This study aimed to evaluate the impact of dipping solutions [Moringa Leaf Extract 5% (MLE), Olive Leaf Extract 5% (OLE) and Calcium Chloride 5% (CaCl2)] on fruit quality of two peach (Prunus persica L. Batsch) cultivars (Blanvio 10 and Plagold 15). The treatments consisted of dipping fruits for 5 min in the corresponding solution followed by 30 minutes drying at room temperature. Then, fruits were stored at 5°C and 95% relative humidity for 2 and 4 weeks of cold storage followed by 2 days at room temperature. Physicochemical traits, antioxidant compounds, sugar content and chilling injury symptoms were analyzed. There were significant improvements in fruits storability resulting from the CaCl2, MLE (5%) and OLE (5%) dipping solutions. These treatments improved firmness, maintained the Soluble Solids Content, and increased the ripening index (SSC/TA). The lowest fruit weight loss was observed in the OLE treatment, whereas the untreated fruits showed the highest loss. The flavonoids, total phenolics, vitamin C and antioxidant capacity showed a gradual decrease during the storage periods. Mealiness and internal browning were the major chilling injury symptoms observed in the two peach cultivars after 4 weeks of cold storage. The applied treatments were efficient and delayed the presence of chilling injury symptoms and fruit decay during the two cold storage periods.
