| Summary: | A comparative study on the proximate, fatty acids and mine ral compositio n o f Epinephelus
coioides, E. areolalus, Cephalopholis sonnerali and C. miniQ/a we re ca tTied out. T he
results revea led the presence of moisture content ranging from 76.33 to 82.60 %, ash 4.84
to 5. 70 % and total organi c matter 5.64 to 6.62 %. The composition of the extracted oil had
been ana lysed using the GC-FID. The composition fatty acids sho"C(] that total
monounsa tura ted fatty ac id (MUFA; 50.65-5 7.84 %) was the highest fo llowed by saturated
fatty ac id (SFA; 22.33-29. 19 %) and polyunsaturated fatty acid (PUFA; 19. 14-24.87 %) in
both muscle and I iver. Stearic acid and palmati c ac id for SFA, cis-I O-hepladecenoic acid
and ela idic acid for MUFA and al pha-l inolenic ac id and docosahexaenoic ac id (OH A) fo r
PUFA have been identified as predominant fatty ac id. The mineral analysis was done by
using rCP-OES. Minera ls included K (239 1.5-2895 .83 mglkg), Na (507. 17- 1 JU5.5 mglkg),
Mg (20 1.83 -24 1.1 5 mg/kg) and Ca (177.30-354.10 mglkg) whil e Zn, Pb, Mn, Cu and Cd
were present in trace amounts. |
