Description
Technical Field
The invention relates to the technical field of removal of harmful components in smoke, in particular to a composite filter tip for adsorbing 2-acetylpyridine in cigarette smoke and a cigarette.
Background
The sensory quality evaluation of the cigarettes by the smokers is performed by evaluating the comprehensive reflecting effect of the aroma components in the smoke generated after the cigarettes are burnt on the smokers after the smoke generated after the cigarettes are used by the smokers, namely the aroma components in the smoke generated after the cigarettes are burnt on the feelings of the smokers. The function of the oral cavity in the smoking evaluation is to judge the irritation (pungency), the roughness or the fineness of the smoke, the hardness or the softness of the smoke, the concentration or the weakness of the smoke, the fullness and the aftertaste of the smoke. Cigarette smoking is also dependent on the throat, and the effect of the throat in smoking is to judge the irritation of smoke (when the smoke flows to the front edge of the throat) and the size of the smoke stiffness (when the smoke passes through the throat).
The sensory quality of the cigarette is closely related to the types and the concentrations of chemical components of the smoke, the taste is also related to the threshold value of the chemical components, the number of the compound types distributed in the gas phase and the grain phase matters of the smoke aerosol of the cigarette is as high as thousands, and the composition and the content of the compound have important influence on the sensory quality of the cigarette. Some cigarettes often generate unpleasant sour taste, bitter taste, spicy taste, astringency and the like, and researches show that substances such as volatile carbonyl compounds, phenolic compounds, ammonia and the like with low molecular weight in smoke have a stimulating effect, and non-volatile organic acids have strong spicy, burnt and rancid smell when the concentration is high, and the substances stimulate taste receiving and sensory nerves of the oral cavity, stimulate sensory nerve endings and have a negative effect on the sensory quality of the cigarettes. The 2-acetylpyridine has special pungent smell, and can reflect the strong pungency and obvious miscellaneous gas on the sensory quality of the main stream smoke of cigarettes.
Along with the variation of smokers' habits, the cigarette products with lower irritation, mellow taste and clean aftertaste and pursuing comfort are more and more popular with consumers, so how to reduce the content of 2-acetylpyridine in cigarette smoke becomes a hot spot of current research.
