Biorecovery of antioxidants from apple pomace by supercritical fluid extraction
TL;DR: In this paper, the potential of supercritical fluid extraction (SFE) to recover phenolic compounds and antioxidants from apple pomace was explored, and the results showed that the extracts obtained from SFE, carried out on freeze-dried apples at 30MPa and 45MPa for 2h with ethanol (5%) as co-solvent, led to a higher antioxidant activity than conventional extraction technologies such as Soxhlet with ethanol and boiling water maceration.
