Abstract


Minyak ikan adalah sumber terbaik dari omega-3 khususnya EPA dan DHA yang penting untuk kesehatan manusia. Hati hiu kaya akan minyak, sampai saat ini, pemanfaataannya terbatas sebagai sumber squalene atau bahkan dibuang sebagai limbah padahal kandungan asam lemak omega-3nya masih cukup tinggi. Tujuan penelitian ini adalah pembuatan konsentrat omega-3 dari minyak hati ikan hiu. Metode yang digunakan adalah kompleks urea yang dapat memisahkan antara asam lemak jenuh dan tak jenuh dengan perlakuam Aa (rasio urea : asam lemak = 2 :1 suhu 25°C), Ab (rasio urea : asam lemak = 2 :1 suhu 5°C), Ba (rasio urea : asam lemak = 4:1 suhu 25°C) dan Bb (rasio urea : asam lemak = 4 :1 suhu 5°C). Perlakuan terbaik diperoleh pada perlakuan rasio urea: minyak ikan (4:1) dengan suhu pengadukan 5°C (Ba) menghasilkan rendemen sebesar 28,78% dan bilangan iod sebesar 182,48 g/100g serta kadar EPA sebesar 20,04% dan  DHA sebesar 13,59% dengan total asam lemak PUFA sebesar 35,78%. Kesimpulannya pembuatan konsentrat omega-3 dari minyak hati hiu botol dengan metode kristalisasi urea layak diupayakan.
