[0003] For the evaluation of cigarette style characteristics, the tobacco industry has established a corresponding evaluation standard YC / T497-2014 "Sensory Evaluation Method for Cigarette Chinese Style Cigarette Style". Applying the method stipulated in this standard can carry out quantitative evaluation of 15 flavor types of cigarettes, and can also Using the radar chart to obtain the corresponding evaluation result chart, but it is difficult to intuitively analyze the similarity of the quality characteristics of different products based on the quantitative results and the radar chart

The invention discloses a star graph identification method for cigarette quality characteristics. The method comprises following steps: step 1. sensory evaluation data is obtained; step 2: the sensory evaluation data of cigarettes is read in Matlab software and is pretreated by using a certain data normalization method; step 3: cigarette sample star graphs are drawn by using the pretreated data; step 4. the samples are classified on the basis of similarities among the cigarette sample star graphs; step 5. the star graphs are compared and observed, prominent characteristics of each star graph class are analyzed, main flavor note characteristics of each class of samples are determined. According to the method, twelve quality characteristics of Chinese style cigarettes are made to correspond to the star graphs so that the sensory evaluation results of cigarettes are presented through star graphs. The advantages of the method are: the star graphs are vivid and visual and vividly visualize flavor type and flavor note characteristics of cigarettes as star-shaped characteristics; the similarity and difference of the flavor type and flavor note characteristics of cigarette products are analyzed visually so that the requirements of cigarette product comparison and analysis and category construction are met.
Description
technical field [0001] The invention belongs to the technical field of cigarette sensory evaluation, and in particular relates to a star graph recognition method for quality characteristics of cigarettes. Background technique [0002] Cigarettes are a special product for human consumption. Since the final form of consumption of cigarette products is smoking, the style, characteristics and flavor quality of cigarettes must be burned to provide consumers with feelings. Therefore, the most direct, timely and most representative of consumers' will is the sensory analysis and evaluation of cigarettes. . The overall task and purpose of cigarette sensory analysis and evaluation is to determine and describe the level of flavor quality and style characteristics, and to provide effective and reliable information for product developers and marketing personnel to make correct product and market decisions. Due to market demand and product development, analysis and evaluation of cigaret...
