What is the acai plant?
The acai (Euterpe oleracea) is a palm species that is cultivated for its fruit and edible hearts of palm. Acai palms are native to tropical South and Central America and are commonly found along the Amazon River estuary.
Acai palms have 4–8 slender gray-brown stems, each about 25 meters (82 feet) tall. Each stem bears ringlike leaf scars and a crown of 9–15 compound leaves. Small brown-purple flowers are borne on large branching inflorescences that hang from the tops of the stems. The flowers produce round drupes known as acai berries, which are about 1.5 cm (0.6 inch) in diameter with a single large seed.
The pulp of the fresh fruit is used in sweets and beverages, and the juice is commonly mixed with tapioca. For export, the fruit pulp is usually dried and powdered as a dietary supplement, or flash frozen for smoothies and juices.

Where does the acai plant grow naturally?
The acai palm (Euterpe oleracea) is indigenous to tropical South and Central America. Acai palms are typically found along the Amazon River estuary and are cultivated on floodplains, especially in the state of Pará in Brazil. Acai is difficult to cultivate, and most fruit and palm heart production comes from wild plants in rural estuaries.

What does an acai berry look and taste like?
The acai berry is a small, dark purple, berrylike fruit with a juicy pulp. These fruits grow on tall, slender acai palms that consist of multiple stems, each about 25 meters (82 feet) tall.
Acai fruits have a high fat content, making them very perishable, typically lasting only about a day after harvest. The pulp of the fresh fruit is used in sweets and beverages, including wine, and the juice is often mixed with tapioca. The fruit pulp is usually dried and powdered or flash frozen for smoothies and juices for export.

How is acai harvested from the plant?
Acai fruits are harvested from tall, slender acai palms that consist of multiple stems reaching approximately 82 feet in height. These palms produce clusters of small, round drupes, known as acai berries, each containing a single seed.
Due to the height and slenderness of the palms, children often harvest the fruit because they can climb the trees without breaking them. Each stem can yield up to eight bunches of fruit annually, with each bunch weighing up to 13 pounds. Although some acai is certified fair trade, child labor is widespread among impoverished families who work the harvests.

How do people use acai berries for food and drinks?
People use the pulp of fresh acai fruits in sweets and beverages, including wine, while the juice is mixed with tapioca. In the Brazilian Amazon, acai is a key part of the local diet, often mashed with cassava pulp.
For export, acai fruit pulp is typically dried and powdered for use as a dietary supplement or flash-frozen for smoothies and juices.

Why is acai considered a healthy food or 'superfood'?
The acai fruit is considered a healthy food because it is high in antioxidants and phytochemicals. The acai palm, Euterpe oleracea, is native to the tropical rainforests of Central and South America and produces a small, dark purple, berrylike fruit with a juicy pulp.
Acai fruits have a high fat content, making them highly perishable, typically lasting only about a day after being picked. The pulp from fresh acai is used in sweets and beverages, including wine, while the juice is mixed with tapioca. For export, it is often dried and powdered as a dietary supplement or flash frozen for smoothies and juices. While many health claims exist, including its value as a weight loss aid, most have not been proven.

acai, (Euterpe oleracea), species of palm cultivated for both its fruit and edible hearts of palm. Native to tropical South and Central America, acai palms are common along the Amazon River estuary and are cultivated on floodplains, especially in the state of Pará in Brazil. The plant has long been valued commercially for its high-quality hearts of palm, and its fruits, touted as a superfood, grew in popularity worldwide in the early 21st century.

Physical description
Acai palms consist of 4–8 slender gray-brown stems, each of which is about 25 meters (82 feet) tall and generally no greater than 20 cm (about 8 inches) in diameter. The stems bear ringlike leaf scars and are topped with a crown of 9–15 compound leaves; the leaves measure about 1.2–4 meters (4–13 feet) long. The small brown-purple flowers are either staminate (male) or pistillate (female) and are borne on large branching inflorescences that hang from the tops of the stems. The flowers are pollinated by small bees and flies and produce round drupes known as acai berries. The fruits are about 1.5 cm (0.6 inch) in diameter and feature a single large seed. They usually ripen from green to a deep purple, though the fruit of some populations remains green at maturity. Each acai stem can produce up to eight bunches of fruit a year, each bunch weighing up to 6 kg (13 pounds).
Uses
Fruit and nutrition
Acai fruits have a high fat content and thus are highly perishable, usually lasting only about a day after being picked. Local peoples use the pulp of the fresh fruit in a variety of sweets and beverages, including wine, and the juice is commonly mixed with tapioca. For export, the fruit pulp is usually dried and powdered as a dietary supplement, or it is flash frozen for smoothies and juices. Acai is high in antioxidants and a number of phytochemicals, though most of the health claims about the fruit—including its value as a weight loss aid—have not been substantiated.

Palm hearts
Acai and other members of the genus Euterpe are important commercial sources of palm hearts, also known as hearts of palm, which are eaten as a vegetable. Palm hearts are harvested by removing the growing top of the palm crown; each heart consists of a whitish cylinder of tender immature leaves. Given that acai palms are multistemmed, the harvest can be done without killing the entire plant and thus is considered more sustainable than collection from single-stemmed species.
Other uses
In addition to its commercial importance, acai is also used as a medicinal plant by indigenous and local peoples, and the leaves and stems are useful for thatch and building materials.
Labor issues
Acai is difficult to cultivate, and the majority of fruit and palm heart production comes from wild plants in rural, often labyrinthine estuaries. Given that the palms are so tall and slender, the fruit is frequently harvested by children, who can ascend the plants without breaking them. Despite the risk of deadly or life-altering falls and injuries such as knife wounds or bites from venomous snakes or spiders, researchers in Brazil have noted that the use of child labor is widespread among the impoverished families who work the time-sensitive harvest. Although some acai fruit is certified fair trade, critics of the certification process say that it has done little to eradicate child labor from the industry.
