This work aimed to describe a full set of procedures to obtain high quality crude and refined pulp oil. Crude oil was extracted by forced pressing of dried, mechanically pulped fruits that were collected directly from the bunch at ripening stage. The preliminary refining process sequentially encompassed degumming, neutralization, bleaching, and deodorization. Identity and quality parameters (fatty acid composition, peroxide value, molar absorptivity at 232 and 270 nm, moisture, refractive index, saponification index, unsaponifiable matter, color, total carotenoids, and solid fat content) were determined in all steps. Crude and refined oils presented about 64% of monounsaturated acids (oleic acid) and 26% saturated acids (mostly palmitic acid). Oil composition and physicochemical characteristics were maintained after refining, rendering high quality oil, suitable for multipurpose employments, such as food processing and biodiesel production.  abiodiesel  aAcrocomia Aculeata  aHigh oleic  aMacaw palm  aVegetable oil refining1 aFAVARO, S.
