Proximate, fatty acid and mineral composition of selected deep sea fish species from Southern Java Ocean and Western Sumatra Ocean, Indonesia
MetadataShow full item record
Proximate content, fatty acid and mineral compositions were determined for the ten species of deepsea fish from Southern Java Ocean and Western Sumatra Ocean, Indonesia. The proximate composition was found to be 23.0-24.8 % protein, 1.9-4.1% fat , 0-1.75 % carbohydrate, 1.7-2.4 % ash and 70.1-72.1% water, whereas the fatty acid compositions consisted of 0.86 - 49.63 % saturated fatty acids (SFA), 0.29 - 50.09 % monounsaturated fatty acid (MUFA) and 2.85 % - 46.32 % polyunsaturated fatty acids (PUFAs). Among them, those occurring in the highest proportions were myristic acid (C14:0, 0.12-7.59%), palmitic acid (C16:0, 0.02–20.5%), stearic acid (C18:0, 0.42–49.19), oleic acid (C18:1, 0.29–50.09 %), linoleic acid (C18:2, 0.23– 44.91%), eicosapentaenoic acid (EPA, C20:5n3, 0.41– 4.61%) docosahexaenoic acid (DHA, C22:6n3, 0.28– 3.44%). The rest of the microelements, Cd, Hg, and Pb were all present in amounts below toxic levels.
