Canonical correlation analysis between main chemical components and sensory quality of the flue-cured tobacco grown in Jiangxi Province

We discussed the correlation between main chemical components and sensory quality of the flue-cured tobacco grown in Jiangxi Province. The chemical components and sensory quality play key roles in determining the quality of flue-cured tobacco. Seventy-one flue-cured tobacco samples which came from Jiangxi province were analyzed using simple correlation analysis and canonical correlation analysis. The result showed that the nicotine, total sugar, reducing sugar and the ratio of total sugar to alkali all had a close relationship with the tobacco momentum, excitant, aftertaste and concentration. The total potassium and total chlorine had a great effect on the tobacco aroma quantity and concentration. In conclusion, the chemical components had a close relationship with sensory quality of flue-cured tobacco. The acid-base balance decided the nicotine, total sugar, reducing sugar and the ratio of total sugar to alkali and the combustibility decided the aroma quantity and concentration of flue-cured tobacco.
