Difference Analysis of Volatile Chemical Compound Contents in Tobacco Strips of Different Size after Threshing

The difference of volatile chemical compounds in tobacco strips of different size were investigated in order to provide a reference for exploring the effect of strip structure on cigarette chemical compounds and sensory quality. Threshed strips were screened using a blade vibratory separator. Volatile chemical compound contents of different size strips were determined. Single factor variance analysis and intuitionistic analysis were conducted. The results showed that, for procured tobacco in the same grade, when the size of threshed strips changed from large to small, total contents of volatile organic acids and volatile aroma compounds showed an increase trend. There was a significant difference in the chemical composition of tobacco leaves with different sizes after threshing. Therefore, the distribution uniformity of different sizes strips has an important effect on the stability of the final cigarette quality.
