Problems solved by technology

Finally, the use of tobacco flavors and fragrances is divided according to the single item score and the total score. Such a result is a direct summation of sensory scores, and the scores are extremely obscure, difficult to understand and analyze, and not intuitive enough
[0003] In order to make the evaluation results more intuitive, in the prior art, there is an overall cycle evaluation method or a three-point detection method, and the sensory evaluation index is scored on a 9-point scale; there is also a profile analysis method to construct cigarette style characteristics or a combination of chemical analysis methods. Detect the ingredients, and then use the mathematical model to evaluate the quality. However, the above methods still have the problems of complex sample processing, cumbersome detection steps, inaccurate model selection and index selection, and cannot accurately and truly reflect the quality of fragrance.
Moreover, for the evaluation of fragrance quality, how to reflect the fragrance quality most truly with the fewest indicators is also a difficult problem at present.

Embodiment 1

[0035] The fragrance quality evaluation method of the flavor and fragrance of the present embodiment, comprises the following steps:

[0036] Step (1), Manual Quality Evaluation

[0037] Spray the tender flavor and fragrance C# and its reference flavor and fragrance on shredded tobacco to prepare cigarette samples, and an evaluation team composed of 7 people evaluates the aroma characteristics of the cigarette samples according to the evaluation grades determined in Table 1;

[0038] Table 1 Evaluation grade of fragrance quality index

[0039]

[0040]

[0041] Among them, no difference, significant difference and slight difference are evaluated according to the fourth part of GB5606.4-2005 cigarettes - sensory technical requirements, and the relationship between sensory quality score and comment grade is shown in Table 3:

Embodiment 2

[0060] The fragrance quality evaluation method of the flavor and fragrance of the present embodiment, comprises the following steps:

[0061] Step (1), Manual Quality Evaluation

[0062] Spray the tender flavor and fragrance D# and its reference flavor and fragrance on shredded tobacco to prepare cigarette samples, and an evaluation team composed of 7 people evaluates the aroma characteristics of the cigarette samples according to the evaluation grades determined in Table 1;

[0063] Step (2), statistical evaluation results;

[0064] Count the number of people who select the evaluation grade of each fragrance quality index, and divide the number by the total number of evaluation groups to obtain the evaluation results, as shown in Table 5;

Abstract

The invention relates to a fragrance quality evaluation method for flavors and spices, and the method comprises the following steps: (1), manual quality evaluation; (2), statistical operation of an evaluation result; (3), the rewriting of the evaluation result at step (2) into a single-factor evaluation matrix; (4), the constructing of a weight matrix; (5), result evaluation. According to the method, there is no need to specifically score each index of flavors and spices calling for bids, and only the description of quality degree is required. The method innovatively takes the difference between two samples as the remarks, so the result is more visual and is reliable and stable, and is independent of a pure data result. A monomer perfume material evaluation method is employed for the flexible displaying of a fragrance quality evaluation result of flavors and spices of smoke, and is independent of a pure data result, so the method is high in operability and application value. Accordingto the invention, the result of the comprehensive index values is easier to understand, and is convenient for application.

Description

technical field [0001] The invention relates to a method for evaluating fragrance quality, in particular to a method for evaluating fragrance quality of flavors and fragrances. It belongs to the field of cigarette evaluation. Background technique [0002] Tobacco flavors and fragrances have an important impact on the style characteristics and sensory quality of cigarettes. At present, the qualitative quality of tobacco flavors and fragrances is mainly based on sensory evaluation, and the specific use direction of tobacco flavors and fragrances is determined based on sensory evaluation. However, flavor quality needs to consider multiple sensory indicators at the same time, and each indicator has different sub-indices. To evaluate a single tobacco flavor and fragrance, at least more than 10 indicators need to be scored. Finally, the use of tobacco flavors and fragrances is divided according to the single item score and the total score. The result is a direct summation of sens...
