Extraction of Elopichthys bambusa Oil with Various Methods

The sensory properties, oil yields, acidity values (AV) and peroxide values (PV) of Elopichthys bambusa viscera oil extracted by 5 methods were analyzed. Results indicated that E. bambusa oils extracted by solvent extraction (SE), enzymatic extraction (EE) and fried extraction (FE) had the best sensory properties. The highest E. bambusa oil yield reached 53.67% by EE, the lowest AV and PV was 5.91mg/g oil and 24.41meq/kg respectively through potassium hydrolysis extraction (PE), while the poorest quality oil was obtained by the boiling hot water extraction (HE), from which the AV and PV values were up to 15.58mg/g oil and 103.78meq/kg, respectively. Overall, EE was the most suitable method for E. bambusa viscera oil extraction.
