In recent years, demand for electronic nose systems has increased and has taken its place among the fast techniques due to increasing interest in the studies for developing fast and economic techniques in determining the quality properties of foods. Electronic nose systems that mimic the human olfactory mechanism have gas sensors designed for different technologies in different types. Metal oxide semiconductor gas sensors (MOS) based on conductivity measurement from these gas sensors has found wide usage in medicine, chemistry, agriculture, and food sector due to its rapid response, cheapness, robustness, and portability. Food quality, shelf life, storage, microbial contamination, degradation, adulteration, and classification are among the studies carried out by means of electronic nose technology. The use of electronic nose metal oxide semiconductor gas sensors can be an alternative to existing food analyses and provide an opportunity to verify their results. In this review, it is aimed to summarize electronic nose metal oxide semiconductor sensors and especially scientific studies carried out by these sensors in food analyses.
