From Brazil to the World News
A new product promises to be more efficient than the plastic – and still be edible. No use crying over spilled milk – because if you take it straight, the substance can create a material that protects food and, break, relieves a little our problems with pollution. Researchers at the United States Department of Agriculture (USDA) are developing a new type of more efficient packaging than plastic. All made of the same liquid that you mix with coffee to prepare that pinged.
The idea is not simply pouring milk over foods have enough science behind it. The scientists isolated a protein that specifically exists in the beverage, casein. When polymerized, the substance forms structures with pores so small that they can isolate the food from contact with the air 500 times more efficiently than the plastic packaging that we currently have. “The films made based on proteins are potent blockers of oxygen that prevent food spoilage. This could reduce food waste during their distribution,” he said in a statement, Peggy Tomasula researcher at the USDA, and one of the project leaders…
In the future, you can use milk to pack food
One of the most exploited by utilities involved in the project is the creation of small packages that serve to store only portions of food and create no waste. During the project presentation at the annual meeting of the American Chemical Society, for example, Laetitia Bonnaillie, co-author of the research, prepared a coffee placing a mini-pack in a cup with hot water. The plastic dissolves water with high temperature, does not change the taste of the drink and still add some protein to coffee. There were no production of waste. “If you want, you could eat the packaging If not, you can throw away. – The material is biodegradable, will not generate waste,” he said at the event.
Another possibility is the use of the substance in spray form. A spritz and the product pack any food. For now, researchers are testing the technique in breakfast cereals. The carton leaves the crispy flakes longer, without using sugar (technique currently used). The promise is that the product continues to be tested and refined before, in fact, arrive on the shelves for consumers. Involved in the project believe that should take three years for that to materialize – there, do not eat the plastic, please.
