Food Packaging You Can Eat
Plastic wrap—so much of our food comes in it, from meats and cheeses, to breads and snacks. Not only is it non-recyclable and non-biodegradable—accumulating in landfills everywhere—it also doesn’t stop food from spoiling very well. Then, there are the questions and concerns about potentially toxic substances from the plastics leeching into the food. Soon, there may be a better option.
Researchers at the U.S. Department of Agriculture are developing a new food packaging material made from milk proteins that will keep food fresher, is environmentally-friendly, and even can be eaten. Because it is not petroleum-based—like most plastics—it is also more sustainable than plastic packaging.
The substance is less stretchy than plastic wrap, and protects food better than other edible packaging products already on the market, which are made from starch. According to researchers, flavorings and nutrients could be added in the future.
