Abstract: Belly flap patin merupakan salah satu dari hasil samping pengolahan fillet ikan patin yang berpotensi dijadikan bahan baku dalam produk minyak ikan. Metode ekstraksi yang digunakan dalam penelitian ini adalah bligh and dyer, wet rendering dan dry rendering. Ekstraksi yang terbaik dilanjutkan dengan pemurnian menggunakan sentrifugasi dan absorben (atapulgit dan bentonit). Produk akhir dibandingkan dengan minyak patin komersil. Analisis kualitas minyak hasil ekstraksi meliputi analisis bilangan peroksida, asam lemak bebas, bilangan anisidin, total oksidasi dan kejernihan minyak. Kadar lemak belly flap patin sebesar 19,53±1,51% dengan asam lemak dominan yaitu asam oleat 20,66 %, asam palmitat sebesar 18,86 % dan asam linoleat sebesar 11,50%. Ekstraksi minyak ikan dari belly flap patin terbanyak adalah metode wet renderring yaitu 12,06± 0,08%. Hasil Pemurnian minyak ikan menghasilkan nilai asam lemak bebas, nilai peroksida, nilai anisidin dan nilai total oksidasi yaitu 5,64%, 11,67 meq/kg, 1,08 meq/kg, dan 24,41 meq/kg dan memiliki nilai transmisi tertinggi.
Patin belly flap is one part of patin fish processing by-products. It is potential to be used as a raw material for fish oil production. The extraction methods were used Bligh and dyer, wet rendering and dry rendering. Crude fish oil obtained from the best extraction method was refined by centrifugation and adsorption (attapulgite and bentonite). The characteristics fish oil purified were compared to commercial patin oil. The fat content of patin belly flap was 19.53±1.51%. The fatty acid of patin fish oil was dominant by oleic acid (20.66%), palmitic acid (18.86%) and linoleat acid (11.50%). Wet rendering was the most effective extraction which yield was 12.06±0.08%. Patin oil refined had free fatty acid value at 5.64%, peroxide value at 11.67 meq/kg, anisidin value at 1.08 meq/kg, total oxidation value at 24.41 meq/kg and it had the highest transmision value.
