Abstract: In order to investigate the effects of organic acids on the sensory quality of cigarettes,six kinds of plant natural plant granules were selected for the determination of volatile organic acids,the determination of mainstream smoke and sensory quality of cigarettes. The results showed that,after adding the natural plant particles in the cigarette filter,the flue gas aerosol had better elution ability to some volatile benzoic acid and phenylacetic acid in the natural plant,and the content of benzoic acid and phenylacetic acid in the mainstream smoke was positively correlated with the release of benzoic acid and phenylacetic acid. To some extent, the content of volatile organic acids in natural plant particles is positively correlated with the quality of cigarette smoking. The analysis of volatile organic acids in plant particles can effectively guide the selection of natural plant particles. The particulate material provides a quantifiable screening basis. A predictive model was established between the sensory evaluation and the volatile organic acid content of 21 samples by stepwise regression analysis. It showed that the content of benzoic acid and phenylacetic acid had a better effect on the sensory quality of the cigarettes and the variability of the moisturizing sensation.

Key words: natural plant particles, volatile organic acids, cigarettes sensory quality
