通过感官评定发现纯酒曲和混合酒曲酿造出的米酒风味差别不是太大,当然本次实验选取了混合酒曲作花酿研究,也是试图利用不同酒曲的协同作用,优势互补,获得风味独特的低酒精度花酿饮
摘要:以合欢花的干花绒和东北圆粒糯米为原材料,对糯米酒初酒的发酵工艺条件进行了研究。并且将以上的合欢花干花以一定的工艺配制成合欢花花米酊,然后按照特定的比例与发酵后的糯米酒液进行调配。再进行单因素的试验及正交试验,通过测定总酸,总糖,酒精度以及感官风味评价等指标来确定发酵的条件,整合数据分析出合欢花糯米酒酿造的最佳工艺参数。实验结果表明,发酵前5d的总糖含量比较多,但随着发酵的不断进行,糖逐渐转化成了酒精,发酵5d之后总糖含量以及酒精度都慢慢趋于稳定。同时以水米比1:0.8、发酵温度28℃、发酵时间为5~7天、加曲量0.01%为糯米酒的初酒的发酵工艺,调配花米酊25%、蔗糖6%、柠檬酸0.3%。最终得到三款风味怡人,美容养颜,清爽开胃的功能性花酿饮料饮品。

Development of Flower Glutinous Rice Wine
Abstract: The fermentation conditions of Dongbei glutinous rice wine were studied by using dried albizia flower and glutinous rice as raw materials. And the dried albizia flowers with a certain process made of rice tincture, according to a specific proportion and the fermentation of glutinous rice wine after deployment. The optimum conditions were determined by single factor test and orthogonal test. The fermentation conditions were determined by measuring the total sugar, total acid, alcohol and sensory evaluation. The results showed that the total sugar content was more than 5 days before fermentation, but the total sugar and alcohol content became stable after 5 days of fermentation. At the same time, the ratio of water to rice was 1: 0.8, the fermentation temperature was 28 ℃, the fermentation time was 5 ~ 7 days, and the curvature was 0.01%. The fermentation process of glutinous rice wine was 25%, 6% citric acid, 0.3%. And finally get a pleasant flavor, beauty beauty, refreshing appetizer of functional flowers glutinous rice wine drinks.

1.1.1糯米酒资源概述
我国酿酒历史源远流长,在《史记》之中有记载,仪狄造“旨酒”以献大禹。早在大禹时期便有以粮酿酒之法。后经过商周,历秦汉时期,乃至唐宋年间,皆以果粮进行蒸煮,再加以酒曲发酵,压榨而后得酒。米酒是我们的祖先最早开始酿制的酒种,几千年来一直受到人们的青睐,在世界酿酒史中独树一帜,是我国传统的发酵食品。甜米酒的原料是糯米,蒸煮后再拌入酒曲发酵而成,具有丰富的营养、 口味微甜、酒精度数较低,饮后能够提神开胃, 具有舒经活络、滋阴补肾、健胃润肺、镇静安神和祛风除湿等功效[1]
