Abstract

Abstract: To improve the evaluation system for chemical components of strip tobacco and clarify the chemical characteristics of strip tobacco raw materials from a certain China Tobacco Corporation as well as their correlation with sensory quality, strip tobacco samples collected during 2020-2023 were used as research materials, fuzzy mathematics and ArcGIS were applied for comprehensive evaluation of chemical component availability, and the impact of chemical components on sensory quality was analyzed. The results showed that the overall quality of strip tobacco raw materials from this corporation was good, exhibiting characteristics of unstable total sugar and reducing sugar contents as well as low potassium levels. There were significant differences in potassium content, reducing sugar, total sugar, total nitrogen and nitrogen‑alkali ratio among varieties. Compared with strip tobacco from foreign producing areas, domestic strip tobacco featured lower nicotine and chlorine contents but higher reducing sugar and total sugar contents. The chlorine content of strip tobacco in most producing areas was below 0.30%, with low-chlorine areas mainly concentrated in western China. The spatial distribution map of the Tobacco Chemical Component Usability Index (CCUI) of strip tobacco raw materials showed a decreasing trend from west to east. Chemical components mainly affected irritation, dryness, aroma quantity, permeability, smoothness, and sweetness. Regional differences existed in the strip tobacco of this corporation: Producing areas such as Yunnan and Sichuan had higher CCUI values, which were compatible with the requirements of the cigarette industry. In contrast, regions with lower CCUI values needed to focus on optimizing the contents of nicotine, potassium, and chlorine in their chemical composition to enhance applicability for cigarette formulation.
