Food package changes colour from purple to yellow-green when meat spoils

Researchers have developed a new food packaging technology designed to indicate meat spoilage by changing color from purple to yellow-green. The system provides a direct visual indicator to consumers regarding the freshness and safety of packaged meat products.

The development aims to reduce food waste and prevent foodborne illnesses by offering a reliable, real-time method to detect when meat is no longer safe for consumption, moving beyond traditional expiration dates.
