Cold plasma and chiral TiO₂ composite coating extend cherry tomato shelf life and degrade pesticide residues
A synergistic system combining dielectric barrier discharge plasma with a chiral titanium dioxide/sodium alginate composite film has demonstrated significant advances in postharvest cherry tomato preservation, reducing microbial counts, extending shelf life by more than four days, and degrading chlorpyrifos pesticide residues to 65.86% – well below regulatory limits – without chemical preservatives.
