Silk protein compound filter tip and preparing method thereof

Abstract

The invention discloses a silk protein compound filter tip and a preparing method thereof. Silk protein powder or granules are added in conventional cigarette filter tips. The silk protein powder is prepared from crushed plateau silks and is about 1-8 mm in length; and the silk protein granules are prepared by blending plateau silk protein powder less than 2 mm with honey or propylene glycol and water and through the procedures of granulating, drying and sieving. The silk protein powder or granules are evenly added on the filter tip to obtain the silk protein compound filter tip, wherein the adding amount of the silk protein powder accounts for 5%-20% of the total weight of the filter tip. By the invention, tar in the mainstream smoke of cigarettes is reduced by 5.6%-15.6%; hydrogen cyanide (HCN) is reduced by 10.2%-21.86%; NNK (Nitrosamine Ketone) is reduced by 30.0%-51.2%; crotonic aldehyde is reduced by 17.7%-33.8%; and BaP (Benzo A Pyrene) is reduced by 6.9%-21.7%. Other harmful constituents in smoke are also reduced to different extents; the smoke is endowed with an obvious cool sweet taste; the simulation of the smoke can be obviously reduced; and the cigarette fragrance is enriched and refined.

Description

technical field [0001] The invention relates to a filter tip rod for cigarettes, more specifically, the invention relates to a silk protein composite tip rod which can reduce the harmful components of cigarette smoke. At the same time, the invention also relates to a preparation method of the composite nozzle stick. Background technique [0002] At present, efforts to improve the smoking safety of cigarettes have become the consensus of the tobacco industry at home and abroad. In order to reduce the tar content in the mainstream smoke of cigarettes and the trace harmful chemical components in it, and improve the safety of cigarettes, tobacco researchers have conducted a lot of scientific research. Research, extensive application of new technologies, new processes, new materials, and new equipment, has done a series of work in the development and production of low-tar cigarettes and low-hazard cigarettes. In order to keep the aroma and style characteristics of cigarette smok...

Problems solved by technology

Although CN101032346 discloses the report of making cigarette tip rods completely with silk, because silk is relatively soft, it is not suitable for directly being used as tow to make cigarette tip rods, so this method is difficult to realize industrialized production of silk cigarette tip rods, and the produced The cost of the cigarette holder is relatively high
