Description

Technical Field

[0001] The invention relates to the technical field of flavor and fragrance development, and in particular to a method for preparing a filter rod for cigarettes based on natural citron flavoring. Background Art

[0002] Cigarette filter rods are an indispensable and important part of cigarettes. As a bridge between smokers and mainstream smoke, they can effectively filter out some harmful components in smoke, and therefore have received widespread attention and application. At the same time, filter rods are also an important carrier for non-burning flavoring of cigarettes. Non-burning flavoring directly adds flavoring substances to tobacco auxiliary materials, which do not participate in combustion and have little damage to effective ingredients, and avoid the introduction of impurity components with negative effects. The added functional substances act directly on the smoke, and the components are known and controllable, which is more direct and targeted in solidifying the style characteristics of cigarettes and strengthening product features.

[0003] Natural aroma raw materials are considered the cornerstone of cigarette flavor enhancement and quality improvement due to their own richness and effectiveness, and have gradually become the key to the characteristic flavor and aroma of Chinese cigarettes. Combining specific and effective natural plant materials with cigarette filter rods, and introducing flavor substances when smoking cigarettes through the slow-release characteristics of natural plant particles themselves, to achieve natural plant material cigarette flavor enhancement that does not participate in combustion is an important way to improve the quality of cigarette products.

[0004] Tangerine peel aroma is one of the important basic plant aromas. Its unique fruit aroma and fermented ingredients have attracted extensive attention from scholars from all over the world. However, due to the high water content of citrus peel and the serious loss of aroma substances during the drying and dehydration process, the application of tangerine peel materials in cigarette filter rods is greatly limited. Using appropriate technical means to maintain the tangerine peel aroma to the greatest extent and prepare it into flavored cigarette filter rods has become an industry technical demand that needs to be urgently addressed.
