Abstract
The invention relates to a method for characterizing monomer tobacco style characteristics based on tobacco aromatic components, and belongs to the technical field of tobacco quality evaluation. The method comprises the following steps: a, comparing and analyzing the aroma characteristics of various varieties by utilizing a radar chart, wherein in the radar chart, each data has an independent single numerical shaft, coordinate axes are distributed around the centre point radially, and the points of the value of the same data sequence on different coordinate axes are connected by fold line, so as to form the radar chart which is used for comparing the overall conditions of a plurality of data sequence indexes; and b, detecting aromatic components of different varieties in the same region, and performing multiple comparison on the contents of the aromatic components, so as to detect the differences of each variety with other varieties between various processes; and eliminating indistinctive indexes, and finding out the material basis causing aroma differences between varieties from the contents of the aromatic components. By utilizing the method, the quantitative and objective characterization of various aroma indexes of cured tobaccos is realized, and a material basis for deciding the aroma characteristics of tobaccos is found out.

Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, and a kind of method that characterizes monomer tobacco leaf style and features based on the tobacco leaf aroma component is provided.
Method based on tobacco leaf aroma component sign monomer tobacco leaf style and features of the present invention, concrete steps are as follows:
A. identify by the sensory evaluating smoking that contrast characterizes the calibration sample of note power, and the tobacco leaf note that sensory evaluation goes out is quantitatively composed branch; That is: adopt radar map to come the note characteristics of each kind of comparative analysis, in radar map, each data all has an independently single number line, coordinate axis is distributed in around the central point radially, it is exactly radar map that the point of the value of same data sequence on different coordinate axis coupled together formed polygon with broken line, be used for the comparison several number according to the general status of sequence indicator, and the assignment of each index illustrates that the closer to the center of circle these note characteristics are more outstanding; Otherwise, illustrate that then the note characteristics are the most outstanding;
B. same kind aroma component is from different places detected, content to aroma component compares again, to check between each handles---every kind and other kind difference between in twos, reject inapparent index, seek the material base that causes note difference between kind from flavor matter content aspect.
The foundation of the inventive method, for providing a kind of, the evaluation of flue-cured tobacco note feature characterizes with radar map, can carry out quantitative analysis to flue-cured tobacco note feature, solving flue-cured tobacco note feature can only qualitative description and can not quantitative comparison and by qualitative problem to quantitative conversion, has realized the various note indexs of objective sign flue-cured tobacco; By note score value and the correlation analysis of aroma component content, find out the material base of decision tobacco leaf note feature to tobacco leaf.
The sample of the inventive method analysis can expand to other type tobacco leaf, as: burley tobaccos, Turkish tobaccos.
Description of drawings:
Fig. 1 shows the main note feature of NC297.
Fig. 2 shows NC102 note feature.
Fig. 3 shows red big note feature.
Fig. 4 shows K326 note feature.
Embodiment:
The present invention is described further below in conjunction with concrete embodiment, but is not restriction the present invention.
Kind NC102, NC297 note signature analysis draw in 1 U.S.A
Adopt radar map to come the note characteristics of each kind of comparative analysis, see Fig. 1,2,3 and 4.In radar map, each data all has an independently single number line, coordinate axis is distributed in around the central point radially, it is exactly radar map that the point of the value of same data sequence on different coordinate axis coupled together formed polygon with broken line, is used for the general status of comparison several number according to sequence indicator.The assignment of each index illustrates that the closer to the center of circle these note characteristics are not outstanding more; Otherwise, illustrate that then the note characteristics are the most outstanding.
Know that by Fig. 1 the note of NC297 is mainly with delicate fragrance, fragrant and sweet, Jiao Tianwei master, and fresh and sweet and sweet sense is more outstanding, but the fragrance of a flower and Xin Xiang are not outstanding.
Know that by Fig. 2 the note of NC102 is mainly abundanter based on fragrant and sweet, delicate fragrance and burnt odor, fruital, but the banksia rose and the fragrance of a flower are outstanding.
Know that by Fig. 3 red big note is mainly with delicate fragrance, fragrant and sweet, Jiao Tianwei master, and the banksia rose is comparatively outstanding, but hay is fragrant and the fragrance of a flower is not outstanding.
Know by Fig. 4, K326 mainly based on delicate fragrance, burnt odor and fragrant and sweet, fruital than horn of plenty, but hay is fragrant and hot perfume (or spice) is not given prominence to.
2 aroma component analyses
The flavor matter composition is a lot of in the flue-cured tobacco, the contribution of tabacco fragrance is had nothing in common with each other, though some content of material is not high, can be the important source of some characteristic perfume.The flavor matter of flue-cured tobacco is the important chemical composition that is used for the tabacco fragrance evaluation study at present, also is one of important indicator that tobacco incense makings, perfume quantity and odor type style are estimated
[3-7]By same kind aroma component is from different places contained amount comparing analysis, seek the material base that causes note difference between kind from flavor matter content aspect.
Aroma component among red big, NC297, NC102 and the K326 is detected, 70 kinds of identical aroma components (seeing Table 1) are wherein arranged, content to these 70 kinds of aroma components carries out multiple ratio, to check between each handles---every kind and other kind difference between in twos, reject inapparent index gained and the results are shown in Table 2.Have the content of 28 kinds of aroma components to reach the level of signifiance in the table 2, wherein the letones large percentage has 13 kinds, secondly has 4 kinds for alcohols.
Flavor matter average content (μ g/g) in table 1 red big, NC297, NC102 and the K326 sample
Table 2 aroma component content multiple ratio is (μ g/g)
Annotate: under 0.05 level of signifiance.
From table 2, NC297 has the content of 17 kinds of flavor matters to reach the level of signifiance with red big the comparing with K326 of reference substance kind; Find that to NC297 flavor matter content analysis the time some can make the more outstanding flavor matter content of delicate fragrance note be higher than even are significantly higher than other kinds, as firpene, linalool, and phenylethyl alcohol.
NC102 has the content of 13 kinds of flavor matters to compare (red big and K326) with 2 reference substance kinds to have reached the level of signifiance.Some flavor matter content such as geraniol are significantly higher than the content of other 3 kinds among the NC102, and these flavor matters are the more outstanding reasons of fragrant and sweet rhythm.The content of some flavor matters such as the citrene among the NC102, benzaldehyde is higher to be to cause the reason of its fruital note than horn of plenty.Class content of material such as red big-and-middle guaiacol are significantly higher than NC102, and this is the reason that causes the red big banksia rose more more outstanding than NC102.
NC102 and NC297 are bigger and the K326 hay is fragrant outstanding than red, and some can make the fragrant flavor matter content of giving prominence to higher relevant (as gamma-valerolactone) of hay with gamma-valerolactone.
