The recovery of active ingredients from vegetable wastes is a very attractive research field for the development of a sustainable economy. In order to revalue the waste from the extraction of oil of Opuntia ficus‐indica seeds, in this study cakes resulting from the pressing were macerated in ethanol and then a Supercritical Antisolvent Fractionation (SAF) technique was used for the recovery and enrichment of the antioxidants present in the ethanolic extract. Catechin, epicatechin, and ferulic acid, as characteristic antioxidant components, were identified and quantified by HPLC in the fractions obtained through SAF. A series of 11 SAF experiments was programed by Response Surface

Methodology (RSM) to optimize the recovery of the original extract and the yield in antioxidants. Optimal SAF conditions were: 15 MPa pressure, 30 g min−1 CO

2 flow rate, and 13.6 MPa,

10 g min−1 CO

2 flow rate for extract mass …
