Detection equipment + new technology to identify fake wine without opening the bottle

[ Focus on Chemical Machinery and Equipment Network ] As an ancient beverage, wine has almost run through the history of mankind.
From myths and legends to real history, wine has always been an important part of human society.
Today, even though the development of the food industry has given modern people an extremely rich variety of beverages to choose from, the status of wine has never been shaken.
In the alcohol market, whiskey is highly sought after as a representative of spirits, just like the status of liquor in my country.
The counterfeiting of whiskey is the same as our country's liquor, especially the finest Scotch whisky.

 

Rare whisky with a long vintage is not weaker than wine in the collector's market.
However, the fraud of these whiskeys is more serious than that of wine.
A 2018 study randomly selected 55 bottles of whiskey with high collectible value and carried out radiocarbon dating on them, and found that 21 of them were fraudulent.
This has forced market research to identify methods for authenticating whiskey.

 

Wine identification methods are relatively mature, especially wine identification, and even the time and place of production of samples can be traced back.
This provides a great reference for the identification of whiskey.
The main raw materials of whiskey are water and barley malt or grains (wheat, rye and corn).
Although the raw materials are relatively simple, the composition is very complex.
In addition, during the aging process, the interaction between the barrel and the whiskey will also change the liquor.
The chemical composition and flavor.
Therefore, in theory, only need to check the chemical composition of a bottle of wine in detail to determine whether the bottle of wine matches the description of the merchant.
This method mainly uses gas chromatography-mass spectrometry and gas chromatography-olfactory method.
Identify the key aromatic active ingredients in the wine through analytical instruments and construct the "chemical fingerprint" of each whiskey.

 

　　In addition, some researchers started from the electronic tongue and developed an "artificial tongue" that can taste the true and false whiskey.
This artificial tongue is composed of chemically modified nano-metal made of gold and aluminum.
Although it cannot distinguish the chemical composition of the whiskey liquor, different types and years of whiskey will cause different changes in the metal plasma resonance.
, To determine the authenticity of whiskey.

 

　　With the advancement of technology, scientists have been able to identify whiskey more and more accurately and conveniently.
However, there is a problem with the above-mentioned methods, that is, the bottle must be opened for sampling to analyze the bottle's liquor.
This will damage the value of a bottle of whiskey to a certain extent.
How to non-destructively test the chemical composition of a bottle of whiskey? The researcher chose the spectrum.
Only need to illuminate the light source and analyze the spectrum of the wine bottle to get the composition information.
But the wine bottle will also produce a large number of spectral signals, which will interfere with the spectrum of the wine.
Therefore, unless the problem of the spectral signal of the wine bottle is solved, the spectroscopy method also needs to open the bottle to sample.

 

　　Recently, researchers finally solved this problem.
They let the laser as the light source emit a ring instead of the normal focused beam to suppress the noise signal of the glass bottle.
Then using a conical lens, the laser can be refocused into the whisky liquor after passing through the glass bottle to obtain the spectral information of the liquor.
The goal of identifying the authenticity of whiskey without opening the bottle is achieved, and it can also be applied to other spirits such as vodka.

 

　　It is believed that the development of detection technology will bring about major changes to the wine market, and both producers and distributors of real wine and consumers will benefit from it.
Not only whiskey, but not only the alcohol market, the advancement of food testing technology has a similar meaning to the food industry.
This is also a manifestation of the impact of detection technology on production and human life.
