A tech trick can keep food fresh longer
Can placing a napkin-sized laminated card inside your fridge keep the edibles inside from spoiling too quickly?
A family-owned Boston-based company Nature’s Frequencies claims that sticking its $75 Food Freshness Card in the center of a typical refrigerator, can extend the shelf life of fruits, vegetables and bread up to 50% longer.
It works outside the fridge, too, and can be placed under a fruit bowl, in a bread box or anywhere you want to slow down food storage. The card itself is guaranteed to last at least one year.
The card does not have to touch any of the food, which can remain in their original containers until you’re ready to eat them.
The Food Freshness Card was one of last week’s recipients of the annual Edison Awards, given out to innovative products. It took top honors in the food tech category.
The card was manufactured under three U.S. patents and independently tested by Modern Testing Services in Norwood, Massachusetts.
At the Nature’s Frequencies website, you can watch time-lapse video comparing how fast raspberries, tomatoes, spring mix greens, and other foods go bad, with and without the card.
Nature’s Frequencies says 1.3 billion tons of food are thrown out each year, costing average American family $2,200 a year.
Where you can get it
Individuals can buy the card at the Nature’s Frequencies site for $74.95, though the company is mainly pitching its technology for industrial use. In other words, to the folks who may sell, store or deliver the perishables to your local grocery store.
Though the explanation for how this all works can get rather technical (with some of the details kept under wraps), in simple terms the card inhibits mold and bacteria growth to extend shelf life and keep food fresher. It has about a 3-foot radius.
