Instant enumeration of total viable bacterial counts for food quality assurance using 'DEP-On-Go' sensor

Food quality has to be constantly monitored from farm-to-table to control foodborne illness. Total viable count (TVC), which estimates the population of live microbial load, can be an extremely useful tool for food quality assurance. This work presents the utility of an electrochemical 'DEP-On-...

Description
Summary:Food quality has to be constantly monitored from farm-to-table to control foodborne illness. Total viable count (TVC), which estimates the population of live microbial load, can be an extremely useful tool for food quality assurance. This work presents the utility of an electrochemical 'DEP-On-Go' sensor to determine TVCs instantly and quantitatively in milk and other food samples, including vegetables, and meat, using the oxygen consumption activity of viable microbes. We present the analytical performance of our device for the sensitive detection of the TVC in packed milk with a detection limit of ≤300 CFU mL −1 , which fulfills the acceptable limit (
