利用自选酵母酿造鸭梨酒

The Production of Pear Wine by Self-selected Yeast

利用自选产香酵母GY酿造鸭梨酒,应用正交试验对其酿造工艺进行了优化。结果表明,在鸭梨汁中添加50 mg/L的SO2既能抑制杂菌生长,又可以防止鸭梨汁的褐变;正交试验优化发酵条件为:温度25℃,接种量为1×107 cell/mL,初始pH值为4.0,该条件下发酵的鸭梨酒香气较突出,酒体较丰满,风味较好。

Self-selected yeast GY was used to produce pear wine, and the optimum fermentation conditions were determined by orthogonal test as follows： the addition of 50 mg/L SO2 could not only inhibit the growth of sundry bacteria but also prevent the browning of pear juice, fermentation temperature was at 25 ℃, yeast inoculating quantity was 1 ×10^7cell/mL, and the initial pH value was 4.0. Under the above conditions, the produced pear wine had full wine body and good taste and enjoyable aroma.
