In this work, the encapsulation of rice bran oil extracted using supercritical CO2 has been studied. In the first
stage, the emulsification process by high pressure homogenization was studied and optimized. The effect of the
working pressure (60–150 MPa), the composition of the carrier (mixtures of pea protein isolate (PPI) and
maltodextrin (MD), from 50 to 90% of PPI) and the carrier to oil ratio (2–4) on the emulsion droplet size (EDS)
was studied. To minimize the EDS, moderate pressures (114 MPa), a carrier composed mainly by PPI (64%) and
carrier to oil ratios around 3.2 were required. The emulsion obtained in the optimal conditions (EDS ¼ 189
3nm) was dried using different technologies (spray-drying, PGSS-drying and freeze drying). The supercritical CO2
based drying process (PGSS) provided spherical particles that resulted in the smallest average size (but broader
distribution) and lower encapsulation efficiency (53 2%).
