Description
Technical field
The present invention relates to the measuring method of potpourri, be specifically related to the proportioning detection method of flavouring essence for tobacco.
Background technology
Flavouring essence for tobacco is a kind of multicomponent chemical system of complexity, and is formulated by plurality of raw materials and an amount of solvent mediation, is subjected to multiple factor affecting such as raw material, processing technology, processing environment, only is difficult to its inherent quality is effectively supervised from its physical index.Essence in the cigarette produces special influence to the cigarette smell, is an important indicator of smoker's evaluation cigarette.Common way is to measure physical and chemical indexs such as acid number, relative density, refraction index and molten mixed degree to come quality monitoring according to YC/T 145-1998 industry series standard method at present.In the cigarette product production run, a kind of essence of cigarette product often has the essence of several different trades mark to have by artificial allotment by certain proportioning to form, therefore just might cause the ratio of cigarette essence to allocate unsettled phenomenon, thereby have influence on the quality stability of cigarette product, so the stability of monitor closely flavor deployment ratio has vital role for stable roll smoke product quality.Common way is with vapor-phase chromatography the essence of the different trades mark used in the cigarette essence to be analyzed by identical chromatographic condition earlier at present, find out the bigger endemic element of content in the different trade mark essence, use the relative proportioning of different trade mark essence in the internal mark method determination cigarette essence then.This way exists because the response difference of different chemical composition on gas chromatography detector is big, can't detect actual true proportioning, and analysis time problem such as length, process more complicated, detection complex steps, can't realize field quick detection.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the detection method of the actual real proportioning situation that solves the reflection flavouring essence for tobacco is provided.
For solving above-mentioned technical matters, the present invention by the following technical solutions:
A kind of method of quick measurement cigarette essence proportioning, be order through step 1 to step 5:
Step 2 is got essence sample for tobacco to be measured, with the solvent dilution of no uv absorption;
The uv absorption spectra of the essence sample for tobacco to be measured that the uv absorption spectra of the standard specimen that step 3 measuring process 1 is prepared and step 2 are prepared;
Absorbance corresponding under the uv absorption spectra of the standard specimen that step 4 usefulness obtains and the uv absorption spectra all wavelengths of essence sample for tobacco to be measured is as the independent variable matrix, as the dependent variable matrix, make up operation matrix with the proportioning ratio of different trade mark essence in the flavouring essence for tobacco;
Step 5 with the standard specimen in the step 1 as the initial reference sample, with polynary curve resolution-alternately least square method is carried out computing to the matrix in the step 4, obtains the actual proportioning of different trade mark essence in the testing sample.
Further technical scheme is the wavelength coverage of the UV scanning when gathering essence sample uv absorption spectra: 210～400nm, wavelength interval 1nm; Quartz colorimetric utensil light path: 1.0cm.
Further technical scheme be when measuring uv absorption spectra in the step 4 parameter, environmental facies with.
Further technical scheme is to be between 1: 50 to 1: 100 with the mass ratio behind the solvent dilution of each flavouring essence for tobacco and no uv absorption in step 1, the step 2.
Further technical scheme is that the solvent of no uv absorption is the potpourri of one of water, ethanol, isopropyl alcohol or water, ethanol, isopropyl alcohol in step 1, the step 2.
Compared with prior art, the invention has the beneficial effects as follows to detect and reflected the true proportioning situation of flavouring essence for tobacco that the detecting instrument of use is few, method is simple, can field quick detection.

Embodiment
Below the present invention is further elaborated.
Select one for use by 3 kinds of trade mark A, trade mark B and trade mark C essence and solvent composition flavouring essence for tobacco are example, measure the 1 actual trade mark A to testing sample 5 in the testing sample, the proportioning value of trade mark B and trade mark C essence through step 6 to step 10.
Step 6 is got flavouring essence for tobacco trade mark A, and trade mark B and trade mark C essence sample are respectively got the 50% ethanol water dilution of 1 gram with no uv absorption as standard specimen, and dilution ratio all is 100 times;
Step 7 is got essence sample for tobacco 1 to be measured, survey essence sample for tobacco 2, survey essence sample for tobacco 3, is surveyed respectively 1 gram of essence sample for tobacco 4, essence sample for tobacco to be measured 5, uses 50% ethanol water of no uv absorption to dilute, and dilution ratio all is 100 times;
The uv absorption spectra of the standard specimen that step 8 measuring process 6 is prepared, the uv absorption spectra of trade mark A is seen Fig. 1, and the uv absorption spectra of trade mark B is seen Fig. 2, and the uv absorption spectra of trade mark C is seen Fig. 3.Essence sample 1 in the measuring process 7 is to essence sample for tobacco 5 to be measured, and essence sample 1 to be measured to the uv absorption spectra of essence sample for tobacco 5 to be measured that correspondence obtains sees that Fig. 4 is to Fig. 8.
Absorbance corresponding under the uv absorption spectra of the standard specimen that step 9 usefulness obtains and the uv absorption spectra all wavelengths of essence sample for tobacco to be measured is as the independent variable matrix, as the dependent variable matrix, make up operation matrix with the proportioning ratio of different trade mark essence in the flavouring essence for tobacco;
