Jackfruit, (Artocarpus heterophyllus), evergreen tree (family Moraceae) native to tropical Asia and widely grown throughout the wetland tropics for its large fruits and durable wood. The greenish unripe fruit is cooked as a vegetable, and the brown ripened fruit is eaten fresh for the sweetly acid but insipid pulp surrounding the seeds. The seeds are cooked and eaten locally. Jackfruit is considered a staple food crop in Bangladesh and other areas in South and Southeast Asia. Canned or processed jackfruit has gained popularity as a meat substitute in some places.
