University of British Columbia researchers have developed a natural, biodegradable wash that removed up to 96% of pesticide residue from fruit and slowed browning and moisture loss. This could mean safer apples, grapes and other fruit that also stays fresh and crisp for days longer. With rising food prices and nearly half of all fresh produce wasted worldwide each year, finding a way to cut pesticide exposure and reduce spoilage could have a big impact. The findings are published in ACS Nano.
