Food Packaging For The Blind May Reduce Food Waste

In the UK more then 4 million tons of good food is thrown out every year. One solution came while looking for a way for blind people to tell if their food is bad. Solveiga Pakstaite came up with the idea of a label that would leave a bump when the food had expired. She used gelatine because it starts off solid then becomes a liquid when expired. Since it expires the same rate as the food, when the bumps produced from the liquid gelatine appear you know its gone bad. For other foods the amount of gelatine is changed altering the speed at which it expires. An interesting idea that may help to reduce good food from being thrown out. Read more at the Guardian.
