摘要:

以蛇龙珠葡萄为原料进行模拟实验,用红葡萄酒酵母(S 101)作对照,探索转基因酵母S.c MDC 对红葡萄酒发酵及酒质的影响。结果表明:用转基因酵母S.c MDC 发酵的葡萄酒总酸含量较低、葡萄酒的干浸出物含量、总酚含量均较高,苹果酸- 乳酸发酵提前完成。挥发酸含量、残糖含量、蛋白质含量与红葡萄酒酵母(S 101)发酵的酒质区别不大。

关键词: 葡萄酒, 转基因酵母(S.c MDC), 总酸含量, 苹果酸, 乳酸

Abstract:

In order to understand the effects of engineered yeast MDC on fermentation and quality of red wine, the fermentation of Caberbet Gernischet wine using this strain was simulated in a 2 L flat bottom flask. Saint Georges S101 served as control. Results showed that compared with the control, engineered yeast MDC-fermented wine revealed a lower total acid content and higher contents of dry extract and total phenols and the malic-lactic acid fermentation was accomplished ahead of time. No significant differences in contents of volatile acid, residual sugar and protein were observed between engineered yeast MDC and Saint Georges S101-fermented wines.

Key words: wine, engineered yeast (Saccharomyces cerevisiae MDC), total acid content, malic acid, lactic acid
