Problems solved by technology

Some markers exist in a small amount in shredded tobacco, which will interfere with the uniformity evaluation; although other markers do not exist in shredded tobacco, only one marker is not enough to complete and systematically evaluate the uniformity of cigarette flavoring process

Embodiment 1

[0089] According to the selection principles of external markers: a) External markers do not exist in cigarette essence or shredded tobacco, nor will they be introduced during the production process. b) The physical and chemical properties of the added markers are stable, easy to be extracted and analyzed qualitatively and quantitatively. c) The structure and properties of the external markers are similar to the various characteristic aroma components in the cigarette flavor, and do not affect the aroma style of the cigarette.

[0090] Since there are many types of ester compounds in tobacco flavors and they play a key role in the quality of aroma, while the boiling point distribution of phenylglycolic acid esters is uniform, and their chemical structures and properties are similar to those of various ester compounds in flavors. Added and not present in the tobacco background, it is suitable as an external marker for evaluating the uniformity of flavoring.

Embodiment 2

[0101] During the determination, accurately weigh 0.5000g (accurate to 0.0001g) of each of the 5 mandelic acid ester standards and place them in a 50mL volumetric flask, dissolve them with ethanol and constant volume to obtain a primary mixture with a mass concentration of 10000μg / mL Standard stock solution, and then take 0.5mL primary stock solution and dilute it to a 50mL volumetric flask to obtain a secondary mixed standard stock solution with a mass concentration of 100μg / mL, and store it in a 4°C refrigerator. Accurately pipette 0.05, 0.25, 0.50, 2.50, 5.00mL of the secondary mixed standard stock solution into a 50mL volumetric flask, add 0.5mL of benzyl acetate internal standard solution (100μg / mL), and dilute with ethanol to obtain the respective concentration A series of standard working solutions of 0.10, 0.50, 1.00, 5.00, 10.00 μg / mL.

[0102] A series of standard working solutions with different concentrations were analyzed by GC-MS / MS to obtain the linearity of the...

Embodiment 3

[0106] According to the method of flavoring and sampling in Example 1, select the same batch of flavored cut tobacco samples, weigh 5 parts in parallel, and quantitatively add mandelic acid ester standard solutions at three concentration levels of low, medium and high respectively to measure the concentration before and after adding the standard. The recovery rate of each mandelic acid ester was calculated by the average value of the determined content. The recoveries of the five mandelic acid esters at each addition level were all between 90.98% and 107.17%, which indicated that the recoveries of this method were better. The relative standard deviations (RSDs) of the 5 mandelic acid esters are all below 10%, indicating that the method has good reproducibility. The results are shown in Table 2.

Abstract

The invention provides a cigarette flavoring uniformity detection method based on an additional marker. The method comprises the following steps: adding a phenylethanolate compound serving as an additional marker into a tobacco essence, wherein the tobacco essence containing the additional marker is added to tobacco shreds through a flavoring process, balancing, grinding and sieving different batches of flavored cut tobaccos, performing accelerated solvent extraction to respectively obtain extract liquor of different batches of cut tobaccos, performing gas chromatography-tandem mass spectrometry analysis on the extract liquor to obtain the content of additional markers in a plurality of extract liquor, and further conducting calculation to obtain the flavoring uniformity of cigarettes. According to the cigarette flavoring uniformity method based on the additional marker, compounds except essence and tobacco shred components are selected as the additional marker, the uniformity of the cigarette flavoring process can be evaluated more objectively, scientifically and accurately in a quantified mode, and the method has very important significance in evaluating the tobacco shred makingprocess and stabilizing the product quality.

Description

technical field [0001] The invention belongs to the technical field of tobacco performance evaluation, and relates to a method for detecting flavoring uniformity of cigarettes based on externally added markers. Background technique [0002] Based on comprehensive literature research, it is found that there have been some reports on the quantitative research on the uniformity of adding and flavoring processes inside and outside the tobacco industry in recent years, and most of them select one or a few flavor components as markers. [0003] The invention patent with the application number 201210172531.X discloses "a method for evaluating the uniformity of burley tobacco treatment and feeding based on xylitol detection". Through the analysis of the chemical components of the tobacco leaves before and after burley tobacco feeding, it is determined that the chemical composition that characterizes the uniformity is Xylitol, Xylitol is used as the target component of analysis, and ...
