New technology developed by Brazilian researchers can transform the way food quality is monitored . It is a intelligent packaging capable of change color as deteriorated A, visually signaling if it is suitable for consumption.
Innovation was created by scientists from Embrapa Instrumentation (SP), in partnership with Embrapa Food Agroindustry (RJ) and the University of Illinois, in Chicago (UIC), in the United States. The system uses natural pigments extracted from the purple cabbage and applies a technique called wind wiring In solution to produce nanofiber blankets – these react to compounds released during food decomposition.
In laboratory tests, the smart blankets were Used to pack Fish Fish Merluza. With the packaging closed throughout the process, initially, the package presented purple color, indicating that the fish was fresh. After 24 hours, the color began to fade. Within 48 hours, blue tones emerged, and at the end of 72 hours, the blue tone confirmed the deterioration of the food.
According to the researchers, the material behaves as a visual sensor and can function as a Effective indicator of the quality of fish and seafood. However, they warn that more studies are needed to verify their effectiveness with different food species.
In the future, technology is expected to be applied on a large scale in the food industry, helping to reduce waste and increase consumer safety.
