Soursop fruits are dark green, ovoid and have a whitish and aromatic flesh. Since the ripe fruits taste acidic, the fruits are called Soursop. The white pulp is fiber-rich and has a core of indigestible black seeds. The pulp is also used to make fruit nectar, smoothies, fruit juice drinks, as well as candies, sorbets, and ice cream flavorings. Soursop inhibits the growth of cancer cells, so it is also called as the Cancer Fruit.
