Efeito do Ácido Ascórbico em melões 'Orange Flesh' minimamente processados

The aim of this work was to evaluate the application of different concentrations of ascorbic acid on Orange Flesh melon. Whole Melons were sanifi ed with 500 mg L-1 of sodium hypochlorite for 10 minutes and the cuts into cubes with 100 mg L-1 for 1 minute before being tested under different concentrations of ascorbic acid (0, 1, 2 and 3%) in immersion at room temperature for 10 minutes. After drainage, the cuts were packed in PET packages lined with polyethylene fi lm of 18 µm and stored at 5 ± 1°C and 85 ± 5% of RH for 8 days, being evaluated every 2 days. Physicochemical, microbiological and sensorial analyses were performed. The experimental design utilized for the experiment was the completely randomized in factorial scheme. Ten replicates were used for non-destructive analyses and 3 replicates were used for destructive ones. The application of ascorbic acid reduced the loss of mass; the fruits presented a low population of psychrotrophic bacterias, fi lamentous, fungi and yeasts, reduction of soluble solids, pH and fi rmness and, consequently, extended postharvest life of the fruits by 2 days. The appearance, fl avor and taste were also affected. The application of 1% of ascorbic acid was the best treatment for the fresh cuts “Orange Flesh” melons.
