Supercritical fluid and solid–liquid extraction

Abstract. Distilled white grape pomace (Vitis vinifera var. Garnacha) was subjected to extraction by using two different methods: (1) solid–liquid extraction (SLE) employing 96% ethanol and water and (2) supercritical extraction (SFE) by running carbon dioxide coupled with ethanol as a modifier.Higher phenolic concentrations of extracts were attained by SFE (∼400 ppm), doubling those
