The effects of edible coatings on the quality of organic apple cv. ‘Golden delicious’ during storage were investigated. Following harvest, the fruits were treated by dipping in various coatings: Nutropit® (14% CaO), Nutropit®+Xedabio (soybean lecithin-based (E322), 0.8%), Bioxeda (an eugenol-based product containing clove oil, 0.8%), Nutropit®+Bioxeda, and Semperfresh (SemperfreshTM, a sucrose-ester based coating, 1%). Organically grown apple cv. ‘Golden delicious’ treated with edible oil-based coatings Xedabio or Bioxeda, combined with Nutropit®, improved postharvest longevity as they effectively delayed color changes in the fruit, and reduced weight loss, shriveling, superficial scald, and rot incidence. Additionally, the combined treatments minimized synthetic pesticide input in the apple agroecosystem, resulting in fruit with zero residues—a critical factor in organic apple production—while maintaining high consumer acceptance.
