Phase change filter rod additive and its preparation method and application

Abstract

The invention provides a phase change filter rod additive and its preparation method and an application, and belongs to the technical field of a filter insert in a filter nozzle. The phase change filter rod additive can ensure the uniformity of fragrance release, eliminate difference of cigarette taste, improve stability, and enlarge the using scale of the fragrant matter on the basis of ensuringthe fragrance retention ability of the filter rod. The additive comprises fragrant ingredients, embedding materials coated with the fragrant ingredients and a phase change matter. The preparation method includes steps of preparation of fragrant ingredients, embedding of fragrant ingredients, mixing and emulsification, and others. The phase change filter rod additive can keep solid phase under roomtemperature and improve the fragrance retention ability; in smoking, the additive is changed to be liquid phase under the smoke temperature; by matching with the effect of beta-cyclodextrin molecule,the continuity of essence release is improved, the continuity and uniformity of the cigarette fragrance is guaranteed; the filter road additive also can avoid collapse and softening of the filter rodand accordingly enlarge the scale of the essence for the filter rod.

Description

technical field [0001] The invention relates to the technical field of cigarette filter manufacturing, in particular to a phase-change additive for a cigarette filter rod. Background technique [0002] At present, there are various flavoring technologies for cigarettes, mainly including the following: [0003] ① Directly make flavor substances into granules or add them to filter sticks or shredded tobacco by coating or spraying; [0004] ②Combine aroma substances with adsorbent materials such as activated carbon and add them to the filter rod; [0005] ③ Molding the incense thread or the incense slice soaked in the fragrance substance together with the tow; [0006] However, there is a common deficiency in the above three flavoring methods. Since the temperature of cigarette smoke enters the filter rod, its temperature drops below 100°C. Therefore, the selected fragrance substances in the filter stick fragrance enhancement technology are usually volatile materials, which ...

AI Technical Summary

Problems solved by technology

[0009] First of all, the fragrance substance is mixed in the gel material, which can indeed prevent the fragrance from diffusing and volatilizing during storage, and improve the fragrance retention ability of the filter rod added with this material, but the specific surface area of ​​the gel increases after being added to the filter rod, and some volatile Strong flavor substances will still form a volatilization channel through the contact of the gel surface with the air and gradually volatilize and lose, resulting in changes in the smoking taste of cigarettes during the sales cycle, affecting the consistency of product quality; at the same time, when smoking, after the smoke circulates, When the gel is preheated beyond its phase transition point, it will melt, and the flavoring substances mixed in it will volatilize rapidly when exposed to smoke, and the volatilization time is relatively short, and it is concentrated in the early stage of smoking, which leads to the actual smoking of cigarettes. The experience is that in the first stage, due to the concentrated volatilization of the aroma substances, the aroma is relatively strong, while in the later stage, the aroma substances are completely volatilized, the aroma is lighter, the aroma is released unevenly in the front and rear stages, and the difference in taste is large, which affects the overall taste of the cigarette
