The açaí palm is a tall, slender palm native to swampy floodplains of eastern Amazonia, grown mainly for its small purple fruit, with heart-of-palm and wood as by-products. It needs warm, wet conditions and consistent moisture.
The açaí palm ( ə-SY-ee, Brazilian Portuguese: [asaˈi] ; from Nheengatu asai), Euterpe oleracea, is a species of palm tree (Arecaceae) cultivated for its fruit (açaí berries, or simply açaí), hearts of palm (a vegetable), leaves, and trunk wood. Global demand for the fruit has expanded rapidly in the 21st century, and the tree is cultivated for that purpose primarily.
The species is native to eastern Amazonia, especially in Brazil, mainly in swamps and floodplains. Açaí palms are tall, slender trees growing to more than 25 m (82 ft) tall, with pinnate leaves up to 3 m (9.8 ft) long. The fruit is small, round, and black-purple in color. The fruit became a staple food in floodplain areas around the 18th century, but its consumption in urban areas and promotion as a health food only began in the mid-1990s along with the popularization of other Amazonian fruits outside the region.
There are two harvests: one is normally between January and June, while the other is between August and December, producing larger volumes. In 2022, the state of Pará, which accounts for 90% of Brazil's total açaí economy, produced 8,158 tonnes (17,985,000 lb) of açaí berries, generating US$26 million in revenue. The 2022 production was 209 times greater than the volume produced in 2012.
A powdered preparation of freeze-dried açaí fruit pulp and skin was reported to contain (per 100 g of dry powder) 534 calories, 52 g carbohydrates, 8 g protein, and 33 g total fat. The carbohydrate portion included 44 g of dietary fiber with low sugar levels, and the fat portion consisted of oleic acid (56% of total fats), palmitic acid (24%), and linoleic acid (13%). The powder was also shown to contain (per 100 g) negligible vitamin C, 260 mg calcium, 4 mg iron, and 1002 IU vitamin A.
