The Mangosteen fruit is about 3 inches in diameter and roughly rounded with thick leathery leaves attached at the stem end. Its outer shell is thick, smooth, firm and burgundy purple in color. The edible flesh contains an average of five to six snow white triangular segments which can be seedless or contain several flat seeds. The flesh's texture is soft and juicy with a luscious mouthfeel. The fruit has a 16% sugar content and contains volatile compounds which contribute to its floral aromatics and sweet tart tropical flavors with notes of caramel and butter. Ripe fruits will be soft and easy to peel the flesh from the shell.
Mangosteens are available early summer through early winter.
The Mangosteen, botanical name Garcinia magostana, simply referred to as Mangosteen, is an ultra-tropical slow growing evergreen tree that is cultivated for its edible fruit. It belongs to the same genus as the button mangosteen, G. prainiana, and the charichuelo, G. madruno.
The Mangosteen's rind is highly valued for its high concentration of the antioxidant, Xanthones. Since 2002, nutritional supplement purveyors have aggressively marketed high-priced Mangosteen juice blends for their anti-fungal, anti-bacterial, anti-inflammatory properties and ability to combat free radicals and improve immune system.
