Analysis detection 1：Sensory quality assessment

The tobacco extract of Example 1~4 and comparative example 1, respectively equivalent be applied on the cigarette paper of blank cigarette, apply The amount of smearing accounts for 2/10000ths of cigarette weight, and gained cigarette sample number consecutively is A~E.According to standard YC/T498-2014《Reconstruction Tobacco leaf (paper process) sensory evaluation method》Sample evaluation rule, aesthetic quality is carried out to cigarette A~E and is smoked panel test, as a result such as table 1 It is shown.

1 cigarette sample aesthetic quality's grade form of table

As shown in Table 1, the sense organ marking of cigarette E is 68.0 points, and the sense organ marking of cigarette A~D is 69.0~72.5 points.Tool Body, cigarette A~D is promoted in terms of perfume quantity and sweet sense, and cigarette A~C further decreases in terms of irritation, Cigarette A~B is further promoted in terms of aroma quality, is decreased in terms of withered and burnt smell, wherein, the marking highest of cigarette A, Its aroma quality, perfume quantity and sweet sense rising are most apparent, and withered and burnt smell reduces most notable.It is described above, the tobacco of Examples 1 to 4 Extract be used for cigarette, can effectively promote aroma quality, perfume quantity and/or the sweet sense of cigarette, reduce cigarette irritation and/ Or withered and burnt smell, improve Sensory Quality of Cigarette.

Analysis detection 2：Gaschromatographic mass spectrometry detects

It is respectively caused in gas chromatography mass spectrometry (GC/MS) further detection 1 two groups of tobacco extracts of embodiment 1 and comparative example Fragrant ingredient.

To meet detection sample requirement, the tobacco of embodiment 1 and comparative example 1 is extracted respectively with dichloromethane (polarity 3.4) Extract, add methylene chloride 200ml per 200ml tobacco extracts, extracts 3 times, merges and collects 3 extract liquor (dichloromethane Phase), 500ml is taken, is concentrated under reduced pressure (G3 Rotary Evaporators, Heidolph companies), 39 DEG C, vacuum degree 750mbar of thickening temperature, is turned After fast 110rpm/min, 2.0ml is concentrated into, obtains detection sample.

Gaschromatographic mass spectrometry condition is as follows：Chromatographic column DB-5MS (30m × 0.25mm × 0.25 μm)；Carrier gas He (99.999%)；Flow velocity 1.0ml/min；290 DEG C of injector temperature；1.0 μ L of sample size；Sample introduction pattern is split sampling；Shunting Sample introduction is than 10:1；Temperature program is 45 DEG C (2min), and 5 DEG C/min rises to 200 DEG C, and 3 DEG C/min rises to 250 DEG C, and 5 DEG C/min rises to 300℃(10min)；Ion source is electron bombardment (EI)；Electron energy 70eV；250 DEG C of ion source temperature.Transmission line temperature 300 ℃；Analyzer is level four bars mass analyzer；Scan pattern is full scan；40~500amu of mass scan range；Solvent delay 4.5min。

According to gaschromatographic mass spectrometry testing result, analyze and calculate tobacco extract obtained by every gram of tobacco leaf (oven dry weight) In several main aroma components mass content and ratio, it is as shown in table 2 below：

Table 2

As shown in table 2, compared to comparative example 1, main aroma component has increase in the leaf tobacco extract of embodiment 1.Example Such as, ethyl laurate extraction efficiency increases by 585.3%, and methyl linoleate extraction efficiency increases by 1859.5%, and 2-Methyl Butyric Acid carries Efficiency is taken to increase by 671.4%, isovaleric acid extraction efficiency increases by 259.2%.It should it follows that being used in tobacco leaf extraction process After additive, the extraction efficiency of main aroma component significantly improves.

In addition, for the normalization percentage of above-mentioned several main aroma components, embodiment 1 is compared with comparative example 1, sub- oil The ratio of sour methyl esters increases, and the ratio of ethyl laurate, 2-Methyl Butyric Acid and isovaleric acid decreases.It follows that make The tobacco extract prepared with present composition extraction not only increases the extraction efficiency of main aroma component, also optimizes master The ratio of aroma component is wanted, which is used for cigarette, can effectively promote aroma quality, perfume quantity and/or the sweet tea of cigarette Moisture feeling reduces the irritation and/or withered and burnt smell of cigarette, improves Sensory Quality of Cigarette.

Further, according to the detection data of gaschromatographic mass spectrometry, to each aroma component for detecting according to esters and organic Two class chemical composition of acids carries out Classifying Sum, and specifically, esters chemical composition includes ethyl laurate, methyl linoleate, second Acetoacetic ester and benzyl butyrate；Organic acid chemical composition includes：2-Methyl Butyric Acid, isovaleric acid and furancarboxylic acid.

Two class chemical composition contents and ratio comparison are as shown in table 3 below in the tobacco extract of embodiment 1 and comparative example 1.

Table 3

As shown in table 3, in the tobacco extract of embodiment 1, ester type compound extraction efficiency increases by 1029.1% in tobacco leaf, Organic acid compound extraction efficiency increases by 147.2%.From the foregoing, it will be observed that the tobacco extract prepared using the present composition, The content of two major class chemical composition of esters and organic acid is significantly increased in product.

In addition, for the normalization percentage of above-mentioned two major class chemical composition, embodiment 1 is compared with comparative example 1, esters The ratio for closing object increases, and the ratio of organic acid compound decreases.It follows that it is extracted using the present composition The tobacco extract of preparation not only increases the extraction efficiency of two major class chemical compositions, also optimizes the ratio of two major class chemical compositions Example, the tobacco extract are used for cigarette, can effectively promote aroma quality, perfume quantity and/or the sweet sense of cigarette, reduce cigarette Irritation and/or withered and burnt smell improve Sensory Quality of Cigarette.

For the composition that above-described embodiment uses, lipophilic group and hydrophily base are included in their chemical constitution Group, wherein, lipophilic group can be combined with liposoluble constituent in tobacco leaf, and hydrophilic radical can be combined with water, and then form water packet The physical form of oil, is dissolved in water liposoluble constituent in tobacco leaf.Tobacco is extracted from tobacco using the composition of the present invention Extract can not only improve the extraction efficiency to effective aroma component in tobacco and two major class chemical compositions, additionally it is possible to excellent Change the ratio of effective aroma component and two major class chemical compositions.The tobacco extract is used for cigarette, can effectively promote cigarette Aroma quality, perfume quantity and sweet sense reduce the irritation and withered and burnt smell of cigarette, improve Sensory Quality of Cigarette.

Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still It can modify to the specific embodiment of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair The spirit of bright technical solution should all cover in the claimed technical solution range of the present invention.
