Mangosteen ( Garcinia mangostana )

Fruit Warehouse | Mangosteen ( Garcinia mangostana ) | The Purple Mangosteen belongs to the same genus as the other, less Widely known, mangosteens, Such as the button Mangosteen (G. prainiana) or the charichuelo (G. madruno). As the fruit enlarges over the next two to three months, the exocarp color deepens to darker green. During this period, the fruit increases in size until its exocarp is 6-8 centimetres in outside diameter, remaining hard until a final, abrupt ripening stage.

The Purple Mangosteen (Garcinia mangostana), colloquially known simply as Mangosteen, a tropical evergreen tree is believed to have originated in the Sunda Islands and the Moluccas of Indonesia. The fruit of the Mangosteen is sweet and Tangy, juicy, and somewhat fibrous, with an inedible, deep reddish-purple colored Rind (exocarp) when RIPE. In each fruit, the fragrant edible flesh That surrounds each seed is botanically endocarp, ie, the inner layer of the ovary.

The subsurface chemistry of the Mangosteen exocarp comprises an array of polyphenols and tannins Including xanthones assure astringency That the which discourages infestation by insects, fungi, plant viruses, bacteria and animal predation while the fruit is immature. Mangosteen Produces a recalcitrant seed and must be kept moist until germination to REMAIN viable.

Once the developing Mangosteen fruit has stopped expanding, chlorophyll synthesis slows as the next color phase begins. Initially Streaked with red, the exocarp pigmentation from green to red Transitions to dark purple, Indicating a final ripening stage. If the ambient humidity is high, exocarp hardening may take a week or longer when the aryl is peaking and excellent quality for consumption. However, after Several additional days of storage, ESPECIALLY if unrefrigerated, the arils inside the fruit Might spoil without any obvious external Indications.

The circle of wedge-shaped arils contains 4-8 segments, the larger ones That harbouring apomictic seeds are unpalatable unless roasted. The main volatile components having caramel, grass and butter notes as part of the Mangosteen fragrance are hexyl acetate, hexenol and α-copaene. Mangosteens reach fruit-bearing in as little as 5-6 years, but more require Typically 8-10 years.

The aril is the part of the fruit the which contains the flavor; when analyzed specifically for its nutrient content, the Mangosteen aril is absent of Important nutrient content. Some Mangosteen juice products contain whole fruit puree or polyphenols extracted from the inedible exocarp (Rind) as a formulation strategy to add phytochemical value. The resulting juice has purple color and astringency derived from exocarp pigments, Including xanthonoids disease under study for potential amelioration effects.

Furthermore, a possible adverse effect may occur from chronic consumption of Mangosteen juice containing xanthones. Various parts of the plant have a history of use in folk medicine, mostly in Southeast Asia. It is reputed to have possible anti-inflammatory properties, and may have been used to treat skin infections or Wounds, dysentery or urinary tract infections. Research on the Phytochemistry of the plant is still inadequate to assure the safety or scientific certainty of any of these effects.
