Araca boi fruits are edible.  These  have a very distinct aromatic flavour.  The edible portion is white pulp, which has a sour taste.  It is a rich source of vitamin C.  Araca boi fruits are, however,  rarely eaten raw because of their sour taste.  But these are widely used to make juices, soft drinks, ice-cream, preserve and even desserts.

            In Brazil, a few pieces of this fruit are used to savour the Brazilian sugarcane liquor cachaca.  This is a special ritual treat in Brazilian country side.


New plants of araca boi plants are raised from seed.  The seeds, however, loose their viability soon, so these should be used very soon after extraction.

            This fruit has a potential for being developed as an orchard crop and therefore deserves to be promoted.  A couple of projects are already in progress in South America for its domestication.
