Technical Abstract: The electronic nose (enose) is designed to crudely mimic the human brain in that most contain sensors that non-selectively interact with odor molecules to produce some sort of signal that is then sent to a computer that uses multivariate statistics to determine patterns in the data. This pattern recognition is then used to determine that one sample is similar or different from another based on headspace volatiles. There are different types of sensors including organic polymers, metal oxides, quartz crystal microbalance and even gas-chromatography (GC) or combined with mass spectroscopy (MS) can be used in a non-selective manner using chemical mass or patterns from a short GC column) as an enose. The electronic tongue reacts similarly to non-volatile compounds in a liquid. This review will concentrate on applications for enose and etongue technology for edible products.
