Saiful Hossain MollaM. Tamzid AlamM.T. HabibM. Rowshanul 1020081110The fish lipid was extracted from the body muscle (edible
portion) of fresh Lepidocephalus guntea (Ham.) fish and the lipid
content of the fish in size-1 (below 8.5 cm), size-2 (8.5-9.5 cm) and
size-3 (above 9.5 cm) were found to be 2.515, 3.013 and 3.455%, respectively.
The specific gravity and refractive index of the lipid were found to be
0.93 at 30 ° C and 1.467 at 31.5 ° C, respectively. The saponification
value, saponification equivalent, iodine value, peroxide value and acetyl
value of the lipid were found to be 220.325, 254.624, 96.05, 1.993 and
11.32, respectively. The acid value, percentage of free fatty acid as
oleic and unsaponifiable matter present in the lipid were found to be
2.005, 1.008 and 0.593, respectively. The fatty acid composition of the
lipid was determined qualitatively and quantitatively by TLC and GLC.
The analysis revealed that the fatty acid composition of the lipid lies
between C14 to C20. The fish lipid of Lepidocephalus
guntea (Ham.) was found to contain (average value) myristic acid (3.17%),
palmitoleic acid (7.45%), palmitic acid (29.16%), linolenic acid (7.13%),
linoleic acid (5.57%), oleic acid (22.93%), stearic acid (17.42%), arachidonic
acid (7.17%) and arachidic acid in trace amount.]]>AOAC.,199015th Edn.,Pages: 684Pages: 684Ascherio, A., E.B. Rimm and M.N.
