ABSTRACT
This study was aimed to determine the best time to extract mackerel fish oil by
wet rendering method on the characteristics and profiles of fatty acids in mackerel fish
oil. The design was used non factorial CRD (completely randomized design). The
treatments had given consisted of different extraction times, namely W1 (20 minutes), W2
(30 minutes), and W3 (40 minutes) at 70oC. The analysis parameters consisted of yield,
free fatty acids, peroxide value, iodine, saponification and fatty acid profile (Gas
Chromatography). The analysis showed that the extraction time of 20, 30, and 40 minutes
resulted in yields of 15,41%, 17,66% and 18,33%, respectively. Characteristics of the
quality of mackerel fish oil with different treatment times (20, 30, and 40 minutes) were
resulted in free fatty acids of 1,27%, 1,31%, and 1,41%, peroxide value of 1,51 meq/kg,
1,72 meq/kg, and 1,86 meq/ kg, the iodine value were 102,84 mg iodine/100 g, 100,19
mg iodine/100 g, and 93,87 mg iodine/100 g and the saponification numbers are 124,32
mg KOH / g, 114,58 mg KOH/g, and 107,92 mg KOH/ g. Profile fatty acid of mackerel
fish oil were consisted of saturated fatty acids (SFA), monounsaturated fatty acids
(MUFA), polyunsaturated fatty acids (PUFA), omega 3, and omega 6 at 20 minutes (W1)
of 37,68%, 18,41%, 33,67%, 28,76%, and 4,91%. The 30 minutes treatment (W2) was
35,86%, 17,68%, 33,24%, 28,42%, and 4,82%. The 40 minutes treatment (W3) was
37,67%, 19,07%, 34.97%, 30,00% and 4,97%. Based on the analysis of the chemical
quality parameters of mackerel fish oil according to the IFOS and Codex standards on the
peroxide number. The best treatment was the extraction time of 40 minutes which
produced the highest yield (18,33%) and omega 3 fatty acids (34,97%).
