Analytical characterization and antimicrobial screening of the hilsha [tenualosa ilisha] fish lipid from bay of bengal

ABSTRACT

Muscle Lipid of Hilsha [Tenualosa ilisha] was solvent extracted and characterized with respect to various physical constants e.g. refractive index, moisture, crude fat, crude fibre and ash contents; and chemical parameters e.g. saponification value, saponification equivalent value, acid value, iodine value, acetyl value, peroxide value, thiocyanogen value, Reichert-Meissl value, Polenske value, Hehner value etc. and compared with those of different oils. Results also compared with the data available in literature about pharmacological aspects of Hilsha fish lipid. The oil contain high percentage of palmitic acid followed by myristic acid, palmitoleic acid, stearic acid, oleic acid, respectively, as confirmed by chromatographic examinations. However, investigation lipid sample against the microbial species was inconclusive
