摘　　要：目前葡萄酒品质评价的主要依据是人的感官品评,虽然可靠但却存在一定的主观性。在感官评价的基础上再结合仪器分析手段的评价体系构建将更有利于葡萄酒品质特征的精确评价。本研究对同一品种酿制的不同档次红葡萄酒进行了紫外可见光谱扫描,并分析葡萄酒品质与分析参数间的相关性,结果表明,200～800 nm范围的紫外-可见吸收光谱结果与葡萄酒品质具有很好的相关性。不同酿酒葡萄酿制的葡萄酒也存在差异,因此,通过进一步的技术完善,200～800 nm波长范围的紫外-可见光谱扫描结果可用于葡萄酒不同档次的辅助鉴别方法。At present, sensory tasting is still the main method in grape wine quality evaluation. Although it is considered to be a reliable approach, such subjective judgement is not perfect. Sensory tasting coupled with instrument analysis will be more accurate for wine quality evaluation. In this study, red grape wine made from the same variety of wine grape （Cabernet Sawignon） but of different quality were detected by UV-visible spectroscopy, and the correlations between wine quality and UV-visible absorption spectroscopy parameters were analyzed. The results indicated that within the range of 200-800 nm wavelength, UV-visible absorption spectrum results and wine quality had good correlations. UV-visible ab- sorption spectrum results of grape wine made from different varieties of wine grape differed from each other. Accordingly, UV-visible spec troscopy could be used as an auxiliary identification method in wine quality evaluation.
