Spanish researchers develop portable ‘electronic nose’

Spanish researchers have developed a cheap, portable ‘electronic nose’ they say has great promise for use in organoleptic testing and food quality control. While so-called e-noses themselves are not new, the University of Extremadura Sensory Systems Research Group says its system reduces the time and cost of testing. In a recent press release, researcher Jesus Lozano said that the new system – which mimics the human nose – could not only deliver quantitative results in a minute, it cost ten times less than existing methods to set up.
