Description
Technical Field
The invention belongs to the field of a preparation method of a novel heating non-combustion tobacco product.
Background
Because the traditional burning and sucking type cigarette generates a large amount of harmful components such as carbon monoxide, tar and the like which are harmful to human health when the tobacco is burnt, people research novel tobacco products, such as electronic cigarettes, which replace the traditional burning and sucking type cigarette. When people smoke the electronic cigarette, atomized liquid of cigarette oil of the electronic cigarette is inhaled into a human body instead of cracking products generated by burning of the traditional cigarette, so that the harmfulness can be reduced to a certain degree. However, the electronic cigarette needs to adopt liquid tobacco tar, the heating temperature of the electronic cigarette needs to be as high as 600 ℃ to generate a good atomization effect, and the high heating temperature inevitably causes some organic matters in the tobacco tar to crack to generate hazardous substances.
With the transformation of tobacco market, tobacco products (also called low-temperature cigarettes) which are not combusted by heating are gradually popularized. The tobacco products which are not burnt by heating are characterized in that tobacco shreds are heated by a special heating source, nicotine and flavor substances in the tobacco shreds are volatilized to generate smoke to meet the requirements of smokers during heating, the heating temperature is generally not more than 400 ℃, and IQOS (electric heating smokeless tobacco product) which is a representative product in the tobacco products which are not burnt by heating is more and more widely used. Ordinary electronic cigarettes provide a feeling of being close to a real cigarette by heating the tobacco tar, while IQOS provides a feeling of being close to a real cigarette by heating the cartridge. When the two cigarettes are the same as the smoke inhaled by smokers, the main components of the smoke are less nicotine and spice generated in the heating process, the smoke does not contain tar, but the IQOS can provide the real taste which is closest to the traditional cigarette compared with the electronic cigarette with heated tobacco tar. IQOS cartridges are specially treated tobacco and are heated after insertion into a heating rod, the heating temperature is controlled at about 350 ℃, the tobacco material in the cartridge is heated to a temperature sufficient to evaporate nicotine and flavor smoke without burning, thereby avoiding the release of tar, releasing less chemicals, but having the same taste as real tobacco.
However, because tobacco is still used as a heating material in the IQOS cartridge, nicotine which is addictive to people still exists in the smoke, so that people cannot really quit smoking; moreover, the IQOS has less smoke, too few sucking mouths and unstable aerosol quantity, the mouth feel is obviously inferior to the mouth feels of the former mouths after the last mouth is sucked, the 'paste' taste is improved, the fragrance is reduced, the aerosol has no thickness and satisfaction, and the suction feeling is not good.
