Semi-passive RFID and beyond: steps towards automated quality tracing in the food chain

Abstract

Precise temperature monitoring is the major precondition to supervise quality losses within the transport chain for fresh products. Different types of miniaturised data loggers with electrical and semi-passive RFID interface were compared and applied to record spatial temperature profiles for typical transport situations. The resulting effects of the found temperature variations were evaluated by mathematical shelf-life modelling. Wireless sensor networks with active communication offer permanent access to sensor condition but entail higher system costs. Different approaches for implementation of integrated quality assessment will be discussed using a concept for shelf-life calculation on RFID-level and the intelligent container as demonstrator for an automated transport supervision system.

RFID smart tag for traceability and cold chain monitoring of foods: Demonstration in an intercontinental fresh fish logistic chain

“…Recently, several solutions for implementing temperature managed traceability systems using RFID tags with embedded temperature sensors have been reported (Ogasawara and Yamasaki, 2006;Jedermann and Lang, 2007). Moreover, one of the current challenges in smart tags is the integration of chemical sensors onboard of flexible tags (Abad et al, 2007a) to monitor for example the ripening or deterioration gases generated by food products.…”

EPCIS based online temperature monitoring and traceability in a cold meat chain

“…The most common solution is to use conventional paper labels for traceability information with a strip chart recorder placed inside two or three marked boxes per shipment to monitor the temperature ⁄⁄⁄⁄(Abad et al, 2009). More recently, several solutions for monitoring temperature based on traceability systems using RFID tags with integrated temperature sensors have been developed (Ogasawara and Yamasaki, 2006;Jedermann and Lang, 2007;Thakur et al, 2011). However, the information from such RFID tags with temperature sensors cannot be retrieved in real-time while the food product is in transit.…”

RFID Based Warehouse Management of Perishable Products

“…Implementation of RFID is subjected to risks and needs to follow certain protocols, rules and regulations [35,36]. Work carried out by Flores, Tanner and Amos [37] and Jedermann and Lang [38] adds value to the importance of RFID which can be effectively used in cold chains to increase self life of product and hence maintain quality for long time. Next section describes the difficulties/challenges faced by the perishable product supply chains.…”
