Description
Technical field
The invention belongs to a kind of detection methods in white wine base liquor ageing time.It is specifically a kind of to utilize infrared spectroscopy pair
The detection method in Luzhou-flavor liquo base liquor ageing time.
Background field
White wine is one of a kind of distinctive Spirit in China and the big Spirit in the world six.Luzhou-flavor liquo is as white wine
One of main odor type, fragrance is strong, soft sweet cold, smell coordination, entrance sweet tea, fall the features such as mouth is continuous, tail remainder is long by
Consumers' favorable comment, sales volume are in the leading position of China's Spirits market throughout the year.
Ageing is one of important production process of Luzhou-flavor liquo, and the quality and flavor and storage and aging of base liquor have close pass
System.White spirit ageing can carry out purification and aging to original plasm wine, wine body can be kept soft, sweet refreshing with impurity elimination flavouring in traditional aging process
It only, is a kind of method of common raising wine quality.
Year wine market demand increases in recent years, and product is also more and more, and quality is irregular.The white spirit ageing time
Precise Identification also lacks scientific and effective identification method, this is also exactly the Year wine market basic reason that the good and bad jumbled together.So hair
A kind of bright detection method can be detected, and the scientific and effective identification base liquor ageing time is very significant.
Summary of the invention
Disclosed by the invention is a kind of detection method in white wine base liquor ageing time.Main purpose is to invent a kind of inspection
Survey method can detecte, and the Luzhou-flavor base liquor in scientific and effective identification different ageing times.
The technical solution adopted by the present invention to solve the technical problems is：
(1) the Luzhou-flavor liquo base liquor sample in different ageing times is numbered.
(2) spectra collection is carried out to different year white wine base liquor sample with Fourier infrared spectrograph.
(3) the base liquor ageing time detection model based on infrared spectroscopy is established.
(4) Fourier infrared spectrum data are acquired to time base liquor to be measured, and the model established using step (3) is to be checked
The base liquor fraction of the year of survey is detected.
Further, step (2), step (4) (can be selected the U.S. and match silent winged Buddhist nun's high-tensile strength infrared spectroscopy using infrared spectrometer
Instrument Nicolet iS50 and decaying total reflection ATR external member) spectra collection is carried out to base liquor, acquisition wave-number range is 4000-
650cm-1, resolution ratio 4cm-1, scanning times 8-32 times (preferential selection 32 times), each equal repeated acquisition of sample three times, is put down
Equal spectrum.In experimentation, spectra collection is carried out by background of air, first uses distilled water and dehydrated alcohol when acquiring spectrum
Diamond crystal is wiped, is waited sample after drying with drop in designated position；Using distilled water and anhydrous second after acquisition
Alcohol wipes diamond crystal, and is dried, and the spectra collection work of lower a sample has been carried out.
Further, step (3) establishes white wine base liquor using partial least squares discriminant analysis using stoichiometric number software
The relational model in time and infrared spectroscopy.
Further, usable stoichiometric number software is used for quickly detecting to base liquor fraction of the year to be detected in step (4)
Sample is predicted.
Compared to the prior art, the advantage of the invention is that method is simple to operation, sample is not necessarily to without carrying out pre-treatment
Chemical reagent is added, testing cost is reduced.The Luzhou-flavor liquo base liquor ageing time is measured using middle infrared spectrum, is made
Small with sample size, sample detection speed is fast, can be with the Fast nondestructive evaluation Luzhou-flavor liquo base liquor ageing time.Established model is quasi-
True rate is high, can be used for conventional detection, it can also be used to detect whether some new aging methods can effectively change vinosity.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
The technical solution in the present invention is clearly and completely described below.
(1) the Luzhou-flavor liquo base liquor sample in different ageing times is numbered.
(2) spectra collection is carried out to different year white wine base liquor sample with Fourier infrared spectrograph.Select U.S.'s match
Silent winged Buddhist nun's high-tensile strength infrared spectrometer Nicolet iS50 and decaying total reflection ATR external member carry out spectra collection to base liquor, acquire wave
Number range is 4000-650cm-1, resolution ratio 4cm-1, scanning times selection 32 times, each equal repeated acquisition of sample three times, obtains
Averaged spectrum.In experimentation, spectra collection is carried out by background of air, first with distilled water and anhydrous second when acquiring spectrum
Alcohol wipes diamond crystal, waits sample after drying with drop in designated position；After acquisition using distilled water with it is anhydrous
Ethyl alcohol wipes diamond crystal, and is dried, and the spectra collection work of lower a sample has been carried out.
(3) infrared spectroscopy based on different year base liquor establishes detection model using offset minimum binary.Pass through cross validation
Root mean square (RMSECV) and the coefficient of determination (r2) the good detection model of screening effect.Selection cross validation root mean square (RMSECV) connects
The nearly 0 and coefficient of determination (r2) close to 1 model, detection effect is up to best.
