The invention belongs to the technical field of cigarette production, and particularly relates to a cigarette tar-reducing harm-reducing process, which includes placing tobacco shred or tobacco leaf in a rotating device for supercritical fluid extraction, and treating the extracted tobacco shred or tobacco leaves by microwave or hot air at 80 DEG C-150 DEG C after extraction. By the cigarette tar-reducing harm-reducing process, main aromatic ingredients of the tobacco leaf are maintained, and nicotine or other harmful ingredient precursors in the tobacco leaf are selected lowered. By the cigarette tar-reducing harm-reducing process, cigarette quality can be improved, release amount of tar and harmful ingredients in cigarette smoke can be reduced, and cigarette safety can be improved.

The invention discloses a tobacco flavor with uniform and stable and a preparation method thereof. The tobacco flavor is an extract with a relative density of 1.02 to 1.20 which is extracted by 60-95 mass percent ethanol from a mixture, wherein the mixture comprises red date, Chinese angelica and dwarf lilyturf tuber in a weight ratio of 0.2-30.0:0.5-20.0:0.5-30.0. The tobacco flavor can degrade cigarette tar. When combined with natural tobacco plant fragrance, the tobacco flavor makes cigarettes fresh, elegant, sweet, pure, mild, light, transparent and thus greatly enhances the quality of cigarettes. The invention also discloses a method for preparing the tobacco flavor. The method can make a uniform, stable and sweet liquid flavor additive without impurities, and the content of the fragrance source component of the tobacco flavor is over 80%.

The invention discloses a preparation method of a porous material made of Chinese herbal medicine extracted residues. Meanwhile, the invention discloses application of the porous material made of the Chinese herbal medicine extracted residues for adding the porous material into cigarette filters so as to reduce tar and lessen harm for cigarette smoke and/or increase moist feeling of the smoke.

The invention relates to a reconstituted tobacco containing a directionally compound-extracted tobacco endogenous incense matter, and a cigarette prepared therefrom. The reconstituted tobacco is prepared by adding the tobacco endogenous incense matter into a reconstituted tobacco substrate, and the ratio of the adding amount of the tobacco endogenous incense matter to the weight of the reconstituted tobacco substrate is 1:0.5 to 1.5; the tobacco endogenous incense matter comprises a polarity aroma matter directionally extracted from tobacco by a water extraction method, a non-polarity aroma matter directionally extracted from the tobacco by a supercritical CO2 extraction method, and moderate and weak-polarity aroma matters directionally extracted from the tobacco by an ethanol extraction method, the mass ratio thereof is 1000:0.1 to 5:1 to 50. The quality of the reconstituted tobacco is enhanced, the amount of aroma is increased, the note is enhanced, the natural smoke flavor is set off, the dryness of smoke is reduced, the fluid sense is enhanced, and the cigarette comfort is improved.

The invention discloses an aroma-increasing and humidity-preserving additive for cigarettes and a preparation method and application thereof. The additive contains a traditional Chinese medicine extract composition or a compound traditional Chinese medicine extract. The traditional Chinese medicine comprises epimedium, eclipta herb, coltsfoot flower, leonurus, dandelion and trichosanthes peels. The preparation method of the aroma-increasing and humidity-preserving additive comprises respectively using a solvent to extract and refine the epimedium, the eclipta herb, the coltsfoot flower, the leonurus, the dandelion and the trichosanthes peels and mixing the ingredients according to the proportion of 1-8:0.8-6:0.5-4:0.3-4:0.3-5:1 to prepare the aroma-increasing and humidity-preserving additive, or mixing the epimedium, the eclipta herb, the coltsfoot flower, the leonurus, the dandelion and the trichosanthes peels according to the proportion of 0.5-8:0.5-6:0.2-4:0.3-4:0.3-5:1 and then using the solvent to perform extraction and refining to prepare the aroma-increasing and humidity-preserving additive. The additive is added into tobacco shreds, cut stems and slices for cigarettes, and the adding proportion is 0.002-1%wt. After the additive is added into the tobacco shreds, the cut stems and the slices for the cigarettes, the moisture of the tobacco shreds can be maintained in the normal-temperature dry environment, the additive has good physical humidity-preserving effect and integrally improves the intrinsic quality of the cigarettes.

The invention discloses a preparation method of a porous material made of residues obtained after extraction of aromatic plants and meanwhile further discloses application of the porous material made of the residues obtained after extraction of the aromatic plants that the material is mixed into cigarette filter tips so that tar and other harmful components in cigarettes can be reduced and/or moistening feeling of smoke can be enhanced.

The invention discloses a fresh and sweet type humectant for cigarettes. The fresh and sweet type humectant is prepared from a solvent, natural plant extract and a humidity-keeping accelerant, whereinthe solvent is one or a mixture of propylene glycol and ethanol; the natural plant extract is mixed extract of apples, green plums and shaddock peels; the humidity-keeping accelerant is a moss extracting solution. According to the fresh and sweet type humectant disclosed by the invention, the humectant is prepared by reasonably compounding the apples, the green plums and the shaddock peels for the first time; the prepared humectant has a fresh and sweet spice aroma and abundant layers; the aroma of the cigarettes can be increased, the dry sensation of smoke is reduced and the comfort of the cigarettes is improved; meanwhile, the fresh and sweet type humectant has good humidity-keeping performance and has a good market prospect and application value.

The invention discloses a preparing method of a residue porous material obtained after tobacco extraction and further discloses application of the residue porous material obtained after tobacco extraction in being mixed into cigarette filters to depress tar and reduce harmful substances of cigarette smoke and/or increase wetness of smoke.
