Technical Field
The invention relates to the field of tobacco processing, in particular to a treatment method for improving side-stream smoke of aromatic tobacco.
Background
The aromatic tobacco is a special tobacco type of safflower tobacco, mainly comprises three types of IZMIR, SAMSUN and BASMA according to the variety, is also called Turkey tobacco and oriental tobacco, has the quality characteristics of strong fragrance and pure taste, has special application value in tobacco products, and is one of important raw materials for producing mixed type, outer fragrance type and oriental type cigarettes and pipe tobacco. The aroma of the aromatic tobacco is mainly from glandular hair secretion or exudate, and the aroma is closely related to soil, climate and cultivation measures.
The traditional aromatic cigarette has the characteristics of strong taste, wide material consumption, capability of effectively reducing tar content so as to reduce the harm of smoking to human health, is deeply favored by smokers and is always liked by salt and pepper powder in cigarettes. Because the aromatic cigarette has natural aroma, the aromatic cigarette is soft and smooth when entering the throat, the aroma is full, and the sidestream smoke of the aromatic cigarette is more prominent during combustion, so the aromatic cigarette is popular in European and American markets. In contrast, in the Chinese market, due to differences in culture, diet and living habits, the relatively prominent sidestream smoke of the aromatic cigarette is not accepted by Chinese consumers, the consumer generally reflects that the mixed type cigarette has choking acid odor, and the feeling of the acid odor is mainly brought by micromolecular acids and isoprene acids generated when the aromatic cigarette in the cigarette burns. Therefore, the sidestream smoke of the aromatic cigarette is improved, the sidestream smoke has great significance for improving the smoking environment feeling of consumers and improving the social scene of cigarettes, and the sidestream smoke has a positive effect for further expanding the consumer groups of Chinese style mixed cigarettes.
In view of this, the invention is particularly proposed.
