不同类型及品种烟草特有亚硝胺含量的分析
Analysis of TSNA Contents in Tobacco Leaves of Different Types and Cultivars
摘要
Abstract
In order to investigate the differences of TSNA contents among different tobacco types and cultivars, the TSNA contents in burley, sun-cured and flue-cured tobacco leaves were analyzed by GC-MS/MS before and after curing. The results showed that: 1) The TSNA contents in all samples significantly increased after curing. The average TSNA content in burley leaves was the highest either before or after curing, while that in sun-cured leaves were the lowest. Significant differences of TSNA contents were found between different cultivars of the same type, the coefficient of variation (CV) of TSNA contents among cultivars of burley tobacco was the highest, that of sun-cured tobacco was the lowest. 2) The TSNA contents in green (before curing) leaves of some cultivars were found significantly higher than those in cured leaves of some other cultivars, and a significant positive correlation was observed between the TSNA contents in green and cured leaves. Therefore, the TSNA contents in green leaves could be used as an evaluation index for screening tobacco cultivars with low TSNA contents.关键词
