Problems solved by technology

However, as a linear non-circulatory system, the ring-opening system has a small concentration factor for the volatile and semi-volatile components of the sample. The adsorption capacity of commonly used adsorbents is selective and the adsorption efficiency is not ideal, resulting in an incomplete range of measurable compounds.
Moreover, the waste gas evacuated during the extraction process directly enters the air, which is easy to pollute the experimental environment

Embodiment 1

[0058] The following preparation method is used to extract the volatile and semi-volatile aroma components in No. 1 cigarette shredded tobacco (cigarette brand: Zhonghua), and the steps are as follows:

[0059] 1) After removing the filter tip and cigarette paper from the cigarette, obtain a cut tobacco sample, weigh 14g cut tobacco sample and put it into a headspace glass sample bottle with a sealed septum, put the sample bottle into a temperature-controlled water bath heating pot to heat at 40°C Equilibrate for 15 minutes;

[0060] 2) After equilibrium, the sample bottle is continuously heated by a temperature-controlled water bath heating pot, and an electric diaphragm air pump is used to prepare air. The outlet flow rate of the electric diaphragm air pump is 800ml / min, and the cut tobacco sample in the sample bottle is purged for 24 hours;

[0061] 3) Use activated carbon trapping tubes to catch and purge the air gained, and the activated carbon trapping tubes are filled w...

Abstract

The invention provides a method for extracting tobacco volatile and semi-volatile aroma components. The method comprises the following steps: removing a filter tip and cigarette paper from a cigarette to obtain a tobacco shred sample, and filling into a sample bottle to carry out heating balance; after balancing, continuously heating the sample bottle, and blowing the tobacco shred sample in the sample bottle with air prepared by an air pump; using a capture pipe to capture air obtained by blowing, and connecting the capture pipe, the sample bottle and the air pump into a closed loop; after finishing capture, taking off the capture pipe, adding an organic solvent, and eluting into a collecting bottle in several times to obtain the tobacco volatile and semi-volatile aroma components. The invention further provides a device for extracting tobacco volatile and semi-volatile aroma components. According to the method for extracting tobacco volatile and semi-volatile aroma components, provided by the invention, the volatile and semi-volatile aroma components are extracted from prepared cigarette tobacco shreds through adopting closed-loop gas. The method for extracting the volatile and semi-volatile aroma components from tobaccos is simple, feasible and efficient.

Description

technical field [0001] The invention belongs to the field of separation and preparation of flavors and fragrances in tobacco, and in particular relates to a method for extracting volatile and semi-volatile flavor components of tobacco. Background technique [0002] As a sample pretreatment method in chromatographic analysis, purge and trap method can effectively and quickly separate and analyze tobacco volatile and semi-volatile components. At present, the purge and trap method mainly uses an open-loop system to purge the sample and trap it with an organic material adsorbent, and finally exhaust the exhaust gas. However, as a linear non-circulatory system, the ring-opening system has a small concentration factor for the volatile and semi-volatile components of the sample. The adsorption capacity of commonly used adsorbents is selective and the adsorption efficiency is not ideal, resulting in an incomplete range of measurable compounds. . Moreover, the waste gas evacuated d...
