Russian scientists have created a method of Express-analysis, which allows for a minute to determine the presence of synthetic dyes in juices and wines. About it RIA Novosti was told in the all-Russian scientific research Institute of physical-technical and Radiotechnical measurements.
Researchers have created a device that, using this method, in real-time detects the presence of synthetic dyes in the analyzed sample. The analysis process takes less than a minute, said the representatives of the scientists. The device is called “photospectrometry analyzer synthetic dyes”.
“The most promising was the direction associated with the use of spectrophotometry. (…) Determined the dependence of the absorption spectrum of electromagnetic radiation from the availability of synthetic dyes in colored transparent juices and wines” — explained the expert.
It is noted that the question of the method of determining the fake wine experts after treatment from the Institute of beverage and wine industries.
In October it was reported that Russian wine is conceived in a special way to highlight on restaurant menus. It was proposed to put the Russian drinks the wine lists are higher than foreign, or to use a custom font.
