Description
Technical Field
The invention relates to a method for slowly releasing mint and bean fragrance components in a heating non-combustible tobacco product and application thereof, belonging to the technical field of novel tobacco product fragrance slow release.
Background
In the field of novel tobacco products, the tobacco products which are not burnt after being heated are in a non-burning state through controlling the temperature of the internal tobacco materials so as to achieve the purpose of low harm, the taste of the tobacco products is closest to that of the traditional cigarettes, the appearance and the consumption mode of the tobacco products are similar to that of the traditional cigarettes, the sensory experience similar to that of the traditional cigarettes can be given to users to a certain extent, the harmfulness of smoking the traditional cigarettes can be greatly reduced, and therefore, the tobacco products which are not burnt after being heated become the hot spots with the most development potential in the industry.
Compared with the traditional cigarette, the heating mode and the smoking mode are changed, the whole tobacco part of the cigarette which is not heated and combusted is always in a heating state in the smoking process, the release of the flavor substances, particularly the release of the additional flavor substances with strong volatility is difficult to keep uniform, and the quality stability and the product taste and style are difficult to ensure. Therefore, the external flavor slow-release technology with strong volatility is one of the key basic technologies for endowing the heated non-burning tobacco products with better sensory quality and stable style characteristics.
The tobacco part of the cigarette which is not combusted by heating inevitably loses part of tobacco endogenous spices in the processing process, and because the heating temperature is low (200-350 ℃), fragrant substances are obviously insufficient during smoking, and the problem of miscellaneous gases such as wood and spicy flavor is caused, and the sensory quality of the tobacco part is improved by adding a certain amount of tobacco extract or exogenous spices. The mint spices such as menthol and menthone can play a role in reducing pungent and miscellaneous gases, improving aftertaste and relieving tongue surface residue in the smoking process; the lactone spices such as dihydrocoumarin and propyl caprolactone have proper burnt sweet bean fragrance, can enrich fragrance, coordinate and reduce miscellaneous gas, reduce irritation, and enhance aftertaste comfort. However, if the perfume monomers such as menthol and menthone are directly used for perfuming the tobacco part of the non-combustible cigarette, the perfume monomers are extremely volatile and lost in the drying process and the subsequent storage stage, and the problem of non-lasting fragrance exists; and the cigarette is easy to be released out at the first mouth and the second mouth in the heating process of heating the non-burning cigarette, so that the difference before and after smoking the taste is large, and uncomfortable sensory experience is caused.
