NUTRITIONAL VALUE OF SKELETONEMA COSTATUM (CLEVE, 1873) FROM PARANGIPETTAI, SOUTHEAST COAST OF INDIAAbstract
Present aim to study the biochemical composition, i.e., protein, carbohydrate, lipid, ash, amino acids, fatty acids, vitamins, minerals and Carbon, Hydrogen, Nitrogen from Skeletonema costatum. The biomass of marine diatom (S.costatum) were collected from Parangipettai, Southeast cost of India. The lyophilized powder of S.costatum was used for biochemical analysis. The results of proximate composition showed that the percentage of protein was (12.12%), (carbohydrate 5.94%), (lipid 1.567%) and ash (2.96%). Totally 10 essential and non-essential amino acids were analyzed (24.49mg/g – 22.36 mg/g). The saturated mono unsaturated and poly unsaturated fatty acids was (14.86%), (4.25%) and (10.86%). The vitamins and mineral content was 384.19 mg/g – 459.64 mg/g respectively and 1.627 microgram dry powder of Skeletonema costatum contained the ratio of Carbon (15.04%), Hydrogen (2.59%) and Nitrogen (3.17%) were present. The results of this research showed that S.costatum contained valuable nutritional values and we suggest that in future research on S.costatum can be use food for human.
