Description

Aroma-enhancing paper filter stick based on bioelectric fermentation and preparation method thereof Technical Field The application relates to the technical field of tobacco processing, in particular to a flavored paper filter stick based on bioelectricity fermentation and a preparation method thereof. Background The filter stick is used as a key component of the cigarette, and plays a vital role in improving the quality of the cigarette and meeting the requirements of consumers on unique flavor and taste. Traditional flavored paper filter sticks are mainly of 2 types: The first category is that the spice is adopted to prepare particles for direct addition, the aroma enhancement effect is weak, impurity gas is easy to introduce, the aroma duration is short, for example, patent application document with publication number of CN121242290A discloses an aroma enhancement paper filter stick for cigarettes, a binary aroma enhancement paper filter stick for cigarettes, a preparation method and application, the method for preparing the aroma enhancement paper filter stick for cigarettes comprises the steps of sequentially parching, fermenting and steam blasting fresh tea leaves, drying, crushing and screening the fresh tea leaves subjected to the steam blasting treatment to obtain solid spice, and mixing the solid spice with cellulose diacetate tows for cigarettes to prepare the aroma enhancement paper filter stick for cigarettes. The aroma-enhanced paper filter stick prepared by the method has rich aroma, but all miscellaneous gases are introduced. The second category is that the perfume is made into microcapsule particles and placed in the filter stick, and although a certain slow release effect is realized, the coordination of the fragrance and the tobacco fragrance is poor, and the mouth-by-mouth release uniformity is to be enhanced. The microcapsule releases perfume under the action of mechanical pressure or heat in the filter stick, but the high-temperature smoke generated by the combustion of the cigarette has large temperature difference with the filter stick, so that the perfume release time is not in cooperation with the main smoke flow component, which results in excessive heavy fragrance at the front section and light fragrance at the rear section of ‌, or a plurality of microcapsule perfumes (such as separated menthol and synthesized fruit fragrance) have low boiling point and strong volatility, while the microcapsule perfumes are easy to release, but ‌ covers natural sweet fragrance ‌ of the tobacco, the whole flavor balance ‌ is destroyed, or part of wall materials (such as gelatin-polysaccharide system) have insufficient stability in the acid-base or humidity environment of the cigarette filter stick, so that the ‌ is released quickly ‌ in the early stage and continuous coordinated release by mouth cannot be realized. ‌ ‌ ‌ A Meanwhile, tar reduction and harm reduction become a core proposition developed in the cigarette industry, the technology is used for iteratively pushing the tar content of a main stream product to be reduced to below 8mg from 10 mg-12 mg in the traditional process, and 3mg ultra-low tar control is realized for part of high-end products, but the problems of low fragrance, insufficient strength and the like are also accompanied in the tar reduction process, so that higher requirements are provided for fragrance preservation and release regulation of filter sticks. Therefore, in combination with the consumer's urgent need for upgrading the quality of cigarettes and the urgent direction of industry green production, there is a need to develop an innovative technology which can not only break the traditional flavor-enhancing defects, adapt to ultra-low-tar scenes, but also conform to the environmental protection concept. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a flavored paper filter stick based on bioelectric fermentation and a preparation method thereof, which can solve the problems of poor flavored effect, insufficient flavor coordination, high production energy consumption and poor environmental protection of the traditional filter stick. In order to achieve the above and related objects, the present invention adopts the following technical means: the invention provides a flavored paper filter stick based on bioelectrical fermentation, which comprises modified high-permeability forming paper and effective flavoring components which are fixed on the modified high-permeability forming paper through a loading and drying process and are derived from tobacco concentrate, wherein the surface of the modified high-permeability forming paper is coated with an adsorption enhancer prepared by mixing polyvinyl alcohol and nano silicon dioxide as raw materials, and the tobacco concentrate is prepared by bioelectrically fermenting waste tobacco as raw materials under a weak electric field. Further, the modified high-permeability formed paper has
