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: -----Characterizing the aroma and aroma characteristics of ZH brand cigarettes:

[0023] (1) According to the relationship between the alcohol aroma characteristics of cigarettes and the aroma components of shredded tobacco, combined with the production pathway of alcohol aroma, 14 representative alcohol aroma substances were determined: 2-methoxy-phenol, oxidized isofor ketone, 2,4-bis(1,1-dimethylethyl)-phenol, 2,3'-dipyridyl, dihydroactinolactone, macrostigmatrienone, tetradecaldehyde, methyl myristate Esters, benzyl benzoate, anthracene, sonarasetone, methyl linolenate, 3-methyl-1-butanol, phenylacetaldehyde;

[0024] (2) Calculate the correlation coefficient r between the aroma score of the wine and the 14 characteristic substances i or r j , the calculation results are shown in Table 1;

[0025] Among them, the score of bouquet and aroma is the score of booze and aroma obtained after the sensory quality evaluation of cigarettes smoked according to th...

Abstract

The invention discloses a method for representing bouquet fragrance features of cigarettes by adopting an index. The method comprises the following steps: selecting 14 representative cigarette bouquet fragrance feature substances from tobacco shred aroma components, respectively figuring out feature substances having positive influence and negative influence on bouquet fragrance by calculation, and determining the weight of feature substance indexes according to the influence degree; then, performing determination analysis on the cigarette shred aroma components by adopting Simultaneous Distillation and Extraction-Gas Chromatography / Mass Spectrometry for Detecting Aroma Components of Tobacco and Tobacco Products; and finally calculating the bouquet fragrance feature index BI of a finished product cigarette by adopting a weighted statistic method. The index can be used for directly representing the strength of cigarette bouquet fragrance features, and has an objective and accurate evaluation result. The method is simple and convenient to operate, has low cost, and provides a new thought for quality maintenance and quality control of 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 booze 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...
