Chitosan and Ascorbic Acid Combination for Extending the Postharvest Quality of Cold-Stored Pitaya
Pitaya is a high-value tropical fruit with a postharvest life constrained by rapid physiological deterioration. This study aimed to evaluate the efficacy of chitosan-based (CH) biopolymeric coatings, enriched with ascorbic acid (AA), on the postharvest quality and preservation of pitaya fruits stored under refrigeration (12 °C). The fruits were subjected to different treatments and evaluated for biometric and physicochemical parameters, including weight loss, total soluble solids, pH, titratable acidity, and the SS/TA ratio throughout storage. The results demonstrated that the coatings significantly reduced weight loss (e.g., 4.15% for the CH4AA treatment) and contributed to the maintenance of quality attributes, delaying senescence-associated processes. Among the treatments, the combination of chitosan with ascorbic acid was the most effective in preserving fruit quality, extending the marketable shelf life from 10 to 20 days. These findings indicate that the use of biopolymeric coatings is a promising strategy to prolong the shelf life and maintain the postharvest quality of pitaya, with potential applications in commercial supply chains.
