Abstract
The invention discloses a flue-cured tobacco raw material sensory quality evaluation method applicable to mixed type cigarettes. The sensory quality evaluation method comprises ten evaluation indexes including aroma, aroma amount, miscellaneous gas, smoke concentration, strength, irritation, aftertaste, combustibility, gray and a controlling index, wherein the controlling index is a comprehensive index of tobacco raw materials applicable to the mixed type cigarettes. According to the sensory quality evaluation method, sensory evaluation of the quality of the flue-cured tobacco raw materials is quantified for the first time to judge the applicability in a mixed type cigarette leaf group formula; each index is graded according to nine points; aiming at the emphasis of the flue-cured tobacco raw material needed by the mixed type cigarettes, the weight of the final score of each index sub-item is different, the statistical total score is converted by a centesimal system and the weights of all the indexes are contained in the final score. The method is easy to operate, is simple and clear and can directly judge the applicability of the flue-cured tobacco raw materials.
Description
Technical field:
The present invention relates to a kind of flue-cured tobacco raw material sensory quality assessment method that is applicable to blended type cigarette, is a kind of sensory quality assessment method of differentiating targetedly flue-cured tobacco adaptability to raw materials.
Background technology:
It is that the generally acknowledged one of tobacco business is to raw tobacco material, finished cigarettes quality evaluating method that aesthetic quality smokes panel test, it is also the Main Basis of cigarette tobacco leaf formulation design, essence and the screening of feed liquid formula that sensory evaluating smoking evaluates, by the evaluation to tobacco leaf indices, can accurately directly judge the quality of quality of tobacco.The most frequently used flue-cured tobacco raw material sensory quality assessment is evaluated marking to the indices of tobacco leaf at present, again each index score simply added and calculate total score, the height of total score is representing the quality of cured tobacco leaf, but can not evaluate its applicability in cigarette tobacco leaf formulation, especially blended type cigarette tobacco leaf formulation, a for example tobacco leaf in Yunnan, sensory evaluation indices score is all very high, belong to the tobacco leaf of high-quality, but be not suitable in blended type cigarette.
Whether blended type cigarette tobacco leaf formulation is designed to merit, key is to require the suitable raw tobacco material of formula personnel selection, but blended type cigarette is different from Virginian-type cigarette to the selection of flue-cured tobacco raw material, the grade classification of China's flue-cured tobacco raw material is different at present, quantity is various, in order to improve tobacco leaf formulation design efficiency; Strengthen the compatibility of tobacco leaf formulation flue-cured tobacco and burley tobaccos, Turkish tobaccos, find a kind of easy method preliminary screening and go out blended type cigarette flue-cured tobacco raw material and become formula personnel's research direction, have not been reported but flue-cured tobacco raw material is applicable to the sensory quality assessment method of mixed type brand cigarette.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of flue-cured tobacco raw material sensory quality assessment method that is applicable to blended type cigarette, be a kind of easy realization, differentiation flue-cured tobacco raw material adaptability sensory quality assessment method easy and simple to handle, find adaptability to raw materials sensory evaluation method for other types cigarette simultaneously reference is provided.
Technical solution problem of the present invention adopts following technical scheme:
A flue-cured tobacco raw material sensory quality assessment method that is applicable to blended type cigarette, it comprises the following steps:
(1), fragrance matter, perfume quantity, assorted gas, flue gas concentration, strength, pungency, pleasant impression, flammability, grey, ten evaluation indexes of controlling indicator are set;
(2), evaluation method total score computing method, except other nine indexs of controlling indicator, carry out centesimal system according to nine points of system statistics marks and convert, it is as follows that ten indexs are calculated final score weights:
(a) sensory evaluating smoking of fragrance matter, perfume quantity, assorted gas, flue gas concentration, pungency, pleasant impression, flammability, grey is according to nine points of system scorings, be followed successively by from high to low 9,8,7,6,5,4,3,2,1, the minimum unit of scoring is 0.5 point, add up the arithmetic mean of every individual event, round up and retain a decimal; The integral part corresponding centesimal system of converting is followed successively by 100,90,80,70,60,50,40,30,20, decimal is directly multiplied by 10 and counts centesimal system mark, and the weight of calculating final score respectively is 0.15,0.20,0.25,0.10,0.05,0.10,0.03,0.02;
(b) sensory evaluating smoking of strength, according to nine points of system scorings, is followed successively by 9,8,7,6,5,4,3,2,1 from high to low, and the minimum unit of scoring is 0.5 point, adds up the arithmetic mean of every individual event, rounds up and retains a decimal; The integral part corresponding centesimal system of converting is followed successively by 60,80,100,90,70,50,40,30,20, and decimal is directly multiplied by 10 and counts centesimal system mark, and the weight that strength is calculated final score is respectively 0.10;
(c) controlling indicator is the comprehensive evaluation index of raw tobacco material and blended type cigarette tobacco leaf formulation compatibility, and this index is marked according to nine points of systems, is followed successively by from high to low 9,8,7,6,5,4,3,2,1; Corresponding weight is followed successively by 1.2,1.1,1.0,0.9,0.8,0.7,0.6,0.5,0.4;
(3), calculate total score according to formula 1
Y=K* ∑ (X
i* F
i) ... formula (1)
In formula: Y-total score; K-controlling indicator weight; X
i-each centesimal system score of converting of itemizing; F
ithe shared weight of-indices;
(4) total score of, calculating according to step (3) judges that the applicability of flue-cured tobacco raw material, Y >=70 are divided into that adaptability raw material, 50 points≤Y < 70 are divided into bases fit raw material, Y < 50 is divided into being not suitable for property raw material.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is based on traditional flue-cured tobacco sensory quality assessment method basis, the function of sensory evaluation breaks traditions, design a kind of sensory evaluation method that novel flue-cured tobacco raw material is applicable to mix cigarette tobacco leaf formulation, directly judged flue-cured tobacco raw material applicability in mixed type tobacco leaf formulation by Analyses Methods for Sensory Evaluation Results;
