JAOCS article of the month: E-tongue discrimination of monovarietal olive oils
“Simple and cost-effective techniques for evaluating physicochemical and sensory attributes of olive oil for traceability, authenticity, adulteration and legal purposes are needed,” says Journal of the American Oil Chemists' Society (JAOCS) Editor-in-Chief James Kenar. In Kenar’s choice for JAOCS article of the month, António M. Peres at the Instituto Politécnico de Bragnaça, in Portugal, and colleagues have coupled a potentiometric electronic tongue with chemometric analyses to discriminate the geographical origin, olive cultivar and quality grade of monovarietal Tunisian olive oils from nearby regions experiencing similar climatic and agroecological factors. The results show good sensitivity and demonstrate this technology as a possible strategy for olive oil analysis. The article is available for free download through April 20.
