Technical Field
The invention relates to the technical field of removal of harmful ingredients in smoke, in particular to a composite filter tip for adsorbing crotonaldehyde in cigarette smoke and a cigarette.
Background
The sensory quality evaluation of the cigarette by the smoker is carried out by evaluating the comprehensive reflecting effect of the smoke generated after the cigarette is burnt, namely, the aroma components in the smoke generated after the cigarette is burnt, on the feeling of the smoker. The function of the oral cavity during smoking evaluation is to judge the irritation (pungency degree) of the smoke, roughness or fineness, hardness or softness of the smoke, thickness or lightness of the smoke, plumpness and aftertaste of the smoke. The cigarette evaluation depends on the throat, and the throat has the functions of judging the irritation of smoke (when the smoke flows to the front edge of the throat) and the strength of the smoke (when the smoke passes through the throat).
The sensory quality of the cigarettes is closely related to the types and concentrations of chemical components in smoke, the taste is also related to the threshold value of the chemical components, the types of compounds distributed in gas phase and particle phase substances of aerosol of the smoke of the cigarettes are thousands, and the compositions and the contents of the compounds have important influence on the sensory quality of the cigarettes. Some cigarettes often generate unpleasant sour taste, bitter taste, spicy taste, astringent taste and the like, researches show that volatile carbonyl compounds, phenolic compounds, ammonia and other substances with low molecular weight in smoke have stimulating effect, non-volatile organic acids have strong spicy, burning and rancidity smell at higher concentration, and the substances not only stimulate taste acceptance and sensory nerves of oral cavity, but also stimulate sensory nerve endings and have negative effect on the sensory quality of the cigarettes. Crotonaldehyde has a special irritant-like smell, and reflects that stronger irritation and obvious offensive odor can appear on the sensory quality of cigarette mainstream smoke.
With the change of the habit of smokers, cigarette products with lower irritation, mellow taste and clean aftertaste are increasingly popular with consumers, and therefore, how to reduce the content of crotonaldehyde in the cigarette smoke becomes a hot point of the current research.

The crotonaldehyde has suffocation pungent smell when the concentration is higher, and reflects that stronger irritation and obvious offensive odor can appear on the sensory quality of the mainstream smoke of the cigarette, which is consistent with the sensory quality evaluation result of the cigarette, and the irritation of the cigarette adopting the functional composite filter stick is reduced, and the offensive odor and aftertaste are superior to those of a control cigarette. By combining the sensory evaluation result of the cigarettes, the use of the functional composite filter stick can obviously reduce the irritation and the miscellaneous gas of the smoke, improve the comfort of the oral cavity and totally does not influence the integral fragrance quantity and the style characteristics of the mixed type cigarettes.
Although the invention has been described in detail hereinabove by way of general description, specific embodiments and experiments, it will be apparent to those skilled in the art that many modifications and improvements can be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
