Edible food packaging made from milk proteins

“At the grocery store, most foods—meats, breads, cheeses, snacks—come wrapped in plastic packaging. Not only does this create a lot of non-recyclable, non-biodegradable waste, but thin plastic films are not great at preventing spoilage. And some plastics are suspected of leaching potentially harmful compounds into food. To address these issues, scientists are now developing a packaging film made of milk proteins—and it is even edible. The researchers are presenting their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world’s largest scientific society, is holding the meeting here through Thursday. It features more than 9,000 presentations on a wide range of science topics.

“The protein-based films are powerful oxygen blockers that help prevent  . When used in packaging, they could prevent food waste during distribution along the food chain,” says research leader Peggy Tomasula, D.Sc.

And spoiled food is just one issue. Current food packaging is mainly petroleum-based, which is not sustainable. It also does not degrade, creating tons of plastic waste that sits in landfills for years.”
