The inability to monitor real-time milk freshness leads to food waste, health risks, and reduced consumer trust. Best-before dates are often inaccurate. To solve this, FRESHTAG uses food-grade electrodes to measure milk impedance and temperature, detecting spoilage changes. A Bluetooth reader sends data to a mobile app, showing “Safe,” “Caution,” or “Not Safe.” This smart, real-time system improves food safety, reduces waste, and supports sustainable consumption.
