Abstract

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.

Description

technical field [0001] The invention relates to a residue porous material after extraction of aromatic plants and its application, and belongs to the technical field of additive materials for cigarette mouthpieces. Background technique [0002] The flavor and fragrance processing industry often involves solvent extraction of aromatic plants, such as water extraction or alcohol extraction. These extraction operations produce a large amount of residues after extraction of aromatic plants, and effective methods are needed to deal with these wastes. [0003] The tobacco industry is also looking for materials that can effectively absorb tar and other harmful substances in cigarette smoke to achieve tar reduction and harm reduction. At present, the conventional filter material in the tobacco industry is cellulose acetate tow. Although it can effectively absorb tar and other substances, it also has shortcomings. The cigarette smoke filtered by it is slightly "dry", which affects th...
