摘要
为进一步提高桑葚酒的品质,在桑葚酒陈酿过程中以温度、酸度及陈酿时间为变量进行正交试验,测定桑葚酒的总酚含量及总抗氧化能力,结果表明,随着陈酿时间的延长桑葚酒的总抗氧化能力及总酚含量均明显降低,且桑葚酒总酚及总抗氧化能力成显著的正相关,在温度为25℃、酒样酸度(以酒石酸计)为9g/L的条件下总抗氧化能力及总酚含量相对较好。
In order to make further improvement on the quality of mulberry wine, the aging process was investigated using orthogonal experiments designed temperature, total acidity and aging time of mulberry wine as variable quantity, considering the total phenol content and antioxidant activity as index. The results showed that the total phenol and oxidation resistance of mulberry wine were positively correlated, and both of them were signifi- cantly reduced as the time extension. Furthermore, the total phenol content and antioxidant activity of mulberry wine were better after aged under the condition of temperature 25℃ and acidity correspond to 9g/L tartaric acid.
