Steven Britz from the US Department of Agriculture’s Food Components and Health Laboratory has created a UV-lit refrigerator that improves the life expectancy of foods. The prototype has even kept strawberries fresh for up to nine days, with no signs of mold or rot.

The low irradiance UV-LED lights that Britz used work well in cold conditions and are less hazardous than traditional UV bulbs and also need little power to run.

The refrigerator more than doubles food’s storage life and even maintains colour and health benefits while reducing waste in the long run.

Britz aims to commercialise the technology to bring the refrigerator into households around the world.
