摘要: 利用液液萃取-溶剂辅助风味蒸发、气相色谱-嗅闻-质谱联用和香气活性值(odor activity values,OAV)联合技术鉴定‘双红’(Vitis amurensis Shuanghong)干红葡萄酒游离态和糖苷结合态关键香气物质。结果表明,‘双红’干红葡萄酒游离态香气物质中有37 种物质的气味稀释因子高于8,23 种物质的OAV大于1。通过香气重构和感官定量描述性分析发现,‘双红’干红葡萄酒原酒与采用42 种香气物质重构酒样在山楂味、烟熏味/动物味、脂肪味和煮蔬菜的香气强度差异较小,而后者在生青味和黑色浆果的香气强度显著低于前者,利用香气缺失实验进一步证实了脂肪酸乙酯、β-大马士酮、C6醇类和挥发性酚类物质对‘双红’干红葡萄酒的整体香气有显著影响。

Abstract: The key free and glycosidically bound aroma compounds of ‘Shuanghong’ red wine were identified by liquid-liquid extraction-solvent assisted flavor evaporation (LLE-SAFE) combined with gas chromatography-olfactometry-mass spectrometry (GC-O-MS) and odor activity value (OAV) analysis. The results showed that 37 free aroma compounds with flavor dilution (FD) factors higher than 8, and 23 free aroma compounds with OAVs higher than 1 were identified. Based on the results from aroma reconstitution and quantitative descriptive sensory analysis, there was no significant difference in the intensity of hawthorn-like, smoky/animal-like, fatty, and cooked vegetable-like aromas between the original wine and reconstituted wine prepared by mixing 42 aroma compounds, but the intensity of green and black berry-like aromas in the latter was significantly lower than that in the former. Aroma omission tests confirmed that fatty acid ethyl esters, β-damascenone, C6 alcohols, and volatile phenolic compounds had significant effects on the overall aroma of ‘Shuanghong’ wine.

Key words: ‘Shuanghong’; aroma; gas chromatography-olfactometry-mass spectrometry; aroma reconstitution; aroma omission
