Flue-cured tobacco aroma type and quality judgment intelligent evaluation method

Abstract

The invention relates to a flue-cured tobacco aroma type and quality judgment intelligent evaluation method. The method is characterized by screening out aroma classification and aroma score principal component factors from tobacco aroma substances through a GRRF method; establishing a tobacco aroma style judgment model through GRRF+SVM and GRRF+RF methods; analyzing evaluation performance of the two methods through a 10 fold cross-validation method, wherein for classification evaluation results, adopting accuracy ACC and receiver operating characteristic curve as evaluation criterion, and for regression evaluation results, adopting Pearson's correlation coefficient and mean square error as evaluation criterion, and determining an optimal plan of a tobacco aroma type judgment model; and on the basis of the above, constructing a tobacco aroma type judgment online tool and carrying out evaluation on the aroma type and quality of tobaccos to be detected. The method can carry out analysis and judgment on aroma type characteristics of the tobaccos in different ecological areas objectively and accurately.

Description

technical field [0001] The invention relates to the field of judging the flavor and quality of flue-cured tobacco, in particular to an intelligent evaluation method for judging the flavor and quality of flue-cured tobacco. Background technique [0002] Tobacco leaves are the main body of cigarette formula, and their quality and style directly determine the smoking characteristics of cigarettes. During the processing of cigarette products, different parts and different styles of tobacco leaf raw materials are required to form a relatively stable leaf group formula, and through the blending effect of auxiliary materials (tobacco essence, spices), the unique smoking characteristics of its own brand of cigarettes are formed. In this process, a stable cigarette style (smoking characteristics) is particularly important for the physiological satisfaction of smokers and the stable development of cigarette enterprises. Therefore, the evaluation and use of tobacco leaf style character...

Problems solved by technology

At present, the domestic cigarette industry enterprises have not yet formed a unified evaluation standard for the evaluation of the quality and style of tobacco leaves, and the evaluation standards for tobacco leaves are mostly affected by the style and characteristics of their own cigarettes

[0005] To sum up, the current method of evaluating the quality and aroma characteristics of tobacco leaves by manual smoking is highly susceptible to the influence of environmental and personal factors, which brings great difficulties to the evaluation and effective utilization of tobacco raw materials and the stability of cigarette quality and style characteristics in industrial enterprises. At the same time, to a certain extent, it has increased the harm to the health of the reviewers themselves.
