The yield and quality of oil extracted from common kilka (Clupeonella cultriventris caspia) through a novel extraction technique with supercritical fluid CO2 and also ethanol co-solvent extraction at 30 MPa pressure and 58°C temperature of for 90 min were compared. Addition of ethanol co-solvent significantly increased the total oil yield (p˂0.05). Moreover, the qualitative characteristics of the extracted oil with ethanol modified the solvent acidity, peroxide and TBA index considerably less than the oil extracted by supercritical fluid CO2. Fatty acid composition of the oil extracted with the two extraction methods showed there was no significant difference in SFA and PUFA fatty acids (p˃ 0.05). In general, the two methods used in this work didn’t considerably affect the fatty acid composition of the extracted oil.
