Abstract

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.

Elektronik Burun Metal Oksit Yarı İletken Sensörlerin Gıda Analizlerinde Kullanımı

Abstract

Son yıllarda gıdaların kalite özelliklerinin belirlenmesinde hızlı ve ekonomik teknikler geliştirilmesine yönelik çalışmalara artan ilgi nedeniyle, elektronik burun sistemlerine olan talep artmış ve bu sistemler hızlı teknikler arasında yerini almıştır. İnsan koku alma mekanizmasını taklit eden elektronik burun sistemlerinde farklı teknolojiler için farklı tiplerde tasarlanmış gaz sensörleri bulunmaktadır. Bu sensörlerden iletkenlik ölçümüne dayalı metal oksit yarı iletken gaz sensörleri (MOS) hızlı tepki vermesi, ucuz, sağlam ve portatif olmaları nedeniyle tıp, kimya, ziraat ile gıda sektöründe geniş kullanım alanı bulmuştur. Gıdaların kalitesi, raf ömrü, depolanması, mikrobiyal kontaminasyonu, bozulması, tağşişi ve sınıflandırılması elektronik burun teknolojisi yoluyla yürütülen çalışmalar arasındadır. Elektronik burun metal oksit yarı iletken gaz sensörleri, mevcut gıda analizlerine bir alternatif oluşturmuş ve sonuçları doğrulama olanağı sağlamıştır. Bu derlemede elektronik burun metal oksit yarı iletken sensörleri ve özellikle gıda analizlerinde bu sensörlerin yardımıyla gerçekleştirilen bilimsel çalışmaların özetlenmesi amaçlanmıştır.
