Embodiment 1

[0020] A refined preparation method for natural flavors suitable for heat-not-burn cigarettes. The natural flavors are weighed, diluted with an organic solvent 25 to 30 times the mass, and the diluted solution is subjected to a temperature rise reaction at a temperature range of 200 to 300°C for full reaction Dissolved and filtered; then the filtrate was cooled and quick-frozen at a temperature range of 1 to -10°C, and filtered to remove impurities; then the filtrate was subjected to molecular distillation at a distillation temperature of 100 to 150°C and a distillation pressure of 10 2 Pa, collect light components to obtain refined natural flavor products specially used for heat-not-burn cigarettes.

[0021] The organic solvent can be one or a mixture of glycerol, propylene glycol, polyethylene glycol, isoprene glycol, glyceryl triacetate, and glyceryl caprylate, and glycerol is used in this embodiment.

[0022] The natural spices can be one or more of various types of spice ...

Embodiment 2

[0024] A refined preparation method for natural flavors suitable for heat-not-burn cigarettes, comprising weighing fennel oil, wild carrot oil, clove oil, coriander seed oil, celery seed oil, nutmeg oil, dill oil, Baba extract, maple extract, chicory extract, chamomile extract, orris root oil, violet leaf extract, hops, peppermint oil are combined, add 1 times the mass of propylene glycol for dilution, and introduce the diluted solution into high temperature reaction The kettle is heated up to 50°C, fully reacted and dissolved, and then filtered; then the filtrate is introduced into a low-temperature freezing tank for cooling and quick freezing, and the temperature is gradually lowered to 4°C, and the impurities are filtered out; finally, the filtrate is molecularly distilled at 60°C ℃, the distillation pressure is 10 -1 Pa, collect light components to obtain natural flavor products specially used for heat-not-burn cigarettes.

Embodiment 3

[0026] A refined preparation method for natural flavors suitable for heat-not-burn cigarettes. The extracts of oak moss and tree moss are diluted with three times the mass of polyethylene glycol, and the diluted solution is introduced into a high-temperature reactor for heating reaction, and the temperature is gradually raised After fully reacting and dissolving at 150°C, filter it; then import the filtrate into a low-temperature freezing tank for cooling and quick freezing, and gradually lower the temperature to -8°C, and filter to remove impurities; finally, carry out molecular distillation of the filtrate at a distillation temperature of 100°C and a distillation pressure of 10 -2 Pa, collect light components to obtain natural flavor products specially used for heat-not-burn cigarettes.

Abstract

The refined preparation method of natural flavor suitable for heat-not-burn cigarettes is to dilute the natural flavor by adding 1 to 50 times the mass of an organic solvent, raise the temperature of the diluted solution to 50-350°C, and filter after fully reacting and dissolving; then the filtrate Perform cooling and quick-freezing at a temperature range of 4°C to -20°C, filter to remove impurities; then carry out molecular distillation of the filtrate at a distillation temperature of 60-250°C and a distillation pressure of 10 ‑1 ~10 5 Pa, collect light components to obtain refined natural flavor products for heat-not-burn cigarettes. The invention can significantly improve the aroma quality of the heat-not-burn cigarette, and avoid burnt smell during heating.

Description

technical field [0001] The invention relates to the technical field of flavors and fragrances for tobacco, in particular to a method for preparing natural flavors for heat-not-burn cigarettes. Background technique [0002] Heat-not-burn cigarettes use a special heating device (smoking set) to heat the treated shredded tobacco (special cartridge) to a certain temperature, but do not ignite the tobacco, so that the shredded tobacco is heated enough to emit smoke, and the taste is closer to real smoke. The main feature is that the heating temperature is lower than 350°C, which is a "low temperature cigarette". Under normal circumstances, ordinary cigarettes will produce many harmful substances at a high temperature of 350°C to 600°C when smoking, while low-temperature cigarettes are all below 350°C, and harmful substances will be reduced. Heat-not-burn cigarettes with tobacco flakes as fillers are prepared into thin flakes by using composite technology, and formed by multi-ele...
