Qualidade de melões ‘Louis‘ armazenados em quatro temperaturas

This research aimed to establish the best temperature for the conservation of ‘Louis‘ melons. Fruit were stored under ambient condition (22°C and 80% RH) and under refrigeration (3°C - 80% RH, 6°C - 90% RH e 9°C - 80% RH) and evaluated for color and resistance of pulp, soluble solids, titratable acidity content, peroxidase, polyphenol oxidase, polygalacturonase and pectin methyl esterase activity and weight loss. ‘Louis‘ melons at 22°C showed greater reduction in soluble solids and titratable acidity content, and had higher activity of the enzyme polygalacturonase, culminating in conservation for 18 days. Melons stored at 6°C preserved the shelf-life for 25 days, showed the highest soluble solids and lower activity of peroxidase and polygalacturonase.
