The fruit of tucumã is composed of a woody core almost black color, containing a white almond paste, an oilseed, and covered with a yellow-orange pulp. Two types of oils are produced from this fruit: the oil of the external pulp and almond oil.

The oil extracted from the pulp contains 25.6% saturated fatty acids and 74.4% unsaturated fatty acids composed of palmitic, stearic, oleic, and linoleic acids. It is also used as an emollient. The value of beta-carotene (which is 180 to 330 milligrams/100g oil) is more concentrated in the oil than in the pulp.

Cosmetic industry

The oil tucuma pulp is used to manufacture soap, body lotions, and hair care products.
