THE MANGOSTEEN KEEPING QUALITY

Keeping Quality

In dry, warm, closed storage, mangosteens can be held 20 to 25 days. Longer periods cause the outer skin to toughen and the rind to become rubbery; later, the rind hardens and becomes difficult to open and the flesh turns dry.

Ripe mangosteens keep well for 3 to 4 weeks in storage at 40º to 55º F (4.44º-12.78º C). Trials in India have shown that optimum conditions for cold storage are temperatures of 39º to 42º F (3.89º-5.56º C) and relative humidity of 85 to 90%, which maintain quality for 49 days. It is recommended that the fruits be wrapped in tissue paper and packed 25-to-the-box in light wooden crates with excelsior padding. Fruits picked slightly unripe have been shipped from Burma to the United Kingdom at 50º to 55º F (10º-12.78º C). From 1927 to 1929, trial shipments were made from Java to Holland at 37.4º F (approximately 2.38º C) and the fruits kept in good condition for 24 days.
