RESUMO: Macauba Palm ( Acrocomia aculeata ) is a promising source of vegetable oil with production capacity of up to 5000 kg/ha. The refini ng process is essential to impurities removal and also to obtain oil with color more appr eciated by consumers. Covering a literature failing, the aim of this study was to in vestigate the Macauba pulp oil refining focusing at bleaching stage by assessing the temper atur effect and amount of commercial adsorbent. Further was evaluated the use of activat ed carbon produced from the endocarp of own Macauba fruit as a partial replacer of bleachin g earths. Conventional methods were employed and results were analyzed considering blea ching capacity, acidity index and phosphorus content. The use of 6% commercial adsorb ent at 90 C led to a bleaching capacity about 84% while the use of a commercial ad sorbent mixed with activated carbon resulted in a bleaching capacity superior to 90% an d with greater percentage of phospholipids removal.
