Method for preparing medium-temperature tobacco material used for non-combustion cigarette

Abstract

The invention discloses a method for preparing medium-temperature tobacco material used for a non-combustion cigarette. Mashing is directly carried out on tobacco raw material to prepare a substrate, aroma components are extracted from natural fragrant plant flowers through a supercritical CO2 fluid extraction-molecule distillation method, and then the substrate is coated with the aroma components to obtain the needed medium-temperature tobacco material. According to the method, the aroma components contained in the tobacco raw material self are kept to the maximum, and the selectivity of the supercritical CO2 fluid extraction-molecule distillation method is used for achieving directed extraction of chemical constituents of which the boiling point is from 300 DEG C to 400 DEG C in the natural fragrant plants, so that regulating and controlling of the chemical constituents of the medium-temperature tobacco material are achieved. The prepared medium-temperature tobacco material is rich in aroma, harmonious in smoke, good in sense organ comfort, obvious in sweet feeling and prominent in faint scent characteristic.

Description

technical field

[0001] The invention belongs to the technical field of combustion-free cigarettes, and in particular relates to a preparation method of a medium-temperature tobacco material used in combustion-free cigarettes. Background technique

[0002] The development of new non-combustible cigarettes is the focus and hotspot of tobacco industry research at the present stage. Although many achievements have been made in related research, the research on the directional release of aromatizing substances at a specific temperature is still blank. For traditional cigarettes, because they are burned at about 800°C, a large amount of tar and various aroma components are produced, and some components produced by combustion are harmful to the health of smokers. Therefore, it is of great practical significance for the development of cigarettes to develop tobacco materials that can release smoke similar to normal smoking cigarettes through dry distillation at a lower temperature. ...
