Spatial Distribution of Tar Content in Flue-cured Tobacco in Henan Tobacco Growth Regions and its Smoke Quality Characteristics

In order to better understand the spatial distribution of tar release of flue-cured tobacco in Henan and its smoke quality characteristics, flue-cured tobacco leaf samples were collected from tobacco producing areas in Henan province, and tar release was determined and smoking quality was quantitatively assessed.The results showed that tar of Henan flue-cured tobacco ranged from 16.0 to 22.0 mg/cig, and the cumulative frequency distribution was 89.19%.Tar release of flue-cured tobacco in south of Henan Province was generally higher than that in west Henan and central Henan.Tar release of flue-cured tobacco in west Henan was the lowest.Tar release had a significant difference between different areas.Kriging map indicated that tar release increased from west to middle south.The higher tar release of flue-cured tobacco has a higher score of aroma quality and aroma volume, while the lower tar content of flue-cured tobacco, its after-taste has a relatively high score.Henan tobacco-growing areas can be divided into the high tar release and low tar release area.
