Description
Technical field
The present invention relates to the evaluation of liquor, specifically, is the evaluation of carrying out the liquor kind with infra-red sepectrometry.
Background technology
The liquor of China can be divided into three kinds of Maotai-flavor, Luzhou-flavor and delicate fragrance types according to odor type.
Maotai-flavor liquor is a liquor most characteristic in the Chinese wine.Maotai-flavor liquor mainly originates in Chinese Guizhou Maotai Zhen, there natural conditions uniqueness, and Bie Juyige traditional handicraft makes the local flavor of Maotai-flavor liquor unusual in addition.
Yet the discriminating means of Maotai-flavor liquor mainly rely on subjective appreciation, promptly utilize people's sense organ-at a glance, nose, mouth comprehensively to judge the color of wine.This method makes liquor detect not enough science, standard owing to be subjected to objective, subjective condition influence.Chromatography has been widely used in liquor industry now, as the vapor-phase chromatography of the solid-phase microextraction vapor-phase chromatography that detects volatile compound, potpourri and high performance liquid chromatography gentle-the matter coupling, promoted quality of white spirit control.Yet liquor is made up of the complicated fragrance compound of hundreds of kind, chromatography is paid attention to liquor microcosmic The Chemical Constituents more, come and the combined action of the various self components of liquor and mutual relationship isolated, so chromatography is difficult to adapt to comprehensive, macroscopical overall evaluation of liquor.
In order to remedy the deficiency of chromatography in the liquor attributional analysis, we introduce the liquor analysis field to infrared spectrum technology first.Its ultimate principle: in the COMPLEX MIXED objects system, as long as its contained chemical constitution difference, the ratio difference of each component content all can cause the difference of infrared spectrum, just as " fingerprint " difference of people.We carry out the full constituent assay determination to the COMPLEX MIXED objects system, and the holistic approach of macroscopic view is under the prerequisite of the former person's character of not destroying it.The spectrum of a potpourri then is the stack spectral of its contained various compositions, constitutes macroscopic view " fingerprint " property of spectrogram.
What common infrared spectrum showed is that various composition infrared absorption always superpose and macroscopical fingerprint of formation in the liquor, and the main absorption peak of liquor concentrates on 1000cm
-1～3000cm
-1In the scope.Table 1 is the pointing out of main infrared absorption peak of 20 ℃ of liquor infrared spectrums in this scope of measuring down.
The main absorption peak of table 1 liquor infrared spectrum is pointed out
It is that the ir data that is obtained is carried out spectrum after differential is handled that the derivative of liquor is composed.It is to calculate the slope at each data point place and the curve that is unified into along the curve of spectrum.
Curve is the first order derivative spectrum,
Curve is a second derivative spectrum, and the rest may be inferred,
Curve is n order derivative spectrum.λ can be a wavelength, also can be wave number.
Derivative spectrum commonly used in the liquor analysis is a second derivative spectrum, and this has only former spectrum because of half-peak breadth in second derivative spectrum
Basically, reached the purpose that improves spectrogram resolution, although the half-peak breadth of quadravalence derivative spectrum reduces to former spectrum
The resolution of spectrogram is higher than second derivative spectrum, but it is higher to quality (low noise) requirement of former spectrum, and perhaps negative peak can be more outstanding.
Infrared analysis has distinct fingerprint characteristic.For a mixture system, the spectrum peak stack of contained various corresponding groups in the system is being represented at the peak shape of its molecular vibration spectrum, peak position, peak by force.The variation that potpourri is formed will directly cause the variation of the whole spectrogram of molecular vibration spectrum, but still can keep macroscopical fingerprint of its spectrogram.Utilize this macroscopical fingerprint, just can be directly or make mathematics slightly and handle after, be used for identifying and quality control.
1. non-destructive can accomplish not lose former person's character to the mensuration of sample.
2. easy, quick, sample be need not to handle, need not just can directly test through loaded down with trivial details separation and Extraction process.
3. robotization can be carried out onlinely with computing machine, realizes the robotization of liquor quality control.
4. instrument is comparatively general, and measurement operation is easy, is easy to apply.
5. needn't seek single, pure reference material specially
This method is easy, quick, and this method both can directly have been determined quality of white spirit and differentiate the falsification of distilled spirit quality, also can be used for analyzing and differentiating other aromatic white spirit.
Summary of the invention

(4) utilize common middle infrared spectrum and derivative spectrogram directly to obtain the finger-print region and the characteristic absorption peak of described aromatic white spirit.
Measure mid-infrared spectral method in the step 2, step is as follows:
(1) liquor to unknown its odor type carries out vacuum freezedrying, removes water and ethanol in the liquor;
(2) utilize the common middle infrared spectrum of mid-infrared light spectrometer working sample;
