Abstract

The invention discloses a cigarette capable of indicating the color change in a smoking process as well as an indication method and use of the cigarette, belonging to the technical field of cigarettes. According to the method, ferric chloride hydrate is added into the cigarette, and the weight ratio of the ferric chloride hydrate to tobaccos in the cigarette is 0.05%-0.4%. According to the methodfor indicating the smoking process of the cigarette, phenols produced in the smoking process of the cigarette are authenticated by virtue of trivalent iron ions, and different colors are presented along the smoking progress, so that a customer can relatively visually feel the tar content produced in the smoking process. The method is simple, special equipment does not need to be used, and the selected materials are safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a cigarette capable of indicating color changes during smoking, an indicating method and application. Background technique [0002] Cigarettes produce smoke through combustion, and the smoke smoked by consumers is the mainstream smoke that has been intercepted by the cigarette filter. Filter is an important part of cigarettes, which can intercept tar, nicotine and other harmful components of cigarettes. [0003] According to the provisions of the national standard GB5606.5-2005 "Cigarette Part 5: Mainstream Smoke", the tar content grades and the corresponding box label tar content regulations, the tar content of cigarettes is divided into three grades: high, medium and low, among which low The corresponding amount of tar in tar cigarettes is "≤10mg". The remaining part of the particulate matter in cigarette smoke except water and nicotine is called tar. In 1990,...
