This study investigates the effectiveness of macaúba oil extraction using supercritical carbon dioxide, focusing on determining operational parameters such as temperature and pressure that maximize the quality and yield of the extract obtained. The extraction was carried out using freeze-dried macaúba pulp, under varying conditions of pressure and temperature. The overall yield isotherms of macaúba oil obtained, the solubility of the solute, composition of fatty acids, triglycerides, phenolic compounds, in addition to the antioxidant capacity and antimicrobial activity, were evaluated, before and after extraction. The results demonstrated that, under the conditions evaluated, the extraction process achieved maximum oil yields of 24.4 %, with a predominance of unsaturated acids rich in antioxidants and high concentrations of oleic acid (64.12 %), β-carotene (80.06 mg/kg) and α-tocopherol (114.66 mg/100 g of oil). This promising method offers a sustainable alternative for the production of compounds with high nutritional value, highlighting its potential for industrial applications.
