Related researches show that the harmful ingredients of cigarette smoke mainly come from cigarette tar, and the exposure of part of harmful ingredients can be effectively reduced by smoking low-tar cigarettes. Along with the increasing attention of people to health problems, tar and harm reduction has become a social consensus, and the demands of consumers for low-tar cigarettes are increasing, and simultaneously, higher demands are also being put on the low-tar cigarettes. Therefore, low tar cigarettes have become an important product development in the tobacco industry.

The cigarettes are used as a hobby consumer product, and consumers need to have certain physiological satisfaction, fragrance quality and comfort level when pursuing low tar. The existing low-tar cigarettes are mainly realized by adding ventilation dilution, filter material interception improvement, low-tar leaf formulation and other technologies or a combination of the two technologies. CN20162038375. X discloses a filter tip cigarette with adjustable tar content by adjusting the opening and closing quantity of ventilation holes, and CN201810622587.8 discloses a method for adsorbing CO and tar in smoke and improving the comfort level of the smoke by using plasma modified coconut carbon loaded hyperbranched lactate. The application of the method has certain effects of realizing low tar, improving the fragrance quality and the like, but the smoke is diluted and intercepted in a large proportion, the cigarette smoke has dry feel, and the physiological satisfaction of smoking and the fragrance quality are reduced. CN201410124658.3 discloses a low tar mixed expanded tobacco and its application in low tar cigarette. CN201410818751.4 discloses an improved low tar mixed cigarette. The method uses the low-tar mixed tobacco as a raw material in a leaf group formula, and plays a certain role in reducing the tar of the cigarettes. However, the special aroma style of the mixed tobacco can affect the aroma characteristics of the flue-cured tobacco, and is not accepted by most consumers. Therefore, how to maintain the flue-cured style characteristics of the cigarette products after reducing tar content, and simultaneously has a satisfying feel of considerable strength, relatively good aroma quality and comfort, is a urgent need for solving the problems in the development process of low tar cigarettes.
