摘要: 以只接种灰霉孢子自然发酵和接种灰霉孢子不同时间后接种D24酵母双菌发酵为处理,以单独接种D24为对照,研究灰霉对酒精发酵的影响;同时对感官评价最好的处理(接种灰霉孢子72h后接种D24)与对照的葡萄酒成品采用气相色谱-质谱联用技术,分析葡萄酒中的挥发性成分,比较灰霉接种对葡萄酒中挥发性物质的影响。结果表明:接种灰霉对酒精发酵有一定的抑制作用;两个GC-MS测试样品分别检测出47、43种挥发性成分,各占总峰面积的99.20%、99.31%,相对含量存在明显差异。

Abstract: The effect of Botrytis cinerea spore inoculation on fermentation dynamics of wine were studied by inoculating Botrytis spores alone or together with commercial yeast D24 after different intervals, the sole inoculation of D24 as the control. The volatile compounds in the best sensory evaluated treatment (72 h interval between botrytis and yeast inoculation) were analyzed by gas chromatography-mass spectrometry and compared with the control. The results showed that B. cinerea spore inoculation has a negative effect on alcoholic fermentation; In the best treatment and the control sample, 47 and 43 kinds of volatile components are detected as 99.20% and 99.31% of the total peak area respectively, and the relative contents of volatile compounds have significant differences.
