A WaPo profile of industrial design student Solveiga Pakštaitė and her latest invention, a bio-reactive food expiry label called Bump Mark: Landfills are overflowing with food. Here's a gelatin label that could limit the waste.
Misleading labels are one reason that consumers waste nearly 40 percent of the food they buy — and one of the inspirations behind Bump Mark, a new bio-based food label made with gelatin. As the food in a package starts to decay, so does the gelatin; when it finally expires, the gelatin reveals a layer of bumps. If the label is still smooth, a consumer finally knows unequivocally that food is still safe to eat... By changing the concentration of gelatin, the designer can match the label to specific foods. A weak concentration breaks down faster, and works for foods such as milk and meats that don't last as long. For any given food, the label can be adjusted to degrade at exactly the same rate.[more inside]
You Just Threw Out a Perfectly Good Gallon of Milk Because You Think the "Sell By" Date Means Something. Food waste is a huge problem. Globally, one-third of all food produced goes uneaten. In the US, that's up to 40% (pdf report). What can we do to prevent labeling confusion? And the most important question... should you eat it or is it expired?
