Embodiment 1

[0088] Example 1: Identification of Fen-flavor Brewed Liquor and Liquor Clear Blended Liquor

[0089] (1) Establish fingerprints of brewed liquor and alcohol blended liquor

[0090] a. Preparation of test samples.

[0091] According to the national standards for blending liquor, an enterprise is entrusted to prepare alcohol-blended liquor and provide brewed liquor, including 10 samples of brewed liquor and 7 samples of alcohol-blended liquor.

[0092] b. Carry out coulometric array high performance liquid chromatography detection on the test sample.

[0093] Instrument: Model 5600A produced by ESA Company in the United States, equipped with a high performance liquid chromatograph (HPLC-ECD) with a Coulomb array electrochemical detector.

[0094] Methanol and acetonitrile are chromatographically pure, sodium dihydrogen phosphate is analytically pure, and water is distilled water.

[0095] Chromatographic conditions: Phase A in the mobile phase is: 30mmol aqueous solution of ...

Embodiment 2

[0122] Example 2: Classify and identify liquors with different blending ratios

[0123] Four different proportions of brewed liquor (100%, 75%, 15% and 10%) were selected for high-performance liquid chromatography analysis, and the analysis method was the same as in Example 1. The liquid chromatograms of four kinds of liquor brewed in different proportions are shown in Figure 17 to Figure 20. From each figure, it can be clearly distinguished the liquor with a concentration below 15% and above 75%, while 10% and 15%, 75% and There is not much difference in the spectra between 100%, and because there are many peaks, it is difficult to visually select substances for comparison. A large amount of data in the spectrogram was further statistically analyzed using the Pirouette data processing software using the fingerprint model established above, and the data map is shown in Figure 21.

[0124] Cluster analysis was performed on four liquor samples with different concentrations, amo...

Abstract

An identification method of the brewing distilled spirit and the matching distilled spirit by alcohol includes the below processes: (1) setting the brewing and matching distilled spirit fingerprint chart by the coulomb array HPLC and getting the fingerprint chart data; (2) setting the fingerprint chart static module; (3) analysis of the detecting distilled spirit sample by the above method and getting the coulomb array HPLC data to identify by the fingerprint chart module. The invention is to analyze the distilled spirit quality by the HPLC-ECD and set the fingerprint module using the multivariate statistical software, also it can distinguish the original drink with different concentration and quality and has high sensitivity and visual result. So the method of invention can set the fingerprint chart module of different kind drink to form the fingerprint chart bank.

Description

technical field [0001] The invention relates to a method for identifying brewed liquor and alcohol-blended liquor, in particular to a method for identifying brewed liquor and alcohol-blended liquor by using liquid chromatography equipped with a storage array electrochemical detector and multivariate statistical software. Background technique [0002] As a traditional industry of the Chinese nation, the liquor industry has gone through thousands of years of development and is a wonderful flower in the world of distilled wine. Although there are still inconclusive opinions about the origin of liquor, its rich cultural heritage accumulated over thousands of years is unmatched by other industries. With the advancement of science and technology and the improvement of people's material and cultural living standards, drinking liquor has gradually shifted from a pure physical hobby in the past to a spiritual taste of liquor culture, personality and fashion. Liquor, as a traditional...
