Researchers develop a biodegradable wash that can remove pesticides and keep fruit fresh longer
Researchers have developed a biodegradable wash made from starch nanoparticles, tannic acid, and iron that removes surface pesticide residues and extends the shelf life of fruit. The study demonstrates higher pesticide removal rates than tap water and reduced weight loss in grapes and apples, though the authors note that further testing and regulatory approval are required before consumer use.
