摘　　要：该研究以桂葡6号葡萄为原料制备葡萄酒,在发酵前分别添加辅色素槲皮素与芦丁,以不添加辅色素为对照,对不同葡萄酒基酒理化指标进行测定,并研究其在瓶储期内(1、3、6、9个月)颜色参数及花色苷含量的变化。结果表明,槲皮素组基酒酒样的总酚含量最高(0.857 g/L),pH值及总糖含量最低,其他指标无显著差异(P>0.05);瓶储结束时,该组别葡萄酒酒样的a^(*)、b^(*)、C^(*)值最佳,分别为21.11、3.16、21.38;各组酒样中均含有15种不同类型的花色苷,槲皮素组酒样花色苷总量及各类花色苷(除花色素单糖苷和酰化类花色苷外)含量在瓶储6个月时达最大值;瓶储3、6、9个月时,槲皮素组酒样花色素双糖苷、未酰化与未甲基化类花色苷占比高于对照组和芦丁组。综上所述,槲皮素在瓶储期内对酒样的辅色效果明显。Using Guipu 6 grape as raw material to prepare wine,copigments quercetin and rutin were added before the fermentation,and using the wine without copigment addition as control,the physicochemical indexes of different base wines were determined,and the changes of color parameters and anthocyanin content during the bottle storage period(1,3,6,9 months)were studied.The results showed that base wines samples of quercetin group had the highest total phenol content(0.857 g/L),and the lowest pH and total sugar content,there were no significant differences in other indexes(P>0.05).At the end of bottle storage,the a^(*),b^(*)and C^(*)values of wine samples in this group were the optimal,which were 21.11,3.16 and 21.38,respectively.There were 15 different types of anthocyanins in each wine sample.The total content of anthocyanins and all kinds of anthocyanins(except monoglycosides and acylated anthocyanins)in wine samples of quercetin group reached the maximum value after 6 months in bottle storage.After 3,6 and 9 months of bottle storage,the proportion of anthocyanin diglycosides,unacylated and unmethylated anthocyanins in wine samples of quercetin group was higher than that in control group and rutin group.In conclusion,quercetin had obvious copigment action effect on wine samples during the bottle storage period.
