In order to reduce food waste and meet the needs of the
demanding modern consumer regarding the quality of food
items, it is crucial to monitor the supply chain and
storage conditions of perishable food products.
Considering this scenario, temperature plays an important
role on food safety and quality during storage and
supply. In this work, a critical temperature indicator
(CTI) based on a solvent melting point is developed.
Furthermore, the present CTI working principle is
improved by the use of microfluidics technology. As final
result, a novel and functional CTI-smart sensor which
combines irreversible visual color changes and radio
frequency identification (RFID) technologies is achieved.
Such CTI integrated to a RFID tag provides a unique
advantage to monitor the supply chain in real time by the
simple use of a RFID reader in strategic points.
