贺兰山东麓年轻红葡萄酒的CIELab颜色空间特征

采用CIELab系统方法得到宁夏贺兰山东麓年轻红葡萄酒的颜色空间参数，并研究花色苷与颜色参数的相关性。以贺兰山东麓产区2012年份不同品种的10 个年轻红葡萄酒为材料，采用紫外分光光度计和pH示差法计算得出CIELab颜色空间参数以及总花色苷含量，通过相关性分析对葡萄酒各个颜色参数和总花色苷进行研究。结果表明：不同葡萄酒样品的明度L*、红度a*、黄度b*、饱和度Cab和色调角Hab等空间参数不同，表现出不同的颜色特征；总花色苷含量在161.2～287.8 mg/L，与参数L*、a*、Cab均呈显著相关性，决定年轻红葡萄酒的明度、色度及饱和度。

Characteristic Analysis of Young Red Wine from the Eastern Foot of Helan Mountain Based on CIELab Color Space Parameters

Our present study used CIELab system to obtain the color space parameters of young red wine from the Eastern
Foot of Helan Mountain and to explore the correlation between anthocyanins and color parameters. Ten different young
red wine samples made from different grape varieties grown at the Eastern Foot of Helan Mountain in 2012 were tested.
Ultraviolet spectroscopy and pH-differential method were used to determine the CIELab color space parameters and total
anthocyanins. A correlation analysis was made between total anthocyanins and color space parameters. The results showed
that different wine samples had different color space parameters, such as L*, a*, b*, Cab and Hab, suggesting different color
characteristics. Total anthocyanin contents (TAC) were 161.2－287.8 mg/L, which showed a significant correlation with the
parameters L*, a* and Cab, and determined luminosity, hue and saturation of young red wine.
