Fish oil production in Indonesia is not only sourced from fish raw materials, but also could be processed by products of canning and fish siege through purification process. The result of purification with one process was not satisfy yet for the parameter oxidation quality fulfillment aspect. Therefore, fish oil by products of fish encircling need to be purified more intensively, such as stratified purification one of them through the process of stratified purification. The aim of this study was to improve the quality of fish oil by-product through stratified purification. The multilevel purification of once purification (P1), twice purification (P2), and three times purification (P3) gives varying results on physical properties, oxidation parameters, and fatty acid profiles. The color of the brightest fish oil was found in sample P2, the lowest density was found in sample P3 (0.63 g /cm3), the highest yield was in P1 sample (44.42%), FFA was lowest in P3 sample (0.37%), The lowest PV in the P1 sample (25.59 meq / kg), the lowest TOTOX in the P1 sample (48.11 meq / kg), and the highest PUFA content in the fatty acid composition found in sample P2 (37.02%). Purified sardine oil extracted from by products of fish stamping by three-stage purification, FFA parameters are able to meet the criteria of IFOS 2014 standards, while for PV, AnV, and TOTOX parameters are able to meet IFOMA standards.
