Tobacco curing-flavor filter capable of reducing heavy metal content in flue gas and preparation method thereof

Abstract

The invention relates to a tobacco-cured flavor filter tip capable of reducing the content of heavy metals in smoke and a preparation method thereof, which belongs to the technical field of tobacco auxiliary materials. The method is to add polyhydric alcohol and organic acid-metal salt compound to tobacco powder, after mixing, heat in a container connected with a condensing reflux device for reaction; add the obtained product into an organic solvent, and first ultrasonically extract, Then shake and extract, then centrifuge, take the upper liquid and filter it with an organic filter, distill the filtrate under reduced pressure, prepare the obtained concentrate into a solution with a mass concentration of 1% to 5%, and add polyferric sulfate to the solution to mix Homogenize and then alcoholize, and finally add the alcoholized liquid evenly to the filter tow, and make the filter according to the conventional method, that is, obtain the tobacco roasted flavor filter. The preparation method of the invention is simple, the cost is low, and the prepared filter tip can significantly reduce the heavy metal content of cigarette smoke, and can reduce the amount of miscellaneous gas and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of tobacco auxiliary materials, and in particular relates to a tobacco roasting flavor filter tip capable of reducing the content of heavy metals in smoke and a preparation method thereof. Background technique [0002] As cigarette consumers pay more and more attention to their own health and have higher and higher requirements on the intrinsic quality of cigarettes, low-tar and high-quality cigarettes have become the focus of current research. However, low tar must be accompanied by loss of cigarette aroma and poor comfort. In terms of quality, the current domestic cigarette products have certain deficiencies in smoking quality and sensory comfort, such as weak aroma, strong dryness, insufficient sweetness, and poor comfort. [0003] At present, directly adding some flavoring substances with flavoring and sweetening effects into the filter rod has become a very potential compensation application method. T...
