Winged Bean

Winged bean (Psophocarpus tetragonolobus) is cultivated in Southeast Asia, Papua New Guinea, a number of Pacific Islands, and Africa. It is adaptable to tropical climates. The fragile pods are the component of the plant that is most frequently eaten, particularly in Asia, but the leaves, stems, blossoms, seeds, and tuberous roots are also edible and have nutritional value. Another legume with a high seed oil content is the winged bean, which has a protein content of 30–37% and an average oil content of 15%. A good source of energy in the form of starch, the tuberous roots also contain 8–10% protein.
