Description

A cigarette and its preparation method

Technical Field

The invention belongs to the technical field of novel tobacco products, and in particular relates to a cigarette and a preparation method thereof.

Background Art

Traditional cigarettes are smoked by burning the cigarette stick, which can produce smoke and release nicotine. However, since the burning of cigarette paper and tobacco produces the aroma of tobacco, it is accompanied by the production of high-temperature cracking products such as free radicals, which can easily cause damage to the body.

In order to reduce the health impact of tobacco products, especially traditional cigarettes, traditional cigarettes can be improved by ventilation dilution and adding functional materials (such as activated carbon); non-combustion methods can also be used to reduce the production of high-temperature cracking products such as free radicals from the root, such as electronic atomizers, oral cigarettes, heated tobacco products, etc. Among them, heated tobacco products are more promising because they are mainly tobacco and have a taste similar to traditional cigarettes. In recent years, their market share in Japan, South Korea, and Europe has increased rapidly.

Among heated tobacco products, due to different heating methods, they can be divided into electric heated tobacco products, atomized heated tobacco products, carbon heated tobacco products, etc. Both electric heated tobacco products and atomized heated tobacco products require matching heating appliances, such as IQOS, Ploom Tech, etc. Although carbon heated tobacco products are closest to traditional cigarettes, such as Eclipse and Teeps, which produce smoke by igniting the carbon source at the end, heating the atomized tobacco; however, carbon heated tobacco products are not easy to ignite because the carbon source must be heated to a certain temperature before ignition, and the carbon combustion produces odor. After combustion, the temperature of the carbon source is high and it is easy to ignite other substances. Therefore, the current market acceptance is not high.
