Technical Abstract: The electronic nose (e-nose) was used to distinguish differences between mango fruit of different harvest maturities, apple fruit to which different coatings were applied, cut apple subjected to heat and ethanol treatments as well as strawberries of different ripeness stages, based on their volatile compositions. The electronic tongue (e-tongue) was used to separate orange juice from healthy or diseased fruit (from trees affected by Huanglongbing disease). Both e-nose and e-tongue data correlated to sensory and/or chemical analyses of aroma volatiles.
