The plastic packaging that most foods come wrapped in isn’t just a tremendous source of environmental waste. These kinds of packages aren’t even particularly adept at preventing food spoilage and they may even leech harmful chemicals into food. Now researchers are developing a biodegradable, edible film made from a milk protein called casein to hopefully solve these problems.
This film technology could have a variety of uses beyond simply reducing the amount of plastic used to contain food. They could create opportunities for single-serve portions of soup or instant coffee that could dissolve in hot water, or even help cereal stay crunchy in milk.
