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 a research by the United States Department of Agriculture presented at the congress of the American Society of Chemistry, in Philadelphia. Within three years, the first "milk" packaging should be ready ..
“The film made from 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. Therefore, these packaging are not only ecological and biodegradable, but also more effective than plastic in the preservation of food.
Until now, biodegradable packaging on the market was built from potato starch. But they are more porous and let in more oxygen, with poor storage results. The new film, however, will be more effective. Furthermore, the plastic derived from milk can be applied as a spray on foods that are less resistant to contact with humidity, such as cereals, or to ideally preserve pizza.
