Preparation of low-temperature fractions used in heated cigarettes and their use in heated cigarettes

Abstract

The invention belongs to the technical field of heated cigarettes, and in particular relates to a preparation method of a low-temperature fraction which can be applied to heated cigarettes and can increase the energy and its use in heated cigarettes. The preparation method includes the following steps: the raw materials include: 65 wt% of Dali burley tobacco leaves, 25 wt% of Hubei Jianshi burley tobacco leaves, and 10 wt% of Brazilian burley tobacco leaves; Ultrasonic extraction was performed for 55 min, and the first filtrate was collected. The residue part is extracted again by the same method, the second extract is collected, the filtrate is combined and concentrated to obtain the primary extract; Membrane filtration yields low temperature fractions. The low-temperature fraction of the present invention is added to the cigarette for smoking, which not only reduces the irritation of the smoke, but also increases the concentration of the smoke, and also greatly improves the power of the smoke.

Description

technical field [0001] The invention belongs to the technical field of heated cigarettes, and in particular relates to the preparation of a low-temperature distillate which can be applied to heated cigarettes and can increase the energy and its use in heated cigarettes. Background technique [0002] According to existing literature reports, more than 6,000 chemical constituents have been identified in traditional cigarette smoke. These chemical constituents are mainly generated by direct transfer of related constituents in tobacco or by pyrolysis and thermal synthesis reactions. Therefore, it can be seen that reducing the heating or combustion temperature can significantly reduce the release of harmful components in the flue gas. In addition, the sidestream smoke generated after traditional cigarettes is lit (mainly the smoke smoldering and escaping from the ignited end of the cigarette during the smoking interval) will cause passive smoking by non-smokers and cause resentme...

AI Technical Summary

Problems solved by technology

At present, tobacco extracts have been widely used in traditional cigarettes, but due to differences in raw materials, limitations in extraction techniques, analysis methods and use environments, most products are difficult to be directly transplanted into heated cigarettes to exert their efficacy

At present, the commonly used products obtained by ordinary solvent extraction method contain some substances that are not suitable for cigarette smoking, which will increase the discomfort of smoking, roughness and dryness

In addition, there are disadvantages such as large amount of solvent used, low efficiency, poor reproducibility, and easy loss of volatile components. The most important thing is that conventional extraction and separation methods will damage heat-sensitive aromatizing substances and cannot retain the aromatizing properties of tobacco itself.
