“Milk, Not Plastic, Will Protect Food in the Future”

U.S. Department of Agriculture researchers have discovered that a milk protein called casein can be used to develop an edible, biodegradable packaging film. The casein-based film is up to 500 times better than plastic at keeping oxygen away from food because proteins form a tighter network when they polymerize, the researchers found. It’s also more effective than current edible packaging materials made from starch and protects food products that are sensitive to light.
