A greener alternative to adhesive sticker labels on fruits and vegetables may soon arrive in the U.S. The
Food and Drug Administration
is in the process of approving laser etching technology for produce.
A low-energy carbon dioxide laser beam would cut the information (that identifies the produce at the checkout line) into the
outer cells of the peel
, eliminating the need for paper stickers. The etching can’t be removed, making it easier to trace the fruit or vegetable back to its source. New Zealand, Australia and others already
use the technology
and it has been approved in Asia, South Africa, Central and South America, Canada and the European Union.
USDA Agriculture Research Service study
of tangerines and grapefruit found that the laser technology does not enhance decay or water loss. The etching is also too minimal to provide an entry point for food pathogens in the fruit, making it a safe alternative to sticker labels. Testing is also now being done on
tomatoes, avocados and other citrus fruits
The laser labeling won’t change the
taste of the produce
because the etching just goes on the peel.
