Abstract:   (7993 Views)
 The effect of different extraction methods (soxtec apparatus, ultrasound, solvent and wet rendering) on yield, quality and fatty acids composition of oil extracted from the offal of common carp (Cyprinus carpio) was compared. For determination of the oil quality, PV, TBA, FFA, conjugated diene, non-enzymatic browning indexes and fatty acids composition were measured. Results showed that soxtec apparatus had the highest efficiency compared to other extraction methods. In addition, ultrasound extraction had higher yield in comparison to solvent methods. Moreover, the wet rendering method had lower oil yield. The quality indexes of oil extracted with ultrasound had significantly lower quality compared to other extraction methods. Hence, the oil extracted with wet rendering methods had better quality. Oil extracted with all of the methods contained high amounts of MUFA, also oil extracted by ultrasound method had the highest content of DHA and EPA as compared with other extraction methods.
