Most foods at the grocery “meats, breads, cheeses, snacks” store 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. Scientists are now developing a packaging film made of milk proteins – and it is even edible.
Its a new form of packaging, made from: milk. Yes, the very same milk you use daily. More specifically, a milk protein called casein is the driver, which could be used in the future to develop a form of edible packaging that’s 500 times better at keeping food fresh than plastic.
In addition to casein, researchers tested adding glycerol and citrus pectin to the already-formed casein film, which added both structure and softness.
Additives and flavors been added enhance the food contained within, or to improve the taste of the new “plastic.”
Essentially, packaging created from casein could be immersed in boiling water to form your delicious bowl of chicken noodle soup, or eliminate the need to peel the wrappers from foods entirely. Just throw the whole thing on a sandwich!
Unfortunately, the packaging isn’t quite ready for distribution, as the USDA is still hard at work bringing it into execution. It could happen in the future, however, the real question is, what would it taste like?
