Laser Food, a company based in Alzira, Spain, will be benefitting from a recent ruling in the United Kingdom very soon. The ruling states that a ban on coating fruit in certain chemicals is now null and void. Essentially, this will involve the decline of the common stickers used on fruits and vegetables in favor of laser-etching. On paper, it is a sensible move considering the cost that goes into the ink, adhesives and paper that make these stickers.
Nevertheless, Laser Food uses a combination of iron oxides and hydroxides to provide the necessary contrast for their etchings to show up on produce. Thus, Laser Food itself may soon be under fire since there are currently no health studies proving iron oxides and hydroxides are safe to ingest.
