Quality-Controlling Smart Labels
ZenxTag is Expanding Through 2026 Following Successful Pilot
Colin Smith — October 21, 2024
ZenxTag, a start-up developed by researchers from the City University of Hong Kong, launched smart food labels in 2025 to enhance internal quality control in the food production and distribution industries. These labels utilize chemosensitive ink that reacts with biogenic amines, a biomarker for detecting freshness in protein-rich items such as meat and seafood. The color-changing labels provide a simple and accurate method for assessing food freshness, helping to reduce food waste and improve inventory management.
The smart food labels from ZenxTag are designed to be integrated with the Internet of Things (IoT) technology, offering real-time information on food freshness and stock levels. This advanced technology supports better decision-making in food logistics and quality control, ensuring that consumers receive fresh and safe products. By providing a reliable and efficient solution for monitoring food quality, ZenxTag's smart food labels are set to revolutionize the food industry's approach to quality control and waste reduction.
