example 1

[0024]Mix 20g of moso bamboo leaves, 40mg of graphene oxide, and 200mL of ethanol solution with a mass fraction of 60% and place them in a beater for 20 minutes to obtain bamboo leaf pulp. Put the bamboo leaf pulp in a reflux device and heat up to 70°C , heat-preserved and refluxed for 1.0h to obtain a crude extract, which was placed in a rotary evaporator and concentrated at 70°C for 10 minutes to obtain a flavonoid extract; Sugar solution and 2mL acetic acid solution with a mass fraction of 4% were flocculated for 20 hours to obtain a flocculated liquid, and the AB-8 macroporous resin was soaked in absolute ethanol for 20 hours, then packed into a chromatography column for compaction and the air bubbles were discharged. Place absorbent cotton with a thickness of 1mm on the surface of the resin layer, wash the resin layer with absolute ethanol at a flow rate of 10mL / min, put the floc liquid on the resin column, wash with distilled water until the eluent is colorless, and then ...

Abstract

The invention relates to the technical field of preparation of flavor for cigarettes, in particular to a preparation method of a natural flavor for the cigarettes. The preparation method comprises thefollowing steps: taking tobacco leaves as a raw material to obtain wood pulp of lignin, and introducing mixed gas of propylene and acetylchloride into the wood pulp to obtain aromatized wood pulp; taking cassava flour as a raw material, impregnating and mixing the impregnated raw material with egg white to obtain a reactive powder. According to the preparation method disclosed by the invention, trans-3-pentene-2-one is obtained by applying the principle that olefin and acidic halogen are in undergo Friedel-Crafts reaction to generate corresponding alpha, beta-unsaturated ketone, and further mouthfeel and flavor of the cigarettes are improved; flavonoid aromatic substances are leached from bamboo leaves by graphene oxide; besides, sugar in corn flour and protein in egg white undergo Maillard reaction under the heating condition; hundreds or thousands of intermediate molecules are produced in the reaction process; aromatic molecules are sucked into pores of micro-carbonized scented woodflour; moreover, coffee beans are added for improving the flavor of the natural flavor, so that smoke gas is gentle and delicate in aroma; the natural flavor has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of preparation of flavorings for tobacco, in particular to a preparation method of natural flavorings for tobacco. Background technique [0002] Tobacco flavors can be divided into chemical synthetic flavors and natural flavors. In recent years, as people pay more and more attention to the safety of cigarettes, the tobacco industry has also deepened research on cigarette harm reduction and tar reduction technology. Gradually reducing the tar content of cigarette products and developing new low-tar cigarettes is the overall development trend of the tobacco industry at home and abroad. . In the prior art, in order to achieve the purpose of reducing coke and harm, technologies such as filter tip, paper / acetate composite filter rod, natural air permeability tipping paper, and online laser drilling have been introduced. However, it has been proved by practice that while the tar in cigarettes is reduced, the ori...
