Abstract

This study aimed to obtain bioactive compounds from the residue from pineapple (Ananas comosus L. Merril) juice processing, using supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE). The SFE were performed using ethanol as a co-solvent and evaluating different pressure, temperature, and co-solvent percentage. For the PLE, temperature and ethanol percentage were assessed. The best extraction conditions for SFE were 20 MPa, 60 degrees C, and 15 % ethanol, while for PLE they were obtained at 10 MPa, 100 degrees C with 50 % and 75 % ethanol. Both methods presented a higher concentration of bioactives than other recognized vegetable waste sources. However, it was observed that PLE showed a higher overall extract yield, phenolic compounds, flavonoids, carotenoids, and antioxidant activity. The main phenolic compounds identified were caffeic acid and ferulic acid. Therefore, pineapple residue is a potential source of bioactive compounds, and the pressurized liquid extraction technique proved more efficient for their recovery. (AU)
