Calculation method for furan substances in main-flow puff-by-puff smoke of fine cigarettes

Abstract

The invention provides a calculation method for furan substances in main-flow puff-by-puff smoke of fine cigarettes. The calculation method comprises the following steps: (1) preparing an internal standard solution, taking n-heptadecane as an internal standard substance and methanol as a solvent to prepare the internal standard solution; (2) preparing a standard working solution; (3) preparing a sample solution, smoking the fine cigarette according to a standard method and setting a puff quantity of smoking; collecting particle matters of each puff of the smoke by utilizing Cambridge filters;then adding the internal standard solution and an extracting solvent into each Cambridge filter with the captured particle matters respectively, and carrying out ultrasonic extraction; enabling an extracting solution to pass through an organic phase filtering membrane to obtain the sample solution; (4) analyzing by adopting a gas chromatograph-tandem mass spectrometer: detecting and analyzing thestandard working solution and the sample solution by adopting the gas chromatograph-tandem mass spectrometer; (5) drawing a standard working curve and calculating a sample result.

Description

technical field [0001] The invention relates to a method for calculating furan substances in mainstream puff-by-puff smoke of slim cigarettes, and belongs to the technical field of cigarette physical and chemical index detection. Background technique [0002] The aroma of tobacco is the core content of the quality and characteristics of tobacco and tobacco products, and consumers pay more attention to comfort while pursuing physiological satisfaction. Maximizing the aroma quality of tobacco products is an objective requirement of cigarette production. There are many components that constitute the aroma of tobacco leaves, there are about hundreds of them, and the components are complex, but the content is relatively low, and some of them are even very small. The composition, content and balance ratio of these components comprehensively affect the aroma and style characteristics of tobacco leaves and aroma. Among them, furan-like aroma substances occupy an important position ...
