Embodiment Construction

[0027] Attached below Figure 1-6 Embodiments of the present invention are described.

[0028] A method for the determination of volatile and semi-volatile organic acids in mainstream cigarette smoke, which uses gas chromatography-mass spectrometry for determination, internal standard method for quantification, sample pretreatment without derivatization, direct solvent extraction, and GCMS detection and analysis. The content of 25 kinds of volatile and semi-volatile organic acids in the total particulate matter of cigarette mainstream smoke was determined. Among them, the 25 kinds of volatile and semi-volatile organic acids in the total particulate matter of cigarette mainstream smoke measured are: acetic acid, formic acid, propionic acid, isobutyric acid, butyric acid, 3-methyl butyric acid, valeric acid, 3-Methylpentanoic acid, caproic acid, heptanoic acid, caprylic acid, pelargonic acid, capric acid, undecanoic acid, benzoic acid, lauric acid, tridecanoic acid, myristic ac...

Abstract

The invention provides a method for determining volatile and semi-volatile organic acids in cigarette mainstream smoke, and belongs to the technical field of cigarette chemical analysis and detection. According to the method, the content of 25 kinds of volatile and semi-volatile organic acids in mainstream cigarette smoke can be determined simultaneously by GC-MS, internal standard quantitative method, sample pretreatment without derivatization, direct extraction with dichloromethane, GCMS analysis and specific pretreatment process for samples. The precision of the method for detecting the volatile and semi-volatile organic acids in the cigarette mainstream smoke is improved, and the method has the advantages of being rapid, high in operability and convenient to process in batches.

Description

technical field [0001] The invention belongs to the technical field of cigarette chemical analysis and detection, and in particular relates to a method for measuring volatile and semivolatile organic acids in cigarette mainstream smoke. Background technique [0002] The aroma components in tobacco are important indicators for evaluating the quality of tobacco and cigarettes. The analysis and research of aroma substances in tobacco and smoke is of great significance for improving the quality of tobacco and its products. The type and content of organic acids in tobacco and smoke directly affect the smoking quality of cigarettes. The acidic components can not only neutralize the smoke and reduce irritation, but also significantly enhance the taste. The content of volatile organic acids in tobacco is very low, some even only 0.01%-0.05%, but its impact on the sensory quality of tobacco leaves is far greater than that of polyacids and higher fatty acids. At the same time, volatil...
