Szavatosság ellenőrzés

Egy régebbi ötletemhez (Szavatosság ellenőrzés – színváltó festékkel) nagyon hasonló megoldásra bukkantam a Yanko Design site-ján.

Bad meat. There’s nothing nastier. Though the area where I live has a pretty good hold on fresh food packaging and labeling, there’s always some stragglers. According to designer Naoki Hirota, mislabeled food is more than a tiny problem in some shops of the world. Thus, temporal labels are in order.

Or are they?

What this label does, as you can see, is change color over time. Once the meat (or other perishable product) is past it’s due, the label will have turned from white to blue, making the item unscannable. The label has one layer of info for the food with the barcode, and another on top with special ink reactive to ammonia.

The ink is made of non-toxic, safe pigment of purple cabbages.

A device for truly honest food store owners, but as a salvation for the problem of bad food being sold worldwide? Maybe not. Anyone have ideas for other uses for the label?
Or perhaps another solution for the problem?

Given recent (baby milk) problems of late, one might think that there is no true solution to such a situation.

The Freshness of Labels a neve annak a projektnek, melyet tavaly decemberben publikált Naoki Hirota. Egy hasonló megoldást a Timestrip-nél (food retailing) is láthatunk, azaz ismét nem kaptam Nobel díjat… :)
