Problems solved by technology

Although this method has certain positive effects, the evaluation of aroma characteristics based on sensory evaluation is easily affected by the personal factors of the smokers and the external environment, which will bring uncertain factors to the evaluation results of cigarettes.
Therefore, based on the aroma components of shredded tobacco, using instrumental analysis and detection methods, combined with correlation analysis technology, to extract characteristic indicators or compounds that have a key impact on the aroma characteristics of cigarettes from numerous chemical components, so as to achieve an objective analysis of the aroma characteristics of cigarettes. , accurate evaluation is particularly important, but there is no good solution in the prior art

Embodiment 1

[0022] Example 1: ----- Characterize the sweet aroma characteristics of ZH brand cigarettes:

[0023] (1) According to the relationship between the sweet and aroma characteristics of cigarettes and the aroma components of shredded tobacco, and combined with the production pathway of sweet and aroma, 10 representative sweet and aroma substances were determined: 1-penten-3-one, 2- Methoxy-phenol, eugenol, dehydronornicotine, coumarin, 3-(1-methylethyl)(1H)pyrazolo[3,4-b]pyrazine, tetradecaldehyde , neophytadiene, palmitic acid, ethyl palmitic acid;

[0024] (2) Calculate the correlation coefficient r between the sweet aroma score and the 10 characteristic substances i or r j , the calculation results are shown in Table 1;

[0025] Among them, the score of sweet aroma is the score of sweet aroma obtained after cigarette sensory quality evaluation according to the provisions of "GB5606.4-2005 Cigarette Sensory Technical Requirements".

[0026] The correlation coefficient r i ...

Embodiment 2

[0055] Example 2 - characterizing the sweet aroma characteristics of HHL brand cigarettes:

[0056] Repeat Example 1, with the following differences:

[0057] (1) According to the requirements of "Determination of Aroma Components of Tobacco and Tobacco Products Simultaneous Distillation and Extraction-Gas Chromatography / Mass Spectrometry" TCJC-ZY-IV-014-2012, the actual content of each characteristic substance was determined for the aroma components of HHL brand cigarettes , and the measurement results are shown in Table 6;

[0058] Table 6 Content of characteristic substances per gram of shredded tobacco of HHL brand cigarettes (unit: μg)

[0059]

[0060] (2) Calculate the index value P of each characteristic substance in HHL brand cigarettes i or G j , the characteristic substance index value is the relative content of each characteristic substance per gram of shredded tobacco, and the results are shown in Table 7.

Embodiment 3

[0064] Example 3 - characterizing the sweet aroma characteristics of BS brand cigarettes:

[0065] Repeat Example 1, with the following differences:

[0066] (1) According to the requirements of "Determination of Aroma Components of Tobacco and Tobacco Products Simultaneous Distillation and Extraction-Gas Chromatography / Mass Spectrometry" TCJC-ZY-IV-014-2012, the actual content of each characteristic substance was determined for the aroma components of BS brand cigarettes , and the measurement results are shown in Table 8;

[0067] Table 8 Contents of characteristic substances per gram of shredded tobacco in BS brand cigarettes (unit: μg)

[0068]

[0069]

[0070] (2) Calculate the index value P of each characteristic substance in BS brand cigarettes i or G j , the characteristic substance index value is the relative content of each characteristic substance per gram of shredded tobacco, and the results are shown in Table 9.

Abstract

The invention discloses a method for characterizing fragrant and sweet aroma characteristics of cigarettes by adopting an index. The method comprises the following steps: selecting 10 types of cigarette fragrant and sweet characteristic substances with representativeness from aroma components of cut tobaccos; calculating to find out characteristic substances with positive influences and negative influences on fragrant and sweet aroma respectively, and determining weights of characteristic substance indexes according to influence degrees; carrying out determination and analysis on the aroma components of the cut tobaccos of the finished-product cigarettes by adopting a Simultaneous Distillation and Extraction-Gas Chromatography / Mass Spectrograph for Determination of Aroma Components of Tobaccos and Tobacco Products; and finally, calculating a fragrant and sweet aroma index SWI of the finished-product cigarettes by adopting a weighting counting method. The index can be used for directly characterizing the intensity of the fragrant and sweet aroma characteristics of the cigarettes and has an objective and accurate evaluation result. The method is simple and convenient to operate, has low cost, and provides a new concept for quality maintenance and quality control of the cigarettes.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for characterizing the sweet, fragrant and aroma characteristics of cigarettes by using an index. Background technique [0002] Aroma characteristics are the unique flavor of cigarettes, the characteristics and logo of a cigarette brand, one of the important basis for consumers to choose cigarettes, and the premise of guiding consumption. The aroma of cigarettes has always been one of the important criteria for people to evaluate the quality of cigarettes. Studies have shown that the chemical components in cigarettes play a key role in the sensory quality and aroma characteristics of cigarettes, and the increase or decrease of key aroma-inducing substances in shredded tobacco is closely related to the change of cigarette aroma quality. [0003] At present, the evaluation of the aroma characteristics of cigarettes at home and abroad generally adopt...
