Abstract Purpose -This paper aims to study different possibilities for implementing easy-to-use and cost-effective micro-systems to detect and trace expelled gases from rotten food. The paper covers various radio-frequency identification (RFID) technologies and gas sensors as the two promoting feasibilities for the tracing of packaged food. Monitoring and maintaining quality and safety of food in transport and storage from producer to consumer are the most important concerns in food industry. Many toxin gases, even in parts per billion ranges, are produced from corrupted and rotten food and can endanger the consumers' health. To overcome the issues, intelligent traceability of food products, specifically the packaged ones, in terms of temperature, humidity, atmospheric conditions, etc., has been paid attention to by many researchers. Design/methodology/approach -Food poisoning is a serious problem that affects thousands of people every year. Poisoning food must be recognized early to prevent a serious health problem. Contaminated food is usually detectable by odor. A small gas sensors and low-cost tailored to the type of food packaging and a communication device for transmitting alarm output to the consumer are key factors in achieving intelligent packaging. Findings -Conducting polymer composite, intrinsically conducting polymer and metal oxide conductivity gas sensors, metal-oxide-semiconductor field-effect transistor (MOSFET) gas sensors offer excellent discrimination and lead the way for a new generation of "smart sensors" which will mould the future commercial markets for gas sensors. Originality/value -Small size, low power consumption, short response time, wide operating temperature, high efficiency and small area are most important features of introduced system for using in package food.

“…The tailoring and designing of nanocomposites powders and thin films based on semiconducting oxide materials are important objectives for advanced industrial applications (Beltrán et al 2008;Chou and Wang 2006;Aprile et al 2008;Zakrzewska 2001;Santen and Neurock 2006). Mixed oxide compounds, such as solid solutions of ZnOSnO 2 , WO 3 -TiO 2 , SnO 2 -WO 3 and SnO 2 -TiO 2 , seem to be promising candidates for various technological applications.…”

“…Mixed oxide compounds, such as solid solutions of ZnOSnO 2 , WO 3 -TiO 2 , SnO 2 -WO 3 and SnO 2 -TiO 2 , seem to be promising candidates for various technological applications. Such complex oxide systems may benefit from the combination of the best physical and chemical properties of the pure compounds (Chou and Wang 2006;Aprile et al 2008;Zakrzewska 2001;Santen and Neurock 2006). Among all, mixed semiconducting oxide systems based on both ceramic TiO 2 and SnO 2 material with rutile structure are an attractive group of materials in terms of the electronic, optical properties, thermal and chemical stabilities (Beltrán et al 2008;Santen and Neurock 2006).…”

Ti 1-x Sn x O 2 nanoparticles have been successfully prepared by solvothermal method. Sn (II) chloride dihydrate powder and Ti (IV) chloride liquid were used as Sn and Ti precursors in HCl/HNO 3 acid mixture. SEM and EDX analyses showed that the precipitated powders are composed mainly of Ti, Sn and O elements. While the sample treated at 100°C showed high-intensity chlorine EDX peak, the one treated at 150°C did not. XRD patterns showed that precipitated powder at 150°C for different reaction time intervals (6-48 h) were in the form of rutile crystallographic structure. Calculated crystallite size (*1.30 nm) using Scherrer's formula and WilliamsonHall plot showed that the micro strain effect was very low. UV-Vis spectrometry showed that two absorption peaks could be detected at 3.86 and 3.62 eV, respectively. The obtained results can open the door toward synthesis of other nanocomposite semiconductors at low temperatures without the need of further annealing and with unique properties.
