The Application of Gas Sensor Array based Electronic Nose for Milk Spoilage Detection
Microbial spoilage in milk is a crucial concern for healthy consumption. This study aims to apply the electronic nose system (e-nose) comprising an array of different gas sensors as an initial tool for monitoring of food spoilage for maintaining food safety and human health. In this system, nanocomp...

Microbial spoilage in milk is a crucial concern for healthy consumption. This study aims to apply the electronic nose system (e-nose) comprising an array of different gas sensors as an initial tool for monitoring of food spoilage for maintaining food safety and human health. In this system, nanocomposite gas sensors based on different polymers and functionalized single-walled carbon nanotubes (f-SWCNTs) are employed. By exposure of these gas sensors to the milk's headspace, the gas sensors show responsive signals toward volatile organic compounds (VOCs) contained in the milk.
