Embodiment 1

[0031] The assay method of floral aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0032] 1) Suck the balanced and screened brand 1 cigarettes according to the standard smoking conditions specified in YC / T29-1496, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 10 cigarettes, and then filter the Cambridge filter Place the tablet in a 50mL Erlenmeyer flask with a stopper and lay it flat on the bottom of the bottle, add 20mL of internal standard (styroyl propionate) acetone solution with a concentration of 0.1 μg / mL, shake at room temperature for 30min, take 2mL of supernatant, and obtain Test sample solution;

[0033] 2) GC-MS is used to detect the sample solution to be tested obtained in step 1);

[0034] The chromatographic conditions are: chromatographic column: DB-5ms (60m×0.25mm×0.25μm); carrier gas: He; column flow rate: 1mL / min; inlet temperature: 250°C; temperature prog...

Abstract

The invention belongs to the technical field of smoke component detection, and particularly relates to a method for determining floral components in mainstream smoke of cigarettes. The method comprises the following steps: extracting collected cigarette mainstream smoke particulate matters by using acetone to obtain an extracting solution; analyzing the extracting solution by adopting gas chromatography-mass spectrometry, and detecting the content of the floral components by adopting an internal standard method, wherein an internal standard substance used in the internal standard method is storax propionate, and the floral component is composed of heptanol, sec-octyl alcohol, p-toluenemethyl ether, 2-ethylhexanol, ocimene, phenylacetaldehyde and other components with floral fragrance. Themethod disclosed by the invention can be used for simultaneously detecting the contents of the 45 floral components in the cigarette smoke, and has the advantages of rapid detection, high sensitivity,good selectivity and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of detection of smoke components, and in particular relates to a method for measuring floral fragrance components in mainstream smoke of cigarettes. Background technique [0002] According to the industry standard "YCT 497-2014 Method for Sensory Evaluation of Chinese Style Cigarette Style", floral aroma is an integral part of cigarette aroma style and is one of the important flavor notes of cigarettes. The floral aroma components in cigarette smoke may be the inherent components of tobacco leaves, or may be derived from the burning or artificial addition of tobacco leaves. There may be differences in the composition of floral aroma components in the smoke of different cigarettes, which is an important material basis for the different floral aroma performances of various cigarette products. Investigating the composition of key components with floral aroma characteristics in various types of cigarette smoke ...
