It was aimed to investigate the recovery potential of oil and valuable components such as total flavonoid content (TFC) and antioxidant activities with conventional and green extraction methods from edible sunflower oil production wastes. Firstly, Soxhlet extraction was applied on the waste samples from filtration of the oil and then supercritical CO2 ( SC- CO2) extraction was performed to compare extraction yield. The statistical evaluation of the SC- CO2 extraction experiments was conducted with the Minitab Software program. It was concluded that 33% extraction yield was obtained with the mixture of perlite and waste sample, while the highest recovery was observed as 23% for the perlite-free sample. The interaction of independent variables (temperature and pressure) on the recovery yields were determined as significant (p=0.002). Pressure was detected more effective on the valuable substance contents of the extracts than temperature. The most efficient conditions were 40 degrees C and 20 MPa for oil recovery, while 50-60 degrees C and 20 MPa for valuable substance recovery.eninfo:eu-repo/semantics/closedAccessSunflower oilWasteSupercritical CO2 extractionValue added contentUpcyclingAssisted ExtractionChlorogenic AcidOptimizationConference Object
