What's Happening?
Researchers have developed a biodegradable food packaging film that doubles as a sensor, using onion waste-based quantum dots to detect spoilage and contamination in real time. The film, described in Scientific Reports, combines amylopectin with sulfur and nitrogen-doped carbon quantum dots, providing a sustainable solution for food safety. The sensor visually indicates the presence of spoilage microorganisms and chemical contaminants, offering real-time insights into food quality.
Why It's Important?
The development of intelligent packaging solutions addresses global food safety challenges by providing real-time detection of spoilage and contamination. This innovation reduces reliance on slow, lab-based analysis, enhancing food safety and reducing waste. By utilizing sustainable materials, the sensor supports environmental goals, offering a cost-effective and eco-friendly approach to food packaging.
