An electronic nose, comprising nine metal oxide sensors, has been built aiming to classify olive oils according the fruity intensity commercial grade (ripely or light, medium and intense greenly fruity), following European regulated complementary terminology. The lab-made sensor device was capable differentiate standard aqueous solutions (acetic acid, cis-3-hexenyl, cis-3-hexen-1-ol, hexanal, 1...
