The jackfruit (Artocarpus heterophyllus), also known as jack tree, jakfruit, or sometimes simply jack or jak)is a species of tree in the Artocarpus genus of the mulberry family (Moraceae). It is native to parts of South and Southeast Asia, and is believed to have originated in the southwestern rain forests of India, in present-day Goa, Kerala, coastal Karnataka, and Maharashtra.The jackfruit tree is well suited to tropical lowlands, and its fruit is the largest tree-borne fruit,reaching as much as 35 kg (80 lb) in weight, 90 cm (35 in) in length, and 50 cm (20 in) in diameter.The jackfruit tree is a widely cultivated and popular food item in tropical regions of India, Bangladesh, Nepal, Sri Lanka, Cambodia, Vietnam, Thailand, Malaysia, Indonesia, and the Philippines. Jackfruit is also found across Africa (e.g., in Cameroon, Uganda, Tanzania, Madagascar, São Tomé and Príncipe, Ethiopia, and Mauritius), as well as throughout Brazil, west-central Mexico, and in Caribbean nations such as Jamaica. Jackfruit is the national fruit of Bangladesh. The word "jackfruit" comes from Portuguese jaca, which in turn, is derived from the Malayalam language term, chakka (Malayalam chakka pazham : ചക്കപ്പഴം).[10] When the Portuguese arrived in India at Kozhikode (Calicut) on the Malabar Coast (Kerala) in 1498, the Malayalam name chakka was recorded by Hendrik van Rheede (1678–1703) in the Hortus Malabaricus, vol. iii in Latin. Henry Yule translated the book in Jordanus Catalani's (f. 1321–1330) Mirabilia descripta: the wonders of the East.The common English name "jackfruit" was used by the physician and naturalist Garcia de Orta in his 1563 book Colóquios dos simples e drogas da India.Centuries later, botanist Ralph Randles Stewart suggested it was named after William Jack (1795–1822), a Scottish botanist who worked for the East India Company in Bengal, Sumatra, and Malaysia. The jackfruit has played a significant role in Indian agriculture for centuries. Archeological findings in India have revealed that jackfruit was cultivated in India 3000 to 6000 years ago. It is also widely cultivated in southeast Asia.Thailand and Vietnam are major producers of jackfruit, which are often cut, prepared, and canned in a sugary syrup (or frozen in bags/boxes without syrup), and exported overseas, frequently to North America and Europe. In other areas, the jackfruit is considered an invasive species as in Brazil's Tijuca Forest National Park in Rio de Janeiro. The Tijuca is mostly an artificial secondary forest, whose planting began during the mid-19th century, and jackfruit trees have been a part of the park's flora since its founding. Recently, the species has expanded excessively; its fruits, which naturally fall to the ground and open, are eagerly eaten by small mammals such as the common marmoset and coati. The seeds are dispersed by these animals, which allows the jackfruit to compete for space with native tree species. Additionally, as the marmoset and coati also prey opportunistical.
