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 spicy and aroma characteristics of ZH brand cigarettes:

[0023] (1) According to the relationship between the spicy aroma characteristics of cigarettes and the aroma components of shredded tobacco, combined with the production pathway of spicy aroma, 9 representative spicy aroma substances were determined: isopentyl isovalerate, macrostigatietriene Ketone, methyl myristate, methyl palmitate, ethyl palmetate, phenylacetaldehyde, ethyl maltol, eugenol, triethyl citrate;

[0024] (2) Calculate the correlation coefficient r between the spicy aroma score and the 9 characteristic substances i or r j , the calculation results are shown in Table 1;

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

[0026] The correlation coefficient r i or r j is through the formula c...

Embodiment 2

[0056] Example 2 - characterizing the spicy and aroma characteristics of HHL brand cigarettes:

[0057] Repeat Example 1, with the following differences:

[0058] (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;

[0059] Table 6 Content of characteristic substances per gram of shredded tobacco of HHL brand cigarettes (unit: μg)

[0060]

[0061] (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.

[0062] Table 7 Relative content of characteri...

Embodiment 3

[0065] Example 3 - characterizing the spicy aroma characteristics of HH brand cigarettes:

[0066] Repeat Example 1, with the following differences:

[0067] (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 HH brand cigarettes , and the measurement results are shown in Table 8;

[0068] Table 8 Content of characteristic substances per gram of shredded tobacco of HH brand cigarettes (unit: μg)

[0069]

[0070] (2) Calculate the index value P of each characteristic substance in HH 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.

[0071] Table 9 Relative Contents of Characteristic Su...

Abstract

The invention discloses a method for characterizing cigarette spicy aroma characteristic by using index. The method is as below: selecting 9 representative cigarette spicy aroma characteristic substances from tobacco aroma components; calculating and finding characteristic materials with positive influence and negative influence on the spicy aroma; the determining the weights of the characteristic material indexes according to the degree of influence; then determining and analyzing the tobacco aroma components in finished cigarette according to the simultaneous distillation and extraction-gas chromatography-mass spectrometry method for determination of aroma components in tobacco and tobacco products; and finally, calculating the spicy index SI of finished cigarette by a weighted statistical method. The index can visually characterize the intensity of cigarette spicy aroma characteristic, and the evaluation results are objective and accurate. The invention has the advantages of simple operation and low cost, and provides a new idea for the quality maintenance and quality control of cigarette.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for characterizing the spicy 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 adopts the sens...
