Abstract:
The scent styles of tobacco grown in 4 different ecological areas were studied by tobacco leaf aroma index proposed by Li Zhanghai et al, supplemented by sensory verification method. The results showed that, within the range of sampling of this study, tobacco grown in Yunnan Dali belongs to the typical fresh aroma type, in Fujian Nanping belongs to Fujian type of fresh aroma, in Shandong Weifang belongs to the neutral aroma type, and in Henan Pingdingshan Luzhou belongs to the typical rich aroma type. The aroma indexes in different ecological areas were mainly affected by the variation of the contents of Solanone, damascenone, isovaleric acid and dihydrokiwifruitlactone. Different ecological conditions are decisive factors, annual changes of meteorological conditions are important influencing factors of tobacco leaf aroma styles, with tobacco varieties also having certain effects on aroma styles.
