A single drop may be enough to check wine for alcohol, sugars, and other substances. MSU scientists have developed an artificial intelligence system that analyzes the chemical composition of a drink in less than a minute after measuring its spectrum. The method was tested on 1734 samples, including real white and red wines. Sergey Dolenko, head of the laboratory of adaptive data processing methods at the Nuclear Physics Research Institute of MSU, spoke about the development.

According to the researchers, less than 50 microliters of wine are required for analysis. The system determines the content of five components — ethanol, sugars, acids, glycerol, and sulfur dioxide. The latter is used in winemaking, in particular, to protect the drink from undesirable changes during storage.

For verification, the scientists used infrared spectroscopy. The device records how molecules of substances interact with infrared radiation. The resulting spectrum contains characteristic features of different components, and a machine learning algorithm helps to recognize them and estimate the quantity.

Researchers believe that this approach can reduce the cost of software for express wine analysis devices. In the future, it is also proposed to adapt it for checking juices and carbonated drinks.

The results of the work are published in the scientific journal Scientific Reports. However, even if modern technologies allow for quick and accurate determination of the chemical composition of wine, this does not make alcohol safe for health.

Alcohol consumption increases the risk of developing a number of diseases, and regular consumption can lead to addiction. Alcohol is harmful to health.
