Abstract

The invention provides a method for simultaneously measuring the content of moisture, 1,2-propanediol and glycerol in tobacco. The method comprises the steps of: A) extracting a tobacco sample using an extracting agent containing internal standard to obtain an extract liquor; and B) performing quantitative analysis on moisture, 1,2-propanediol and glycerol in the extract liquor using a Gas Chromatography Dual-column and Dual-detector. Through extracting with solvent and then performing quantitative analysis and detection using Gas Chromatography Dual-column and Dual-detector Method, the methodcan measure the content of moisture, 1,2-propanediol and glycerol in tobacco sample quickly and accurately. The method provides technical support for the development of heat-not-burn tobacco products.

Description

technical field

[0001] The invention belongs to the technical field of detection and analysis applications, in particular to a method for simultaneously measuring the contents of moisture, 1,2-propanediol and glycerol in tobacco. Background technique

[0002] Heat-not-burn cigarettes mainly release aroma components through heating rather than burning. The reduction of heating temperature greatly reduces the components of mainstream smoke, sidestream smoke and environmental smoke. The moisture content in the tobacco material of heat-not-burn cigarettes will directly affect the sensory experience of heat-not-burn cigarette products. Similar to e-cigarettes, 1,2-propanediol and glycerin are often added as atomizers to the tobacco material of heat-not-burn cigarettes. Different types and contents of atomizing agents have a direct impact on the smoke generation effect and sensory quality. Therefore, accurate and rapid determination of moisture, 1,2-propanediol and glycerol cont...
