Abstract:

In order to reveal the relationship between the material content of plastid pigments and neutral volatile aroma components in flue-cured tobacco, with ‘Yun 87’, ‘K326’, ‘Yun 203’ and ‘KRK26’ as experimental material, the C3F grade tobacco leaves was used in the analysis of plastid pigments and neutral volatile aroma components by instrument of high performance liquid chromatography GC-MS. The results showed that the content of chlorophyll, carotenoids and their degradation products existed significant differences in different varieties. The content of total plastid pigments in ‘Yun 203’ and ‘Yun 87’ were the highest. The aroma quality of ‘YUN87’ after brewage was coordination. The aroma quality of ‘K326 ’and ‘KRK26’ were better than ‘Yun 203’. The highest proportion of degradation products of the plastid pigment was neophytadiene, the result manifest as follows: ‘Yun 87’> ‘KRK26’> ‘K326’> ‘Yun 203’.
