This fresh food packaging changes color to indicate the freshness of its contents. Developed by Brazilian petrochemical company Braskem, the packaging can measure pH indicators and other factors of food spoilage. This allows the food containers to change color according to the health of the food inside, and make it more clear to consumers. However, according to Springwise, the sensor cost is not currently commercially viable to bring the product to a mass market.
The fresh food packaging addresses food waste, and especially food that gets thrown away because of label confusion. Often consumers will get rid of food simply because 'use by' and 'best before' dates are not made clear. Other packaging solutions designed to reduce food waste include biodegradable food containers.
