中文摘要: 以优质糯米和干桂花为原料,以干桂花添加量、加水量和发酵时间为单因素试验指标,糖度、酒精度、pH值、出酒量和感官评分为评价指标进行单因素试验,选用综合加权评分法,使用正交试验对发酵型桂花酒工艺参数进行优化。结果表明,在250 g糯米中,干桂花添加量0.75 g、加水量90 mL、发酵时间4 d,在此条件下制得的桂花酒综合评分最高。成品桂花酒糖度为33.22°Bx,酒精度为4.60%vol,pH 3.79,出酒量为320 mL。产品色泽金黄清亮、酒香浓郁,清香扑鼻、进口清甜、甜而不腻,诸味和谐,具有发酵型桂花酒的独特风味。
Abstract:By the high quality sticky rice and dried fragrans as raw materials,with dried fragrans added,water added and fermentation time as single-factor test indexes,and taked sugar degree,alcohol content,pH value,alcohol outputed and sensoried score as evaluation indexes,the single-factor test was carried out,and the comprehensive weighted scoring method was adopted to optimize the technological parameters of fermented dried fragrans wine by orthogonal test.The results showed that in 250 g sticky rice,0.75 g of dried fragrans was added,90 mL of water was added and the fermentation time was 4 d.Under these conditions,the comprehensive score of fragrans wine was the highest.The finished fragrans wine has a sugar degree of 33.22 °Bx,an alcohol content of 4.60% vol,a pH of 3.79 and a capacity of 320 mL.The product was golden and clear in color,rich in wine flavor,fragrant in smell,sweet in import,sweet but not greasy,harmonious in flavor,and unique in fermented fragrans wine.
