Abstract:To explore the surface color characteristics of different flavor types of flue-cured tobaccos, the surface color of different parts of three flavor types of flue-cured tobacco from 14 provinces were conducted quantitative analysis using L* a* b* C* color space characterization method.The results were as follows.(1) The reddishness (a*) of surface color had greater variation degree in strong flavor and neutral flavor type tobacco, and the changing amplitude of surface color saturation (C*) of neutral flavor type tobacco was larger than those of strong flavor and light flavor types.(2) The rightness (L*) of surface color of neutral flavor type tobacco was the largest, and the rightness of upper leaves and lower leaves were significantly higher than those of light flavor type tobacco.The reddishness (a*) of lower leaves of light flavor type tobacco was significantly higher than those of strong flavor and neutral flavor type.The surface color saturation (C*) in different flavor type tobaccos did not have significant difference.(3) For the same flavor type tobacco, the rightness (L*) of surface color of lower leaves was the highest, that of upper leaves was the lowest, and there were significant differences among different parts.Similarly, the reddishness (a*) of surface color of upper leaves was the highest, and that of lower leaves was the lowest.(4) There were highly significantly negative correlations between reddishness (a*) and yellowness (b*) or color saturation (C*) in strong flavor type tobacco, while the correlations in light flavor and neutral flavor type tobaccos were small.
