以广东云浮优质成熟桑葚为原料,对桑葚果酒发酵工艺进行研究,通过正交试验及感官品评和理化指标检测,确定其最佳生产工艺为:将桑葚破碎后添加70 mg/L的果胶酶进行酶解浸渍,酶解温度25℃,时间10 h,酶解完成后,添加600 mg/L的M06酵母在20℃下进行发酵,48 h后进行清汁分离,并按要求补加糖分后继续发酵,使其最终酒度为12%vol。最后经澄清、冷冻、除菌过滤、包装后得到酒体丰满、酸涩适中、呈紫红色的澄清桑葚果酒。 相似文献

Effect of Cultivar,Temperature, and Environmental Conditions on the Dynamic Change of Melatonin in Mulberry Fruit Development and Wine Fermentation 下载免费PDF全文

High levels of melatonin have been reported in various foods but not in mulberry or its wine. This study investigated the dynamic changes of melatonin levels during mulberry fruit development and ethanol fermentation of 2 different colored mulberry cultivars (“Hongguo2? Morus nigra, black and “Baiyuwang? Morus alba, white) at 2 fermentation temperatures (16 and 25 °C). Our results showed that the melatonin level increased in the beginning of mulberry development but decreased in the end. The MnTDC gene expression level correlated with melatonin production, which implied that TDC may be the rate‐limiting enzyme of the melatonin biosynthetic process in mulberries. During mulberry fermentation, the melatonin concentration increased rapidly in the beginning and then decreased gradually. Low temperature delayed the melatonin production during fermentation. A relatively high level of melatonin was found in “Hongguo2? compared with “Baiyuwang? during fruit development and fermentation. The variation of melatonin correlated with the ethanol production rate, suggesting that melatonin may participate in physiological regulation of Saccharomyces cerevisiae during the fermentation stage. 相似文献
