Buriti Oil - Ecology and Popular Uses

Buriti Oil - Mauritia Flexuosa, Arecaceae

Buriti

POPULAR USES
The buriti is a palm with multiple uses. New leaves and their stalks are frequently employed in crafts, such as baskets, and the fruit pulp is processed into a juice called “wine” and sweets, which are a popular food in the Amazon region. The buriti oil, which is edible, is used in frying and applied to skin to treat sunburns, which causes immediate relief and helps the skin to heal. Due to its powerful ability to detoxify and combat allergic reactions, the caboclos treat snake and scorpion bites by applying the oil to the wound. The oil is also used to treat asthma by ingesting half a spoon of oil per day, which reduces coughing and relieves breathing. Currently, the fruit pulp is commercialized in local markets, in the countryside, for the production of “wine” that replaces açaí during the rainy period, which is from January to June and is the low production period for açaí. There are companies that sell the fresh fruit pulp for the extraction of oil; others prefer the dry pulp, called buriti flour, because the pulp is very perishable.

ECOLOGY

Buriti Tree

Buriti is a palm tree (Mauritia vinifera and M. flexuosa), which dominates expansive areas and covers nearly all of central Brazil and the lowlands of southern Amazonia, where there are streams. It is an elegant tree that can reach 35 meters and forms large leaves with a rounded crown. The flowers are yellowish, and appear from December to April. Its fruits are ellipsoidal, chestnut colored, and have a surface coated with shiny scales. The fruits have a yellow flesh that covers a hard oval seed, which is edible. The trees fruit from December to June. The buriti palm naturally occurs alone or in communities, and requires an abundant supply of water.
For this reason, they dominate floodplains and swamps where the soil is soft and moist. The location where they grow is the result of the their seeds being dispersed by water when an area is inundated. This species is dioecious; plants have only male or female flowers. Only individuals with female flowers form fruits.
Approximately 60 female and 80 male buriti palms occur in one hectare. An adult palm can produce up to 200 kg of fruit, which can be processed into 30 kg of flour or 5 to 6 liters of finally extracted oil (the flour contains 22% oil). Assuming an average of 60 buriti palms per hectare, 300 to 360 liters of oil can be extracted per hectare. The reproductive cycle occurs every two years, but there are communities that mange their natural buriti groves by cutting and removing the small and dried infructescences (the stalks with fruits) and removing natural competitors, and thus have a year of low productivity followed by a year of high productivity.
