Thanks to nanotechnology and the smart guys at Texas A&M. But the kicker is keeping grocery food fresh is all a matter of packaging. With the kind of packaging available to the industry today, most of what we buy for food withers in a matter of time (or in the case of bread, days). However, if nano particles could be injected into a special film, lots of our food can last ages. We’re not sure about fresh fruit like bananas being preserved infinitely though, since it’s the freshness that makes them marketable. Banana chips, perhaps?
The new type of film packaging, which has yet to be given a name, is an odd combination of a polymer and clay. Yes, clay as in what’s used for making bricks, etc. The clay mixed with the polymer forms an impenetrable micro-thin protective layer that doesn’t weaken and succumb to oxygen, unlike what most food packaging purveyors have to contend with now.
Long story short, if these microscopic nano bricks enter the mainstream, any type of commercial beverage or food—including your favorite fruit salad—will be sealed in impervious packaging.
As to when this is going to happen, we have no idea.
