    摘要:

    現(xiàn)有紅葡萄酒顏色特征的表征方法,,很難形象地描述和傳遞葡萄酒顏色信息?;贑IELAB色空間,,構(gòu)建了高清色彩平面(L*=60),以紅葡萄酒顏色的彩度分布圖,、明度分布圖和特征顏色圖,,并結(jié)合可見吸收光譜圖,直觀地表征紅葡萄酒的顏色特征,。采用該方法和傳統(tǒng)的CIELAB參數(shù)分析法,,對(duì)我國(guó)各產(chǎn)區(qū)10款陳釀型赤霞珠干紅葡萄酒顏色特征的研究表明,該方法可以完整而直觀地呈現(xiàn)CIELAB參數(shù)信息,,并可給出具體的酒樣特征顏色,;供試酒樣間顏色特征差異顯著,但都存在顏色過(guò)快老化的問(wèn)題,。

    Abstract:

    The existing methods of color representation are seldom reported to vividly describe and transmit wine color information. A new method was proposed to visually represent red wine color employing charts of colorfulness distribution, lightness distribution and feature color, as well as the visible absorption spectrum of a wine. A highdefinition color plane determined by a* and b* axes when L*=60 was rendered in the CIELAB color space. The colorfulness distribution chart, carrying information of a*, b*, chroma and hue, was yielded when a* and b* color parameters of a wine were projected on this plane. The lightness distribution chart, indicating the light and shade degree of a wine, was rendered according to the L* value. The feature color chart, illustrating the true color of a wine under the condition of natural observation, made a comprehensive consideration of the effects of L*, a* and b* parameters. A comparative trial of the new visualized method and a traditional analysis of the CIELAB parameters was carried out to describe the color of 10 Vitis viniferaL.cv. Cabernet Sauvignon wines from representative regions of China. The results showed that the new method presented the CIELAB parameters information completely and visually, and it also exhibited a specific feature color for each red wine impressively. There were significant differences of the charts of colorfulness distribution, lightness distribution, feature color and the visible absorption spectra between the wine samples. Besides, all wine samples encountered a problem that the color aged faster than expected.
