Researchers Say Photocatalysis Is Most Effective Technology For Keeping Fruits, Veggies Fresh

May 15, 2013: 12:00 AM EST
French researchers have determined that a technology known as photocatalysis has the greatest potential for removing spoilage-inducing ethylene gas – produced by fruits, vegetables and flowers – from shipping and storage containers. The gas normally speeds the ripening process, but also causes unwanted ripening, spoilage and financial losses. The researchers reviewed 300 published studies and compared all existing ethylene control/removal methods and technologies. The sustainable technology photocatalysis combines a catalyst and light to transform ethylene gas into carbon dioxide and water.
