Food waste is a grand challenge for all of us. So in an effort to help extend the shelf life of foods such as fruits, vegetables, and breads, one company has created a Food Freshness Card™. The technology uses scalar wave technology, a form of electromagnetic wave technology, which is also used in the fresh floral industry and in other applications.
The laminated hologram card is placed in shipping containers, walk-in refrigerators, produce markets, storage areas and even could be used in home refrigerators. It works inside or outside of cold storage and can protect food in a five-foot radius of the card. It does not use any ethylene gas absorption technology or any other controlled atmosphere technology.
