Papaya is a fast-growing herbaceous tree-like plant whose large oblong fruits carry sweet orange flesh around a central cavity filled with black, gelatinous seeds. The ripe fruit is eaten raw worldwide, while unripe green papaya is widely used as a vegetable and in salads such as Thai som tam.
History & Origins
Papaya was domesticated by Maya and Aztec cultivators in Mesoamerica long before European contact and was carried to Spain and the Philippines by Spanish traders in the mid-16th century. From Manila it spread rapidly across the Asian tropics, becoming established in India, Sri Lanka, and the Pacific islands by the 17th and 18th centuries. Today it is the third most traded tropical fruit globally, with India, Brazil, Mexico, Indonesia, and Nigeria as the leading producers.
