Intelligent Labeling and Sensors
Intelligent packaging and use of sensors have great potential for reducing food waste and thereby improving food security. There are four families of sensors—for freshness, food package integrity usually gas sensors, time-temperature indicators (TTI), and identification tags such as radio-frequency identification (RFID).
- The TTIs' are helpful for detecting temperature abuse along the distribution chain, and could permit dynamic dating of a foodstuff's shelf life. One could foresee replacing the “use by dates” by e.g., a TTI indicator turning red if the foodstuff is not suitable for human consumption or yellow if the food quality declines.
- The RFID tags are helpful for tracing and tracking a food product as it provides real time information on the food product identity and the food chain. Moreover, the RFID tags could provide data for analyzing the causes of food waste and losses.
