过程啤酒大麦农药残留的变化

为评价啤酒大麦农药残留对啤酒的潜在风险,在浸麦、发芽、糖化之前通过添加定量的复合农药,分析各个工艺点的农残转移率,以评估主要工艺点对农残的作用以及农残对产品质量可能存在的影响。结果显示,在制麦过程中,洗麦、浸麦添加双氧水以及烘干都会使农残转移率显著下降;在发酵过程中,过滤以及麦汁的加热煮沸也会使农药残留明显降低。
