Abstract: The electronic nose emerged in the mid 80's due that the food industry needed quicker instruments to be applied in food control for the characterization of smell, in order to complement the work done by human panels. But scientific researchers noticed that electronic nose could also be used in other fields, such as environmental contamination, health, defence, automotive industry, control of hazardous substances, etc. The aim of this research article is to explain how electronic nose work and to report the latest researches obtained with electronic nose in the Centre of Investigation of Solids (CINSO).


Keywords: Electronic nose, MOX sensors, QMB sensors, extra-virgin olive oil, garlic, tomato, volatile compounds
