A novel biodegradable wash developed by researchers can remove up to 98% of surface pesticides from fresh produce and significantly extend its shelf life, according to a study released today. The treatment, which forms a thin, edible coating, promises to reduce food waste and improve food safety.
“This is a game-changer for the produce industry and consumers,” said Dr. Elena Marchetti, lead researcher at the University of Bologna. “Our wash not only cleans effectively but also creates a protective barrier that slows spoilage.”
Background
Fresh produce is highly perishable: grapes shrivel, apple slices brown, and berries often spoil within days. Many shoppers rinse fruits and vegetables at home, but water alone cannot remove many pesticide residues. Meanwhile, commercial washes often contain harsh chemicals.
The new solution, made from biodegradable polymers and natural compounds, targets both issues. It encapsulates pesticide molecules and forms a breathable film around the fruit, reducing moisture loss and oxidation. “We tested it on apples, grapes, and tomatoes, and saw a 40% increase in shelf life,” added Dr. Marchetti.
What This Means
For consumers, the wash offers a simple way to eat safer produce without buying expensive organic options. For the food industry, it could cut post-harvest losses, which account for nearly 30% of global fruit production. “This technology could save billions of dollars and reduce environmental impact,” noted food safety expert Dr. James Harlow of Cornell University.
Regulatory approval is pending, but the researchers anticipate commercial availability within two years. “We’re already in talks with major growers and retailers,” said Dr. Marchetti. “The potential is enormous.”
