Resumo

Monguba seeds show high content of extractable oil, approximately 54% (w/w). Literature data have reported the recovery of monguba seed oil using conventional methods. However, the use of emerging and environment-friendly methods should be applied, especially the supercritical fluid process. Therefore, we evaluated herein the effect of supercritical CO2 process (15-35 MPa and 40-60 degrees C) on yield, fatty acid profile, tocopherols content, and antioxidant activity of monguba oil. The highest global yield (39.64 g/100 g) was obtained by using 35 MPa and 60 degrees C. Palmitic acid was the main fatty acid, which partially justifies the highest global yield observed at 60 degrees C. Supercritical process operated at 60 degrees C, 35 MPa for 160 min showed global yield equal to the Soxhlet method. The use of supercritical CO2 allows the recovery of high content of high-quality monguba oil without affecting the antioxidant activity and the gamma-tocopherol content. (AU)
