Method for analyzing characteristic aroma components of heat-not-burn cigarette

Abstract

The invention discloses a method for analyzing characteristic aroma components of a heat-not-burn cigarette. The method comprises the following steps of: mixing cut tobacco of the heat-not-burn cigarette with a microwave absorbing medium to obtain a pre-treated sample, and dividing the pre-treated sample into a first pre-treated sample, a second pre-treated sample and a third pre-treated sample; preparing a first to-be-detected sample by taking solid naphthalene as a first internal standard substance; preparing a second to-be-detected sample by taking phenethyl acetate as a second internal standard substance; taking a mixture of a dichloromethane solution of naphthalene and a dichloromethane solution of phenethyl acetate as a third internal standard substance to prepare a third to-be-detected sample; carrying out microwave pyrolysis on the to-be-detected sample to correspondingly obtain a gaseous to-be-detected object, and detecting the peak area of response by utilizing gas chromatography-mass spectrometry; respectively drawing a first standard curve and a second standard curve of the aroma components by using internal standard substances of dichloromethane solutions of naphthalene and phenethyl acetate; substituting the peak area result of the gaseous substance to be detected into the standard curve for mutual verification, and averaging to obtain the actual detection concentration of the characteristic aroma components.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to an analysis method for characteristic aroma components of heat-not-burn cigarettes. Background technique [0002] In recent years, the intensity of tobacco control has continued to increase globally. On the one hand, it aims to reduce environmental pollution, and on the other hand, it aims to reduce the potential threat to health caused by smoking. It also reduces the harmful components produced by high-temperature combustion of tobacco, greatly reducing the harm to smokers. The smoke generation of heat-not-burn cigarettes is significantly different from that of traditional cigarettes. There is a lack of research on tobacco smoke, and among the volatile substances produced during the heating process of heat-not-burn cigarettes, some characteristic aroma components have an important impact on the physiological experience of consumers when smoking, so the characteristic aroma compo...

Problems solved by technology

[0004] In the prior art, there are many studies on the analysis methods of smoke components of heat-not-burn cigarettes. For example, Chinese patent CN108776184 A discloses a method for detecting smoke components of heat-not-burn cigarettes. This patent uses a traditional cigarette smoking machine Suck heat-not-burn cigarettes, collect the total particulate matter on the filter, and use the isopropanol solution of n-butanol and 1,3-butanediol as the internal standard solution to extract, and obtain the extract of the total particulate phase. For gas chromatography measurement, since there is no universally verified and approved smoking machine for heat-not-burn cigarettes at present, this invention uses traditional cigarette smoking machines to smoke heat-not-burn cigarettes and collect total particulate matter, and then conduct extraction and detection. However, it is easy to produce the incomplete collection and incomplete extraction of the total particle phase, and the detection object is not a characteristic aroma component, and the internal standard used is not suitable; A method for the determination of 8 carbonyl compounds in cigarette mainstream smoke. Although this method can detect 8 carbonyl compounds at the same time, it is difficult to detect heat-not-burn cigarettes with low carbonyl compound content, and the recovery rate is low.
