Abstract

Telah dilakukan penelitian tentang optimalisasi kondisi pemurnian asam lemak tak jenuh dari minyak ikan lele (Clarias batrachus). Penelitian ini bertujuan untuk mengetahui rasio urea terhadap asam lemak baik pada proses kristalisasi yang menghasilkan konsentrat asam lemak tak jenuh tinggi maupun pada waktu kristalisasi yang menghasilkan asam lemak tak jenuh tinggi. Perlakuan pengaruh rasio urea terhadap asam lemak adalah dengan lima tingkatan rasio masing-masing 1,5:1, 2:1, 2,5:1, 3:1, 3,5:1 dan perlakuan waktu kristalisasi yang terdiri atas tiga taraf masing-masing waktu kristalisasi 24, 30,dan 36 jam. Tiap perlakuan diulang tiga kali. Kadar asam lemak tak jenuh hasil kristalisasirasio urea dianalisis menggunakan metode kromatiografi gas.Hasil yang diperoleh menunjukan bahwarasio urea terhadap asam lemak (2,5:1) menghasilkan asam lemak tak jenuh tertinggi, yakni mencapai 85,59% dengan waktu kristalisasi 24 jam.
