Abstract: In order to provide methodological support for the compatibility analysis of tobacco leaves, a sensory evaluation method was developed by referring to known tobacco sensory evaluation methods. The developed method consisting of evaluation items, scoring rubrics, evaluation requirements and result expression could comprehensively and quantitatively evaluate the compatibility of tobacco leaves with four first-level indexes, including prominence, promotion, improvement and integration, as well as the overall compatibility score. The compatibility between the Longjiang tobacco leaf module with different proportions and typical tobacco leaves from different production areas was analyzed using the developed method. The results showed that within the gradient range set by this experiment, there were differences and optimal proportions in the compatibility between the Longjiang tobacco module and tobacco leaves with different flavor styles from typical production areas. Longjiang tobacco leaves showed relatively good compatibility with fresh flavor leaves only when blended at a low proportion, while the optimal proportion with medium flavor leaves from Tongren, Guizhou was10%. However, the overall compatibility with robust flavor leaves was better, and the overall compatibility score increased steadily with the increase of the blending proportion within the experimental gradient range. The developed sensory evaluation method for tobacco compatibility could accurately and quantitatively describe the compatibility of tobacco leaves and provide methodological support for the design and maintenance of tobacco module blending and tobacco blends.
