Researchers from the US Department of Agriculture (USDA) may have found a viable solution to plastic waste. They are working on an edible film that’s biodegradable and can make a great alternative to plastic wrap. The innovative film is made from citrus pectin and a milk protein called casein, which is more effective at protecting food products that are sensible to light. Flavours and vitamins can also be added to make it more nutritious.
“The coatings applications for this product are endless. We are currently testing applications such as single-serve, edible food wrappers. For instance, individually-wrapped cheese sticks use a large proportion of plastic.” Despite its potential, the discovery won’t be available shortly unless companies find a way to apply it.
