Embodiment 1

[0023] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for evaluating the alcoholization quality of tobacco leaves based on an electronic nose, comprising the following steps:

[0024] Step S1, using the electronic nose to collect the aging smell information of the sample tobacco leaves before burning and the burning smell information after burning;

[0025] Step S2, obtaining the sensory evaluation score of the sample tobacco leaf, and establishing the correspondence between the burning odor information and the sensory evaluation score, and the correspondence between the burning odor information and the aging odor information relationship, and then obtain the corresponding relationship between the alcoholized odor information and the sensory evaluation score;

[0026] Step S3, establishing an alcoholization quality evaluation model according to the corresponding relationship between the alcoholization odor information and the sensory evalua...

Embodiment 2

[0061] Such as figure 2 As shown, Embodiment 2 of the present invention provides a tobacco leaf aging quality evaluation system based on an electronic nose, including an electronic nose 1 and an evaluation terminal 2;

[0062] The electronic nose 1 is used to collect the alcoholization smell information of the sample tobacco leaves before burning and the burning smell information after burning;

[0063] The evaluation terminal 2 is used to obtain the sensory evaluation score of the sample tobacco leaf, and establish the corresponding relationship between the burning odor information and the sensory evaluation score, and the burning odor information and the aging odor information The corresponding relationship between, and then obtain the corresponding relationship between the alcoholized smell information and the sensory evaluation score;

[0064] The evaluation terminal 2 is also used to establish an alcoholization quality evaluation model according to the corresponding rel...

Abstract

The invention discloses a tobacco leaf alcoholization quality evaluation method based on an electronic nose. The method comprises the following steps that S1) the electronic nose is used to collect alcoholization smell information before combustion of sample tobacco leaves as well as combustion smell information after combustion; S2) a sense organ smoke panel test score of the sample tobacco leaves is obtained, correspondence between the combustion smell information and sense organ smoke panel test score is established, correspondence between the combustion smell information and the alcoholization smell information is also established, and further correspondence between the alcoholization smell information and sense organ smoke panel test score is obtained; S3) an alcoholization quality evaluation model is established according to the correspondence between the alcoholization smell information and sense organ smoke panel test score; and S4) the electronic nose detects to-be-detected alcoholization smell information of the to-be-detected tobacco leaf, and obtains an alcoholization quality score of the tobacco leaf to be detected by combining the alcoholization quality evaluation model. The method and system have the advantages of high detection efficiency, simple operation steps and subjective evaluation.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf alcoholization evaluation methods, in particular to a tobacco leaf alcoholization quality evaluation method and system based on an electronic nose. Background technique [0002] Tobacco leaves that have not been fermented have a variety of quality defects to varying degrees, with prominent green miscellaneous odor and irritation, no characteristic aroma of aged tobacco leaves, monotonous aroma, and insufficient aroma, so they cannot be directly used to produce cigarettes. After fermentation, the green miscellaneous gas and irritation of tobacco leaves are reduced, the characteristic aroma of tobacco is revealed, and the usability is improved. Therefore, tobacco leaves must be fermented before they can be used to produce cigarettes. [0003] At present, the main method for judging the alcoholization quality of tobacco leaves is sensory evaluation. It is difficult to carry out effectively, whi...
