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.

An overview of smart packaging technologies for monitoring safety and quality of meat and meat products

“…These systems are developed to test package integrity, which are essential prerequisites to uphold the quality and safety standards of poultry and meat product packaging. The reason behind the integrity damage in flexible plastic packages is linked with leaking seals . The attachment of a leak sensor or indicator to a package aids in maintaining the integrity of the package throughout the production, transportation, and distribution chain.…”

“…The attachment of a leak sensor or indicator to a package aids in maintaining the integrity of the package throughout the production, transportation, and distribution chain. Several researchers have worked on package integrity of MAP products and established critical leak size and related quality factors …”

“…The reason behind the integrity damage in flexible plastic packages is linked with leaking seals. 14,15,79 The attachment of a leak sensor or indicator to a package aids in maintaining the integrity of the package throughout the production, transportation, and distri- could also indicate leakage. As the protective atmosphere is lost due to a leak in the package, subsequently deterioration of products occurs due to microbial spoilage.…”

Synthesis and Inkjet Printing of SnO2 Ink on a Flexible Substrate for Gas Sensor Application

“…Particularly, the manufacture of flexible gas sensors based on metal oxide thin film seems to be special and presents an interesting perspective for the progress in many fields especially the smart food packaging [2,3]. However, it is subject to restrictions as it requires high operating temperature which is not compatible with plastic foils.…”
