Proximate composition and fatty acid profile of different tissues of the marine neogastropod Cymbium melo (Solander, 1786)

Abstract

The neogastropod Cymbium melo was collected from Cuddalore landing centre (along south-east coast of India) to analyse the biochemical constituents such as total protein, carbohydrate, lipid, water content and fatty acids in foot, mantle and remaining body tissues. The total protein content was found to be varying from 20.78±1.90% (body tissues) to 30.19±2.02% (mantle) on dry weight basis (DWB). The carbohydrate content was higher in mantle (5.140±1.01% on DWB) and lower in foot (2.59±1.03% on DWB); whereas the lipid content was maximum in mantle (3.390±0.76% DWB) and minimum in foot (2.76±0.92% on DWB). The water content ranged from 76.59 to 83.69%. The order of water content was recorded as 83.48±1.84% in body tissues, 80.53±2.33% in mantle and 76.55±2.26% in foot. The saturated fatty acids were estimated as 32.44% in body tissues followed by 50.96% in foot and 33% in mantle. The monounsaturated fatty acids were recorded only from body tissues (41.06%) whereas the polyunsaturated fatty acids were not recorded in the body tissues and they were estimated as 22.60% in foot and 24.97% in mantle. The fatty acids such as palmitic acid, myristic acid, nonadecylic acid and lauric acid were also reported at varying levels in the different tissues analysed.
