Evaluation of different tobacco raw materials for heated cigarettes based on sensory evaluation and routine chemical composition.

To improve the heating cigarette product quality and stability, an evaluation method for tobacco raw materials used in heated cigarette was evaluated based on sensory quality and conventional components. Firstly, the similarity of sensory quality between tobacco raw materials and reference samples was calculated. Then the correlation between conventional chemical components and sensory quality of tobacco raw materials was further analyzed by grey correlation method. Again, the suitability of tobacco raw materials was evaluated based on fuzzy comprehensive evaluation and membership degree. Finally, the consistency and accuracy of the method were verified through repeated experiments and classification experiments. The results showed that total nitrogen and nicotine have a relatively high correlation with sensory evaluation indexes, while the correlation between the difference in two sugars and sensory evaluation indexes was relatively low. Total nitrogen and nicotine could be used as the main concern indexes in the evaluation of heated tobacco leaves. 22 kinds of tobacco raw materials samples could be divided into heated cigarette-oriented tobacco modules, auxiliary tobacco modules and filled tobacco modules. It has been proved that the evaluation method has good consistency and accurate classification, which can provide reference for formulation design and maintenance effectively, and has certain practical value and guiding significance.
