«Electronic tongue» is being tested in the Moscow State University
Scientists from the Moscow State University (MSU) and the University of Valladolid (Spain) have created and conducts testing of thin-film sensors to assess the quality of wines. Sensors may also be used to determine the authenticity and age of wines.
«Electronic tongue» can recognize the type of wine in accordance with the index of polyphenols. The content of polyphenols depends of variety, climatic conditions and the degree of ripeness. During the tests sensors distinguished three samples of wines, which are made from one kind of grape. High sensitivity was achieved by adding to the sensors special organic compounds — subphthalocyanines.
«Having a wine database, one can determine their quality, age, grape variety and detect a forgery. In the future, we plan to expand the range of subphthalocyanines used in sensors, and to improve the thin film applying technique», Tatiana Dubinina, researcher of the Faculty of Chemistry, told.
The results are published in Electrochimica Acta.
