Abstract:

To study the relationship between chemical composition and sensory quality of tobacco leaves of Yimeng hilly ecological region with honey sweetness and burnt flavor, 176 flue-cured tobacco samples from tobacco-growing areas of Weifang, Rizhao and Linyi in Shandong Province were selected as typical representative samples, including lower tobacco leaves X2L, X3L, X2F and X3F; middle tobacco leaves C2F, C3F, C2L and C3L; upper tobacco leaves B2F, B3F, B2L and B3L, and the conventional chemical compositions and sensory quality indexes were statistically analyzed. Simple correlation analysis showed that tobacco combustion had significantly negative correlation with total nicotine and extremely significantly negative correlation with the difference between total sugar and reducing sugar, and significant or extremely significant positive correlation with starch, reducing sugar and potassium. In addition, the ash content had significantly negative correlation with reducing sugar, chlorine and the difference between total sugar and reducing sugar, and extremely significantly positive correlation with starch. Irritation was significantly negatively correlated with chlorine. The canonical correlation showed that total nicotine was positively correlated with concentration and smoking strength. Nitrogen/nicotine was negatively correlated with concentration and smoking strength. Chlorine was negatively correlated with irritation and aftertaste. Therefore, total nicotine, nitrogen content and chlorine content are the key factors affecting the sensory quality of flue-cured tobacco in Yimeng hilly ecological region.

Key words: hilly ecological region of Yimeng, flue-cured tobacco, conventional chemical composition, sensory quality, simple correlation analysis, canonical correlation analysis
