Abstract

Supercritical fluid extracts of hazelnut seed coat were obtained using solvents (methanol, ethanol and acetone) and methanol and ethanol containing sodium hydroxide (10%) catalyst. The yields of supercritical methanol, ethanol and acetone extractions were 41.9, 52.3 and 60.9%, respectively, at 563 K. The yield of supercritical acetone extraction has been increased from 44.0 to 60.9% as the temperature increased from 523 to 563 K. The yield of supercritical methanol extraction has been increased from 41.9 to 60.0% in the catalytic run.
