[Objective] The study aimed to elucidate the effects of two kinds of organic potassium salt cigarette auxiliaries on the pyrolysis performance of cigarette paper. [Method] By adding two kinds of organic acid potassium salt with different concentrations to cigarette paper, the effects on the pyrolysis performance of cigarette paper were studied by means of simultaneous thermal analysis, mainstream smoke detection and sensory quality evaluation. [Result] With the increase of the concentration of potassium carbonate and potassium citrate, the initial temperature of thermogravimetric loss gradually decreased, and the increase of weight loss rate and weight loss in the initial heating period corresponded basically with the addition concentration. With the addition of potassium citrate in the cigarette paper, the number of smoking pons decreased gradually, and the content of nicotine and tar also decreased gradually. When the addition amount was 3 %, the release of CO was the lowest, and then increased with the increase of the addition amount. With the addition of potassium carbonate in cigarette paper increasing, the number of smoking mouthfuls firstly decreased and then increased slowly, and the content of nicotine and tar also showed a decreasing trend. When the addition amount of potassium carbonate in cigarette paper was 3.5 %, the content of nicotine in cigarette paper and the number of smoking mouthfuls were the least. When the concentration was 2.5 %, the CO content was the lowest. [Conclusion] The use of cigarette paper additives catalyzed the thermal cracking process of cigarette paper, which resulted in the decrease of tar and CO content in mainstream smoke and affected the sensory quality of cigarettes.
