Abstract

The development of food waste biorefineries based on clean technologies applied to recover value-added bioactive compounds has been triggered by the need to reduce food waste to mitigate its effects on climate change. This work aimed to develop a sequential extraction process from granadilla seeds in two stages, following the biorefinery approach, using supercritical fluid extraction (SFE) to recover an oil rich in poly-unsaturated fatty acids (PUFA) in a first stage; and phenolic compounds-rich extract from the defatted seeds in a second stage using pressurized liquid extraction (PLE) and ultrasound-assisted extraction (UAE). In the first stage, the optimized SFE at 20 MPa and 40 degrees C yielded 24.84% of a PUFA-rich oil. In the second stage, by comparing PLE with UAE, the results demonstrated that PLE performed at 70 degrees C and 10 MPa with the 75% EtOH was more efficient than UAE to recover phenolic compounds from granadilla seeds.
