Physicochemical changes of fig fruits quality as Effect by Post-harvest Nano Chitosan Treatments.

The storage of fig fruits has garnered significant attention in the Egyptian market due to concerns about post-harvest quality. In this study, we evaluated the effectiveness of post-harvest chitosan and Nano-chitosan sprays on quality attributes and storability of fig fruits. Ficus carica L. figs were sprayed twice at 0 and 5 days of storage with 0.5% chitosan and Nano chitosan compared to respective controls. At 5-day intervals, the physical and chemical properties of the fruit were evaluated. As a result, nano-chitosan at 0.5% exhibited significant effect as post-harvest treatment. In general, treatment enhanced different properties including reducing weight losses and decay, moreover to preserving maximum firmness and extending shelf life. However, the chemical properties were also indicated that both applied treatments significantly increased the total soluble solids (TSS), total flavonoid contents, total ascorbic acid content, and total phenolic content. In addition to, decreasing the titratable acidity.
