Scientists at the US Department of Agriculture (USDA) has developed a new kind of food wrap, which not only protects food and keeps it fresh but also acts as a condiment when heated.

Tara McHugh, a research food technologist at the USDA’s research arm in Albany, California, explained to the Associated Press that the wraps are made from a variety of fruits and vegetables, and take on the associated colours and smells.

She added that the project aimed to provide nutritional options for consumers and reduce the waste traditionally associated with packaging. Now, for example, leftover pasta could be stored in a tomato puree wrap, which can later be transformed into a sauce when heated in the microwave.
