In sum, sensor panels are an essential aspect in the industrial
food processes, but the difficulty and cost to maintain such panels
is high. Consequently, for day-to-day production having a tool such
as an electronic nose which would in effect be synchronized with
an eventual panel would be valuable for industrial use. The use
of an electronic nose to complement human panels particularly if
‘‘non-odorant’’ gases are to be detected is promising. Nevertheless
the general practice is to use the sensor panel to define the targets
for quality detection and train the nose on these descriptors. In
order for a symbiosis between electronic noses and human panels
to emerge in the industry, a high reproducibility remains to be
demonstrated in the electronic counterpart.
