Abstract:

The paper aims to enrich the research on tobacco leaves of different flavor types and provide reference for the development of characteristic high-quality tobacco leaves with sweet or honey sweet flavor. 273 tobacco leaf samples from Fujian tobacco-growing areas from 2013 to 2020 were collected. Then, twenty indicators, such as starch content, appearance quality, sensory quality, etc., were determined and evaluated by using cluster analysis and correlation analysis. The results showed that the starch content of Fujian flue-cured tobacco was a little higher than the national average. Starch content of upper leaves and middle leaves were much higher than that of lower leaves. A parabolic relation was observed between the starch content and the appearance quality and sensory quality. The best appearance quality and sensory quality were found in the middle starch content group. Correlation analysis indicated that, in the low starch content group, the starch content affected the appearance quality through indicators of oil and plumpness, and affected the sensory quality through indicators of aroma flavor type, sweetness, aroma quality, aroma quantity, concentration and aftertaste; in the middle starch content group, the starch content affected the appearance quality through indicators of oil, plumpness and glossiness, and affected the sensory quality through indicators of aroma flavor type, sweetness, aroma quality, and offensive odor; in the high starch content group, the starch content negatively affected all the appearance quality indicators, and affected the sensory quality through indicators of aroma flavor type and strength. The starch content of Fujian flue-cured tobacco was relatively high and was significantly different among the samples. Too high or too low starch content will have negative effects on flue-cured tobacco quality, therefore, we should balance the starch content in production to improve tobacco quality.

Key words: Fujian flue-cured tobacco, starch content, appearance quality, sensory quality, parabolic relation
