Look at the results

Main application areas of ELECTRONIC TONGUE

Food analysis Analysis of liquid food, beverages and brews, analysis of homogenates (flesh food, fruits, vegetables), analysis of vegetable and olive oils. Raw materials, intermediates, final products, taste substances, food additives.
Recognition, identification, classification and quality control. Multicomponent quantitative determination of the content of inorganic and organic nutrients.
Correlation between ELECTRONIC TONGUE and human sensory perception in food flavor evaluation. Basic tastes (salty, sweet, bitter, sour, umami). Prediction of human taste panel scores.
Clinical analysis Recognition and multicomponent quantitative analysis of inorganic and organic substances in biological and medical liquids. Diagnostic of diseases through the integral chemical analysis of liquid media.
Environmental analysis Analysis of pollutants in the ground water
