Pemurnian Minyak Ikan Lemuru (Sardinella sp.) Menggunakan Sisik Ikan Mas (Cyprinus Carpio) dan Cangkang Simping (Placuna placenta)

Abstract

Generally fish oil as by product of lemuru flouring industry is low quality so it can not be safely consumed. Purification using adsorbent is a method to improve the quality of fish oil. Adsorbents from capiz shell (Placuna placenta) and carp scales (Cyprinus carpio) were used with the concentration of 3 %, 5 %, and 7 %, respectivelly. The results showed purification using adsorbent could reduce free fatty acids from 1,4 - 2,42 %, acid value approximately 2,78 - 4,81 mgKOH/g, peroxide of 2,96 - 5,33 meq/kg, anisidin value from 0,42 - 3,88 mmol/ kg, and the totoks value 6,34 - 14,55 meq/kg, and increased purity from 62,45 - 98,4 %. The best result was obtained from capiz shell at 7 %.
