| Abstract: |
| From the appearance quality，chemical components，neutral aroma components and smoking
quality，comparative analysis on the quality of Yunnan tobacco and Zimbabwe tobacco was researched. On
the aspect of appearance quality，the color of Zimbabwe tobacco was deeper than that of Yunnan tobacco，
and its identity was slightly thicker and oil sense was more strong，other aspects were equivalent. In chemical
components，the total sugar content，the ratio of sugar to nicotine and the ratio of nitrogen to nticotine of Zimbabwe
tobacco were significantly lower than those of Yunnan tobacco，and the ratio of potassium to chlorine was
significantly higher than that of Yunnan tobacco，the ratio of sugar to nicotine of Yunnan tobacco were relatively
high，basically at around 12，the ratio of sugar to nicotine of C2F grade tobacco in Kunming was 15.25，and the
ratio of sugar to nicotine of Zimbabwe tobacco was about 7. In the aspect of neutral aroma components，some aroma
components of Zimbabwe tobacco were high，and some aroma components of Yunnan tobacco were high，but the
total amount of neutral aroma components in Zimbabwe tobacco（ 239.48-266.29 μg/g ） was significantly higher
than that in Yunnan tobacco（ 207.43-222.77 μg/g ）. In the aspect of smoking quality，the aroma of Zimbabwe
tobacco was coke sweet flavor，the aroma of Yunnan tobacco showed sweet and sweet flavor，and the total scoreof sensory evaluation was not obviously defferent. In general，the quality level of Yunnan tobacco and Zimbabwe
tobacco was relatively close，the quality of style was different. In order to compensate for the lack of quantity of
Zimbabwe tobacco，Zimbabwe tobacco substitute test found it was difficult to achieve the desired effect of only
using Yunnan tobacco，but it was better that tobacco blending module in Yunnan，Guizhou，Hunan and Zambia
tobacco was substitute for Zimbabwe tobacco. |
