Abstract
The invention discloses a method for accurately identifying flue-cured tobacco flavor types. According to the invention, a smoking and evaluating group is organized, wherein the members in the group are good at sensing the scents of flue-cured tobaccos; 8 characteristic scent components are evaluated and quantified with a blind-review method, wherein the 8 scents are tobacco scent, fragrant scent, sweet scent, fruit scent, flower scent, spicy scent, wood scent, and coke scent; scent score data is adopted as a basis, and a flavor style characteristic profile diagram is drawn; with the profile diagram as a basis, flue-cured tobacco scent area index S is obtained with a calculation formula S=1/2*sinC*a*b, wherein a and b are two adjacent flavor style characteristic values, and C is an included angle of a and b. If S is smaller than 25.0, the flue-cured tobacco is strong-flavored flue-cured tobacco. If S is 26.0-30.0, the flue-cured tobacco is middle-flavored flue-cured tobacco. If S is greater than 30.0, the flue-cured tobacco is light-flavored flue-cured tobacco. The flue-cured tobacco flavor type identifying method provided by the invention is practicable, accurate, convenient, and visual.
Description
Technical field
The invention belongs to cigarette determination techniques field, be specifically related to a kind of method of accurate evaluation flue-cured tobacco odor type.
Background technology
The flue-cured tobacco odor type is the important evidence that quality of tobacco evaluation and cigarette composition are used, and as far back as the sixties in 20th century, Zhu Zunquan, Wang Chenghan etc. just is divided into delicate fragrance type, middle odor type, Luzhou-flavor three big odor types with China's tobacco leaf.But these three kinds of odor types of criticism cured tobacco leaf raw material for how still do not have the criticism method of system so far.Based on this, the criticism of flue-cured tobacco odor type is classified as one of primary study content in the great special characteristic sound tobacco exploitation of State Bureau " the three vertical three horizontal strokes " project.In recent years; People are on the basis of aesthetic quality's criticism and characteristic component analysis thereof; Made up flue-cured tobacco odor type discriminant function, but because the characteristic component that influences flue-cured tobacco fragrance style that obtains of analysis difference to some extent, so the discriminant function of the evaluation flue-cured tobacco odor type that Different researchers obtains is also different; To the qualification result of flue-cured tobacco odor type also difference to some extent, it is comparatively time-consuming, expensive that these methods analysts detect flue-cured tobacco fragrance style and features compositions in addition.So, set up a kind of objective, accurate, practical, flue-cured tobacco odor type authentication method extremely is necessary easily.
Summary of the invention
The objective of the invention is to deficiency, a kind of method of accurate evaluation flue-cured tobacco odor type is provided to prior art.On the basis of sense organ criticism flue-cured tobacco note, through calculating the note area index, and then identify the odor type of flue-cured tobacco fast and accurately.
The object of the invention is realized through following technical scheme.
A kind of method of accurate evaluation flue-cured tobacco odor type may further comprise the steps:
1, flue-cured tobacco note criticism: adopt by sensory evaluating smoking technician and secretly to comment mode, strong and weak according to note, perfume of the tobacco in the flue-cured tobacco to be evaluated, delicate fragrance, fragrant and sweet, fruital, the fragrance of a flower, Xin Xiang, the banksia rose and 8 kinds of characteristic notes of burnt odor component are evaluated and quantized; Every kind of note is divided into 6 class: outstanding, outstanding, obviously, obviously, have and do not have, and distinguish scoring value 10 minutes, 8 minutes, 6 minutes, 4 minutes, 2 minutes and 0 minute;
2, be the basis with fragrance style and features data, draw the fragrance style and features profile diagram of flue-cured tobacco to be evaluated;
3, with the profile diagram be the basis, calculate according to formula S=1/2*sinC*a*b and obtain flue-cured tobacco note area index S to be evaluated; In the formula, a, b are adjacent two fragrance style and features values, and C is the angle of a, b;
4, carry out the cured tobacco leaf odor type according to the note area index S value that calculates and judge, if S＜25.0 then are the Luzhou-flavor flue-cured tobacco; If S is 25.0～30.0, then be middle odor type flue-cured tobacco; If S＞30.0 then are the delicate fragrance type flue-cured tobacco.
With respect to prior art, the present invention has the following advantages:
1, more direct.The sensory evaluating smoking has solved the complex physical perception issue that general physico-chemical analysis cann't be solved, and reflects the style and features and the quality characteristic of tobacco leaf the most directly, truly;
2, more directly perceived.Through observing fragrance style and features profile diagram, can tell the fragrance style and features of three kinds of odor type tobacco leaves intuitively;
3, simpler and more direct.Just can differentiate the tobacco leaf odor type simply, easily according to note area index size.
Description of drawings
Fig. 1～Figure 24 is respectively the note profile diagram of sample A1～A24 among the embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description, but accompanying drawing and embodiment are not the qualification to protection domain of the present invention.
Embodiment 1～24:
(1) 11 in tissue is good at the sensory evaluating smoking personnel of perception flue-cured tobacco note, adopts and secretly to comment mode, describes with reference to odor characteristic index in the table 1, the note of cured tobacco leaf sample A1～A24 is carried out criticism, and quantize score, and the result sees table 2.
Table 1 flue-cured tobacco note component characteristics index is described
Table 2 cured tobacco leaf sample note criticism result
(2) according to cured tobacco leaf sample A1～A24 note criticism quantized result, draw the note profile diagram, see Fig. 1～Figure 24.
(3) according to the note profile diagram of Fig. 1～Figure 24, obtain the note area index of flue-cured tobacco sample A1～A24 according to computing formula (1), the result sees table 3.
S＝1/2*sinC*a*b...............................................................(1)
Wherein, a, b are adjacent two fragrance style and features values, and C is the angle of a, b.
Table 3 flue-cured tobacco sample note area index and odor type result of determination
(4) according to judgment basis: if note area index S＜25.0 then are the Luzhou-flavor flue-cured tobacco; If note area index S is 25.0～30.0, then be middle odor type flue-cured tobacco; If note area index S＞30.0 then are the delicate fragrance type flue-cured tobacco.In 24 samples of institute's criticism, A1～A6 is the flue-cured tobacco Luzhou-flavor, is respectively the tobacco leaf of Henan, Hunan and Zimbabwe; A7～A10 is an odor type in the middle of the flue-cured tobacco, is respectively the tobacco leaf in Heilungkiang and Guizhou; A11～A24 is the flue-cured tobacco delicate fragrance type then, is respectively Sanming City, Fujian and Yunnan tobacco, 3 kinds of odor type qualification results be consistent with the odor type of traditional place of production flue-cured tobacco (seeing table 3).
