University trials food freshness technology

A US University has reported the results from its test of a new food freshness technology.

Nature’s Frequencies’ Food Freshness Card is a 15 cm² laminated card programmed with electromagnetic waves and frequencies that are designed to delay the growth of mould (fungi) and bacteria that can feed on and decompose food.

Suitable to use in a refrigerator, in a bread box or under a fruit bowl, the Food Freshness Card lasts as long as the laminated hologram remains intact — approximately one year — and assists in keeping many foods fresher provided they are within 1.2 m of the card. The Food Freshness Card is also suitable for shipping containers, walk-in commercial refrigerators, produce markets and anywhere food is stored.

Bridgewater State University tested the Food Freshness Card throughout its food services department, with 36 cards placed in storage areas, walk-in refrigerators and serving areas.

According to the university’s executive chef: “Since the 36 Food Freshness Cards have been installed throughout our facility, we have not seen any mould on our bread, allowing us to not dispose of any bread. The first month’s savings of bread waste alone ($274) represents about a 6% savings on our bread purchases.”

In addition, the university chef reported that overall waste has been reduced, creating a 2.5% saving on produce purchases. Enhanced longevity and freshness were observed in:

• Blackberries, which usually last 1–2 days and are now lasting 3–4 days
• Raspberries, which usually last 1–3 days and are now lasting 4–5 days
• Strawberries, which usually last 3–4 days and are now lasting 6–7 days

Cucumbers, tomatoes and lettuce were also observed to last at least twice as long.

The Food Freshness Card was awarded the Grand Prix award first runner-up for Best Invention International and Domestic at invention show Inpex.
