Description

FIELD OF THE INVENTION

The present invention relates to the technical field of tobacco aerosol generation, in particular to an aerosol-generating product for modulating the release of flavored substances and a method thereof.

BACKGROUND OF THE INVENTION

As the most direct object for consumers to consume cigarette commodities, the quality of the cigarette smoke is an important factor in determining the quality of the cigarette commodities. The flavor of the traditional cigarette mainly relies on a reasonable leaf group formula, but the flavor of the cigarette can be enriched and corrected by adding aroma, and the flavor of the cigarette is kept stable. For new tobacco products, in particular for heated cigarettes and electronic cigarettes, the flavoring effect is more prominent: on the one hand, the flavored substances can supplement and improve the natural flavor of the tobacco substrate or the smoking medium; on the other hand, the flavored substance has a masking effect on the impurities generated during the aerosol generation process, and improves the taste of the aerosol product; in addition, the flavored substances may help aerosol products to create a novel and unique style of flavor. Compared with the flavoring process, the release of the flavored substance during the use of the aerosol-generating product is more critical, and the stability of the release determines the stability of the aerosol taste and has an important impact on the quality of the aerosol product.
