Factors important to alkali refining operation of fish oil are optimum soapstock separation to get maximum on removal free fatty acid (FFA) and bleaching. This paper discusses the use of centrifuge and whatman filter paper to get optimum condition magnesol XL for removing polar compound of fish oil alkali refining. The best treatment for soapstocks removal was centrifugation at 15,000 rpm for 2 hours, with yield of neutral fish oil by 82.53%, then for passive filtration using whatman grade no. 54 filter paper could remove soapstocks was 77.63% of alkali fish oil yield. The use of passive filter treatment, optimum conditions to reduce FFA of sardine alkali refining was centrifugation at 5000 rpm for 60 minute, removing 69.92% of FFA. The combination of passive filtration using centrifugation at 5000 rpm for 30 minutes with depth filtration using 1% magnesol XL are the best treatment FFA reduction by 91.05%. At all treatment showed significant (pâ�?¤0.05) for �?£ SFA, �?£ MUFA and �?£ PUFA of fatty acid.
