| Abstract: | Minyak ikan tuna mengandung asam lemak omega-3 seperti Eicosapentaenoic Acid (EPA) dan Docosahexaenoic Acid (DHA) yang bermanfaat bagi kesehatan tubuh serta mendukung perkembangan otak sehingga berpotensi untuk
dikembangkan menjadi konsentrat omega-3. Pembuatan konsentrat omega-3 ditujukan untuk memisahkan komponen selain asam lemak omega-3. Penelitian ini bertujuan untuk ini menentukan jumlah pelarut dengan minyak yang optimal dalam meningkatkan konsentrat omega-3 ikan tuna (Thunnus sp.) melalui metode kristalisasi suhu rendah berdasarkan parameter oksidasi, bilangan iod, dan persentase omega-3 menggunakan response surface methodology (RSM). Konsentrat omega-3 dengan metode kristalisasi suhu rendah -80ºC dilakukan dengan penambahan pelarut aseton terhadap minyak ikan dengan mengacu hasil formulasi dari RSM. Pembuatan konsentrat omega-3 ikan tuna diperoleh titik optimal menggunakan RSM pada kombinasi pelarut aseton 67,04% dan waktu suhu rendah 37,04 jam. Variabel respon yang dihasilkan pada formulasi ini sudah memenuhi International Fish Oil Standard (IFOS) 2014. Total omega-3 minyak kasar diperoleh hasil sebesar 18,14%, minyak murni sebesar 32,40%, dan konsentrat omega-3 ikan tuna terbaik dihasilkan sebesar 36,33%. Penambahan
pelarut aseton pada proses pemisahan minyak ikan tuna terbukti efektif menurunkan kandungan lemak jenuh. Penurunan lemak jenuh tersebut menyebabkan fraksi kaya omega-3 meningkat, yang ditunjukkan oleh nilai bilangan iod yang lebih tinggi. Tuna fish oil contains omega-3 fatty acids such as Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA), which provide health benefits and support brain development, making it a potential source for omega-3 concentrate production. The preparation of omega-3 concentrates aims to separate non-omega- 3 fatty acid components. This study aims to determine the optimal solvent-to-oil ratio to enhance the omega-3 concentrate from tuna fish (Thunnus sp.) using a low-temperature crystallization method, evaluated through oxidation parameters, iodine value, and omega-3 percentage using Response Surface Methodology (RSM). The omega-3 concentrate was produced by low-temperature crystallization at -80°C with the addition of acetone as a solvent, based on the formulation obtained from RSM. The optimal conditions determined by RSM were achieved at 67.04% acetone and 37.04 hours of low-temperature treatment. The response variables produced under these conditions met the International Fish Oil Standard (IFOS) 2014 requirements. The total omega-3 content of crude oil was 18.14%, purified oil was 32.40%, and the best tuna omega-3 concentrate produced was 36.33%. The addition of acetone in the separation process effectively reduced saturated fat content, thereby increasing the omega-3-rich fraction, as reflected in the higher iodine value. |
