Design Process to Obtain Antioxidant Compounds from Goldenberry (Physalis peruviana): Influence of Pretreatment, Extraction and Concentration Processes

摘要

IIn this study, a process design to obtain antioxidant-rich extracts from Physalis peruviana is presented. Simulation procedures based on experimental characterization were used to evaluate the yield of different technologies for pretreatment, extraction and concentration procedures using the Aspen Plus software. Both the conventional and freeze drying technologies were evaluated as pretreatment methods whereas conventional solvent and supercritical fluids were used for the extraction procedure. Finally, the concentration stage was performed by using vacuum distillation or ultrafiltration processes. Eight possible process configurations with mass integration were evaluated with and without energetic integration in technical, economic and environmental terms. In order to compare the simulation results, the polyphenolic compounds from Physalis peruviana fruit were extracted by the different process configurations and the antioxidant activities of extracts were evaluated in order to compare the quality of the final product. This work was performed at Universidad Nacional de Colombia sede Manizales.
