Resumo

This work investigated the phase behavior of the system sc-CO2 + ethanolic extract of passion fruit bagasse (EEPFB) and the effect of operation modes on the supercritical fluid impregnation (SFI) of phenolic compounds from EEPFB in corn starch aerogels. The total reducing capacity, antioxidant capacity (FRAP and ORAC), piceatannol amount and SFI yield (%) were evaluated. Three of the four system compositions showed the formation of a solid phase. SFI in static mode provided the best TRC, FRAP, and ORAC results. There were no significant differences in the amount of piceatannol and yield (%). The nitrogen adsorption/desorption test possibly indicates the filling of the aerogel pores with EEPFB and images of the aerogel before and after SFI suggest the incorporation of phenolic compounds into the corn starch aerogels through precipitation.
