Abstract

The application relates to the technical field of tobacco accessory processing, in particular to a tobacco filter rod containing vinasse and a preparation method thereof. The vinasse filter tip rod is prepared from 50 parts of modified vinasse, 4-6 parts of humectant and 10-15 parts of acetate fiber. The modified vinasse is prepared by low-temperature vacuum drying, inert gas protection and molecular distillation dealcoholization to retain natural vinosity components, embedding a porous carrier, crosslinking and modifying with natural plant tannic acid, and spray granulating. The structure ensures that the vinasse functional layer is positioned in the middle of the flue gas channel, thereby avoiding high-temperature damage and realizing fragrance slow release and harmful substance gradient adsorption. Tannic acid can selectively intercept harmful substances such as nicotine, nitrosamine and the like, and the porous carrier and the fiber network cooperate to enhance physical adsorption of tar and carbon monoxide. The application utilizes the brewing waste with high value, has the functions of natural flavoring and harm reduction, has strong process compatibility and good sensory coordination, and has obvious environmental protection and industrialization values.

Description

Tobacco filter tip containing vinasse and preparation method thereof Technical Field The application relates to the technical field of tobacco accessory processing, in particular to a tobacco filter tip containing vinasse and a preparation method thereof. Background The distiller's grains are rich in crude protein, cellulose, organic acid and various natural volatile flavor substances, such as ethyl acetate, ethyl caproate, ethyl lactate, etc., and have strong and unique wine aroma characteristics. However, the current recycling mode of the vinasse is still rough, and the vinasse is mainly used as animal feed or agricultural organic fertilizer with low added value. Because the wine lees contain trace residual alcohol, have high moisture and are easy to spoil, and lack of high-efficiency separation and functional utilization technologies, natural fragrance components contained in the wine lees cannot be effectively extracted and utilized with high values, so that not only is the resource wasted, but also certain environmental pressure is brought. In the tobacco field, the functional design of filter materials is of great interest in order to improve the smoking experience of cigarettes and reduce health risks. In the prior art, activated carbon is added into a filter rod to adsorb harmful components such as tar, carbon monoxide and the like, or essence is implanted to explode beads, such as fruit flavor, peppermint flavor and bouquet type, so as to endow specific aroma to smoke. However, most of the fragrances used in the market are synthetic compounds, which have single fragrance and are not natural enough, and some consumers have doubts about the safety of chemical additives. Although the prior brands attempt to introduce the flavor of the white spirit into cigarettes, the implementation mode still depends on exogenously blended essence, and natural wine source substances are not really utilized, so that the flavor coordination is poor, the flavor retention time is short, and the sensory experience is limited. More importantly, the existing bouquet type filter tip generally lacks the selective regulation and control capability for alkaloids such as nicotine, and can not realize effective filtration of harmful components while releasing natural bouquet, so that the dual aims of natural aroma enhancement and harm reduction are difficult to achieve. Therefore, how to carry out high-valued and functional utilization on the vinasse generated in the white spirit brewing process, extract or in-situ retain the natural vinosity components of the vinosity, integrate the vinosity components into the cigarette filter rod material, develop a novel functional filter tip which can naturally release the vinosity and has good harmful substance adsorption performance, and become an important technical direction for connecting the resource utilization of the vinosity waste and the upgrading of tobacco products.
