Problems solved by technology

However, judging the age of wine by color can only get a very broad area, and cannot be accurately judged
Chinese invention patent 200710202370.3 is based on the theory that the smaller the volatilization coefficient of organic components in vintage wine, the longer the storage time of vintage wine and accurately determines the age of liquor through the "Volatilization Coefficient Judgment Method", but it is not suitable for wine vintage identification; The scientific and effective identification method of vintage wine is still in the experimental stage. Although the new Chinese standard clearly defines the vintage of wine, it does not specify the exact detection standard, which will inevitably make inspection and identification difficult. Therefore, it is necessary to establish a vintage wine Identification methods are imminent
At present, there is no report on the method and device of wine vintage identification in the market and patent literature search

Embodiment 1

[0041] Select bottled vintage Cabernet Sauvignon dry red wine produced by a winery in Yunnan (1998, 2000, 2002, 2004, 2006, 2007, 2008, 2009 and 2010, bottled with a composite cork, with an alcohol content of 11-12% (v / v), the sugar content is 2.0-4.0g / L, the pH and ORP values ​​detected by the electrode are transmitted to the computer by the parameter analyzer, and then processed by the computer calculation function RH=ORP / 28.5+2pH to obtain the degree of oxidation RH ; Open the oxygen bottle to saturate the oxygen content in the wine sample, then open the magnetic stirring and heating device (model is DF-101B Collector Magnetic Stirrer ), so that the temperature of the product in the container 5 is raised according to the program of 1°C / min, the temperature is raised from 25°C to 60°C, and a set of temperature is measured every 5°C, and the oxidation-reduction potential ORP and the temperature change are detected by the electrodes. The data is transmitted to the computer 1 ...

[0043] Select bottled vintage Chardonnay dry white wine produced by a winery in Yunnan (2002, 2004, 2005, 2006, 2007, 2008, 2009 and 2010, bottled with a composite oak stopper, with an alcohol content of 11-12% (v / v), the sugar content is 2.0-4.0g / L), the pH and ORP values ​​detected by the electrode are transmitted to the computer by the parameter analyzer, and then the oxidation degree RH is obtained by the computer operation function RH=ORP / 28.5+2pH; open The oxygen bottle saturates the oxygen content in the wine sample, and then the magnetic stirring and heating device is turned on, so that the temperature in the wine is heated up in stages, from 25°C to 60°C, and the ORP and temperature changes are detected by the electrodes. The parameter analyzer is transmitted to the computer 1 through the RS232 or USB interface, and the computer 1 processes the ORP and temperature change values ​​to obtain the △ORP / △T change value. Using MatLab software to establish the first-order d...

Abstract

The invention discloses a method and a device for detecting the ageing time of dry wine. In the device, a wine accommodating container is arranged on a heating device; a container inlet is formed on the top of the wine accommodating container; an outlet is formed at the bottom of the wine accommodating container; a stirrer is arranged at the bottom of the cavity of the wine accommodating container; an electrode and a diffuser are arranged in the cavity of the wine accommodating container; the electrode is connected with a computer through a parameter analyzer and is fixed through a support; the diffuser is communicated with an oxygen bottle; and a relief valve and a flow meter are arranged on a pipeline for communicating the diffuser and the oxygen bottle. In the method, data detected by the electrode is transmitted to the computer and processed to obtain a corresponding year predicting and correcting regression model, and based on the year predicting and correcting regression model, the realness or fakeness and the year of the same variety of dry wine with the same brand can be judged. By the method and the device, the ageing time of the dry wine can be determined accurately and quickly.

Description

technical field [0001] The invention relates to the detection of aging time of dry wine, in particular to a method and device for detecting the aging time of dry wine fermented with whole juice, which is used for quickly identifying the true and false years of dry wine. Background technique [0002] Wine merchants often play the vintage card, and it is not uncommon for wine vintages to be disordered or even falsely reported. From January 1, 2008, the revised new national standard for wine, namely "Wine" (GB15037-2006), was implemented in the production field, and the recommended national standard was changed to a mandatory national standard. This standard gives a clear definition of vintage wine: the year marked must be the year when the grapes were picked, and the proportion of vintage wine should not be less than 80% of the wine content. For a long time, the vintage evaluation in the wine industry has been mainly carried out in the mode of combining professional sensory e...
