Types of Smart Labels
Several types of smart labels food packaging are currently available or under development, each with unique capabilities:
Time-Temperature Indicators
These labels visually indicate the cumulative temperature exposure of a food product over time. They work by undergoing a color change or other measurable alteration based on the product’s temperature history. If the food has been exposed to temperatures outside the recommended range, the indicator will change, alerting consumers or retailers to potential spoilage. The benefit lies in monitoring temperature fluctuations during transport and storage, ensuring food remains safe and of optimal quality.
Freshness Indicators
These smart labels actively monitor the freshness of food by detecting volatile organic compounds emitted by the food as it degrades. These VOCs are byproducts of microbial growth and enzymatic activity. The label changes color or provides another indication to signal that the food is no longer at its peak freshness, providing a more accurate assessment of spoilage than relying solely on expiration dates.
Radio Frequency Identification Tags
RFID tags are small, electronic devices that can be attached to smart labels food packaging and used to track products throughout the supply chain. These tags contain a unique identifier that can be read wirelessly using RFID readers. This technology enables real-time tracking of food products from farm to table, providing valuable data on location, temperature, and handling history.
Near Field Communication Tags
NFC tags are another type of wireless technology that allows consumers to access detailed product information using their smartphones. By tapping their phone on the NFC-enabled smart labels food packaging, consumers can access nutritional information, recipes, product authentication details, and more.
