Abstract:

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.

Key words: CIELab parameters, anthocyanins, young red wine
