Supercritical fluid impregnation of phenolic compounds from passion fruit bagasse in corn starch aerogels: Phase behavior and effect of operation mode
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.
期刊介绍：
The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics.
Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
