Isolation of Cherry Seed Oil Using Conventional Techniques and Supercritical Fluid Extraction.

ABSTRACT: This study aims to compare the suitability of three extraction techniques (cold pressing, Soxhlet and supercritical fluid extraction (SFE)) to isolate oil from cherry seeds. Oils were examined in terms of extraction yield, fatty acids profile, tocopherols yield and antioxidant activity. Additionally, influence of SFE parameters was evaluated using one-factor-at-a-time design with pressure (200-350 bar), temperature (40-70 °C), flow rate (0.2-0.4 kg/h) and particle size (<800 µm and >800 µm). Oil yields ranged from 2.50% to 13.02%, whereas the highest yield was achieved with SFE. Samples were rich in polyunsaturated fatty acids, regardless of the applied extraction technique. The main fatty acids were linoleic (46.32-47.29%), oleic (40.89-41.65%), palmitic (6.56-8.00%) and stearic (2.
