Food Value

The ripe fruit is widely eaten in India. The edible pulp forms 75% of the whole fruit. Glucose and fructose are the principal sugars in ripe fruit; not even a trace of cane sugar is found. Malic acid is the major acid (0.5% of the wt. of fruit); a small quantity of oxalic acid is also reported. Gallic acid and tannins account for the astringency of the fruit.

The purple colour of the fruit is due to the presence of flavours and anthocyanin pigments occurring as plant diglycosides.


Purple fruit is liked by all and eaten throughout India. A wine is prepared from ripe fruit in Goa. It is used for making squashes and jellies. A good jelly can be made from the purple-fleshed fruits. A jam can also be prepared from pitted fruits. The juice of unripe fruits is used for preparing vinegar.
