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.
