Much of the plastic packaging we see in*the grocery store can be recycled, from egg containers, to milk jugs, to butter tubs. But what about that thin plastic film stretched around*wedges of manchego in the cheese bin or the 16-ounce rib-eye in the chiller case?
It turns out that kind of plastic*is*tougher to recycle (http://info.goodstartpackaging.com/blog/three-reasons-why-disposable-plastic-is-unsustainable)*and might even be adding harmful chemicals (http://www.webmd.com/food-recipes/features/cookware-plastics-shoppers-guide-to-food-safety#1)*to your food. Oh, and it’s***t even good at doing what*it’s supposed to do:*prevent*food spoilage.*
Luckily, researchers (http://www.bloomberg.com/news/articles/2013-02-28/david-edwardss-wikicell-makes-edible-food-packaging)*are investigating alternative forms of food packaging—the kind you can eat.
U.S. Department of Agriculture researchers*have discovered that*a*milk protein called casein can be used (https://www.youtube.com/watch?v=wt32GgQGTcI&feature=youtu.be) 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.* Read more...
