Abstract

The invention provides a fluorescence spectrum method for discerning Yanghe blue classic series liquor. The prior art has no convenient and sensitive method for detecting Yanghe blue classic series liquor. Therefore, taking low-priced hedge liquor for premium liquor is appeared on the market to imitate high-grade liquor. The invention discerns Yanghe blue classic series liquor through optical spectrum. When discerning, firstly, the detected fluorescence spectrum data of a plurality of Yanghe blue classic series liquors are stored, and a spectrum databank is formed. Then, the corresponding fluorescence spectrum data of the liquor to be discerned is detected. Finally, the brand of the Yanghe blue classic series liquors to be detected is determined through comparing the spectrum signature data. By adopting the method of the invention, the discerning of Yanghe blue classic series liquor can be convenient and effective.

Description

A method for identifying Yanghe blue classic liquor by fluorescence spectrum

technical field

The invention relates to the identification of Yanghe blue classic liquor, in particular to a method for identifying Yanghe blue classic liquor through fluorescence spectrum.

Background technique

The product quality of Yanghe Blue Classic Liquor is well-known both at home and abroad for its excellent wine quality and mellow aroma. It is a cultural food of the Chinese nation. However, because the ingredients in the wine system are too complicated, the quality of the wine is still identified through human senses. Identification is time-consuming, laborious and inefficient.

Contents of the invention

The object of the present invention is to provide a method for identifying Yanghe blue classic liquor through fluorescence spectrum, through which method can conveniently and sensitively identify Yanghe blue classic liquor.

According to the technical scheme provided by the present invention, the method for identifying liquor by fluorescence spectrum includes the following steps: (1) preparing a spectral database storing the spectral data of the standard Yanghe blue classic series liquor; (3) extract the brand information of the Yanghe blue classic series liquor that is the same as the spectral data of the liquor to be identified in the spectral database; (4) output the brand information of the Yanghe blue classic liquor.

Yanghe blue classic series liquor includes three kinds of liquors: sea blue, sky blue and dream blue. The spectral data of Yanghe blue classic series liquor is the characteristic data of fluorescence spectrum peak wavelength and spectral line shape. The fluorescence spectrum of Yanghe blue classic series liquor was measured by a multifunctional fluorescence measurement system. In step (1), the Yanghe blue classic series liquor includes standard Yanghe blue classic series liquor of different brands. In step (1), preparing the database includes: storing the measured spectral data of the standard Yanghe blue classic series liquor to form a spectral database, or obtaining a spectral database storing the spectral data of the standard Yanghe blue classic series liquor.

In step (2), the spectral data of the liquor to be identified includes characteristic data of fluorescence spectrum and spectral line type. Fluorescence spectra were measured by a multifunctional fluorescence measurement system.

In step (3), extract the spectral data in the database that is the same as the spectral data and fluorescence spectral line type of the liquor to be identified, and then select the brand information of the Yanghe blue classic series liquor corresponding to the spectral data .

Compared with the prior art, the method of the present invention to identify the classic series of Yanghe blue liquors by fluorescence spectrum first stores the spectral data of each standard liquor to make a spectral database, then measures the spectral data of the liquor to be identified, and then extracts the For the Yanghe blue classic series liquor corresponding to the same spectral data as the liquor to be identified in the database, finally output the name of the Yanghe blue classic series liquor, so that the Yanghe blue classic series can be easily and effectively identified A series of liquor brands.

Detailed ways

Embodiment one

Referring to FIG. 1 , step S10 is firstly carried out, storing the measured fluorescent spectrum library of each standard Yanghe blue classic series liquor and making the spectral line shape feature data into a spectral database. In this example, the ocean blue, sky blue and dream blue of the Yanghe wine series are taken as examples to illustrate. The corresponding wavelengths are 307.67, 284.04 and 279.04 nm, respectively. You can also purchase CD-ROMs from institutions that store such information in order to obtain related information.

Then continue to step S11, measure the fluorescence spectrum of the Yanghe blue classic series liquor to be identified and obtain the characteristic data of the peak wavelength of the fluorescence spectrum and the spectral line shape. In this embodiment, the liquor to be identified is Dream Blue, and the fluorescence spectrum of the liquor to be identified is measured under the excitation of 210nm ultraviolet light by the multifunctional fluorescence measurement system of the model SP-2558 produced in the United States to obtain its fluorescence spectrum The peak wavelength is 279.04nm.

Then continue to step S12, extract the spectral data in the spectral database that is the same as the spectral data and fluorescence spectral line type of the liquor to be identified, and then select the type information of the Yanghe blue classic series liquor corresponding to the spectral data. In this embodiment, the extracted liquor is Dream Blue.

Then continue to step S13 to output the name of the Yanghe blue classic series liquor. In this embodiment, the liquor is output as Dream Blue to a display unit such as a monitor or a voice prompt unit such as a speaker.

To sum up, the method of the present invention for identifying Yanghe blue classic series liquors by fluorescence spectrum first stores the spectral data of each standard Yanghe blue classic series liquors to form a spectral database, and then measures the corresponding spectra of the liquors to be identified. Data, then extract the type information of Yanghe blue classic series liquor in the spectral database that is the same as the spectral data of the liquor to be identified, and finally output the type information of the liquor, so that Yanghe blue can be easily and sensitively identified Types of Classic Color Liquor.
