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 fragrance and aroma characteristics of YY brand cigarettes:

[0023] (1) According to the relationship between the aroma characteristics of cigarettes and the aroma components of shredded tobacco, and combined with the production pathway of the aroma, 12 representative characteristic substances were determined: 6-methyl-5-hepten-2-one, benzene Ethanol, triethyl citrate, benzaldehyde, 5-methylfurfural, menthol, damascenone, macrostigmatrienone, methyl myristate, myristic acid, methyl palmitate, palmitic acid;

[0024] (2) Calculate the correlation coefficient r between the fragrance score and the 12 characteristic substances i or r j , the calculation results are shown in Table 1;

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

Abstract

The invention discloses a method for representing the clean aroma characteristics of cigarettes with indexes. The method includes the steps that 12 kinds of representative cigarette clean aroma characteristic substances are selected from cut tobacco aroma components, characteristic substances having positive influences and negative influences on the clean aroma are found out respectively through calculation, and the weights of characteristic substance indexes are determined according to the influence degrees; then, the cut tobacco aroma components of the finished cigarettes are measured and analyzed through the simultaneous distillation extraction-gas chromatography / mass spectrometry method for measuring aroma components of tobacco and tobacco products; finally, the clean aroma characteristic index GI of the finished cigarettes is calculated through the weighted statistics method. The index can visually represent the strength of the clean aroma characteristics of the cigarettes, and the evaluation result is objective and accurate. The method is easy and convenient to implement and low in cost and provides new ideas for cigarette quality maintenance and quality control.

Description

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