We will soon be able to say goodbye to the packs of #plastic for foods, which will be replaced by edible and biodegradable films produced from milk. This emerges from research by the United States Department of Agriculture presented at the meeting of the American Chemical Society in Philadelphia. Within three years the first "milk" packaging should be ready.
“The film produced with milk proteins is a lot effective in blocking oxygen, ensuring better preservation of food in the distribution chain and consequently reducing waste,” said Peggy Tomasula, coordinator of the study. This packaging, therefore, is not only ecological and biodegradable, but also more effective than plastic in preserving food.
Until now, biodegradable packaging on the market was made from potato starch. But they are more porous and allow more oxygen to penetrate, resulting in poor preservation results. The new film, however, will be more effective. Furthermore, milk-derived plastic can be applied as a spray on foods less resistant to contact with humidity, such as cereals, or to ideally preserve pizza.
