Abstract

Metode penelitian adalah deskriptif yang bertujuan untuk mengetahui profil gliserida dan identifikasi komposisi asam lemak pada minyak ikan patin. Minyak ikan patin diperoleh menggunakan proses rendering kering (dry rendering). Analisis komposisi asam lemak dengan kromatografi gas (GC) sebelumnya diesterifikasi menggunakan BF3. Total asam lemak jenuh sebesar 49,344%, total asam lemak tak jenuh sebesar 54,524% yang terdiri dari MUFA sebesar 39,101% dan PUFA sebesar 15,423%.Â Ditemukan asam lemak omega 3 yang terdiri dari asam linolenat, asam eikosatrienoat, asam eikosapentanoat (EPA) dan asam dokosaheksanoat (DHA) dan omega 6 terdiri dari asam linoleat, asam Î³-linolenat, dan omega 9 yaitu asam oleat dan asam eikosenoat. Perbandingan omega 3 dan omega 6 pada minyak ikan patin masih dalam rentang syarat perbandingan yang dianjurkan. Dilihat dari komposisi asam lemak minyak ikan patin mengandung asam lemak omega 3 dan omega 6, sehingga sangat baik dikomsumsi untuk meningkatkan kesehatan manusia
