摘　　要：以不锈钢膜分离所得蔗汁为原料,考察可发酵性糖、pH值及接种量对蔗汁酒精发酵过程的影响规律,对蔗汁发酵液进行了初步分析及感官评价。结果表明:经不锈钢膜径为0.02 um分离得到的蔗汁,浊度值可降至0.4 NTU,在可发酵性糖含量为16%、初始pH值为4.5、接种量为8%及28℃的条件下培养发酵7天,酒精度可达到9.9%(体积分数)。发酵酒体黄酮类物质留存率在99%以上,具有很好的自由基清除能力;酒体具有特殊的甘蔗香味,色泽为棕黄色,澄清透亮,微量胶体沉淀悬浮物,入口醇厚。可为甘蔗汁发酵生产高品质营养型甘蔗果酒饮料提供技术参考。The effect of fermentable sugar,pH and inoculation amount on alcohol fermentation process of sugarcane juice was investigated,and the fermentation liquid of sugarcane juice was analyzed and evaluated.The results showed that the turbidity value of the juice separated by stainless steel membrane diameter of 0.02 um could be reduced to 0.4 NTU,and the alcohol content could reach 9.9%under the conditions of fermentation with fermentable sugar content 16%,pH 4.5,inoculation amount of 8%and 28℃for 7 days.The retention rate of flavonoids in fermented wine body was more than 99%,and it had good free radical scavenging ability.The wine has a special sugarcane aroma,brown color,clear and bright,trace colloidal precipitate suspended matter,mellow inlet.It can provide technical reference for sugarcane juice fermentation to produce high quality nutritive sugarcane fruit wine.
