Extraction, Physico-Chemical Analysis and Microbial Activities Evaluation of the Body Lipid of Tripletail (Lobotes surinamensis) of the Bay of Bengal

Abstract

: Due to the discernible variation in the marine fish lipids compositions, the direct and indirect outcomes of it on human health physiology and nutrition have emphasized heightened focus. For this, the inquisition was reported with the extraction of the body lipid of Tripletail ( Lobotes surinamensis ) of the Bay of Bengal by Bligh and Dyer extraction method and different analytical parameters were rummaged and assimilate with those of typical fish lipids. The presence of several fatty acids namely myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), palmitoleic acid (C16:1), oleic acid (C18:1), vaccenic acid (C18:1), linoleic acid (C18:2), linolenic acid (C18:3), arachidonic acid (C20:4), eicosadienoic acid (C20:2), eicosapentaenoic acid (C20:5), docosapentaenoic acid (C22:5) and docosahexaenoic acid (C22:6) etc was confirmed by Gas-Liquid Chromatography (GLC). It revealed that Saturated Fatty Acids (SFA%) were higher than Unsaturated Fatty Acids (UFA%). Moreover total Monounsaturated Fatty Acids (MUFA%) were higher than Polyunsaturated Fatty Acids (PUFA%) i.e. [25.5777% > 12.6850%] and ω-3 Polyunsaturated Fatty Acids (ω-3 PUFA) were higher than ω-6 Polyunsaturated Fatty Acids (ω-6 PUFA) i.e. [8.1113% > 4.5737%] along with higher ω-3/ω-6 ratio (1.77). The muscle of the target specimen was assessed to quantify the minerals content (N, P, K and Ca). Several metals (Fe, Pb, Ni, Co, Cd, Cu, Zn, Mn, Cr, As, Mg) were estimated with the help of Atomic Absorption Spectrophotometric (AAS) method. Additionally, using established techniques, the isolated lipid sample was evaluated for microbial (bacterial and fungal) activity. Thus from the findings, it is resolved with a variety of significant facts relating to nutritional and medicinal aspects.
