Postharvest salicylic acid and chitosan Effects to the improved shelf life of ‘Bada’ sweet cherry

Finding non-chemical (organic) biological compounds such as salicylic acid and chitosan, which are harmless to the consumer and at the same time help to maintain the storage properties of perishable fruit crops, is of interest. Therefore, the effects of salicylic acid (SA) (0, 1, and 2 mmol L-1) on the shelf life and quality of ‘Bada’ cherry fruit during storage were surveyed. Total phenolics (TP), total antioxidant activity (TAA), ascorbic acid content (AAC) and fungal decay incidence (FDI), total titrable acidity (TTA), pH, firmness, and the color surface were evaluated during storage for 14 and 28 days at 2.5±0.5 °C and relative humidity of 85-95 %. SA at all concentrations significantly affected the fruit quality. SA at one mmol L‑1 in combination with 1% chitosan significantly decreased FDI incidence and maintained fruit marketability and firmness. L* and b* color indices significantly increased, and one mmol L‑1 SA induced the rate of yellowish skin color and lighter color. The results of this study can be used for various uses of fresh or processed cherries.
