摘要: 为验证优化酿造工艺对提高桑葚酒风味物质的有效性,本试验探究了改变发酵方式、发酵温度、果胶酶种类以及皮渣分离时间对酒体香气成分、多酚、色度及抗氧化活性的影响。结果表明: 使用GC果胶酶在16~20 ℃下进行果浆发酵,皮渣分离时间3~5 d时,桑葚酒的品质最佳。气质分析结果表明,16 ℃果浆发酵的桑葚酒中,香气物质共检测出120余种,醇类和酯类的比例接近29∶38。桑葚酒香气成分丰富、果香浓郁而复杂。电子鼻试验结果表明,16 ℃果浆发酵的桑葚酒与20 ℃和24 ℃发酵的桑葚酒香气风味区分明显。20 ℃与24 ℃发酵的桑葚酒香气风味特征差异性很小。

Abstract: In order to verify the effectiveness of optimal brewing technology in improving the flavor of mulberry wine, this experiment investigated the effects of changing fermentation method, fermentation temperature, pectinase type and separation time of peel residue on aroma composition, polyphenols, chroma and antioxidant activity of mulberry wine. The results were as follows: the best quality of mulberry wine was obtained when GC pectinase fermented fruit pulp at 16-20 ℃ and the separation time of skin residue was 3-5 days. The results of temperament analysis showed that more than 120 kinds of aroma substances were detected in the fermented mulberry wine at 16 ℃, and the proportion of alcohol and ester was close to 29∶38. The mulberry wine is rich in aroma components with rich and complex fruit aroma. The results of electronic nose experiments showed that the aroma and flavor of mulberry wine fermented at 16 ℃, 20 ℃ and 24 ℃ were significantly different. The aroma and flavor characteristics of fermented mulberry wine at 20 ℃ and 24 ℃ showed little difference.
