Embodiment Construction

[0023] The present invention is further described by the following specific examples, but does not limit the present invention.

[0024] Content determination example:

[0025] (1) The cigarette samples used were sorted by weight and draw resistance, and the uniform test cigarettes were picked out as unflavored blank cigarette samples.

[0026] (2) The prepared mixed spice solution (preparation method: accurately weigh a certain amount of spice monomer standard 3-methylpentanoic acid, hexanoic acid, heptanoic acid, caprylic acid, nonanoic acid, capric acid, etc.) acid, dodecanoic acid, myristic acid, using absolute ethanol as solvent to prepare a mixed flavor solution with the concentration of each flavor monomer being 12-20mg / mL), inject it into the unflavored blank cigarette sample, and the injection volume of each blank cigarette After the injection, place the flavored cigarette in a sealed box with constant temperature and humidity (22±2°C, RH 60±5%) for 1 week.

Abstract

The invention relates to a method for measuring the transfer behavior indexes of fatty acids perfume monomers in cigarettes, which is characterized in that by utilizing a simultaneous distillation extraction device and a gas phase chromatography the method makes a gas phase chromatograph analysis on the distribution of the fatty acids perfume monomers injected into the cigarettes in tobacco rods and the transfer behavior of cigarettes after being smoked towards a mainstream flue gas particle phase and a filter tip, that is, an analyzing method is used for analyzing and determining the amount of fatty acids in the cut tobacco, the filer tip and the cigarette paper of a flavoring cigarette and a blank cigarette before being smoked and the amount of fatty acids in the mainstream flue gas particle phase and the filer tip of a flavoring cigarette after being smoked so as to obtain detection values; then a calculation formula of a research index is used for calculating, and furthermore, the transfer index of the fatty acids perfume monomers above C6 which are injected into the cigarettes in the cigarettes is determined. The method has the advantages of simplification and convenience, good reproducibility and high analysis and determination sensitivity, which can determine the fatty acids above C6 and provides a new analysis and research method for the quantization investigation on tobacco flavoring.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for measuring the transfer behavior index of fatty acid flavor monomers in cigarettes. The method can realize the determination of the transfer behavior of fatty acid flavor monomers in cigarettes through chemical detection results. Quantitative investigation of flavoring provides a new means of analytical testing. Background technique [0002] The acidic components in tobacco can not only adjust the pH of cigarette smoke, reduce the irritation of smoke, but also significantly enhance the concentration of smoke, making the taste mellow, especially some volatile and semi-volatile acidic components have a relationship with the quality of tobacco. More closely related ones, such as 3-methylvaleric acid, play an extremely important role in the distinctive aroma of oriental tobacco. In view of the direct impact of acidic components in tobacco on tobacco quality, cigarette manufacturer...
