Abstract
The quality and safety aspects of two commercially important species Macrobrachium rosenbergii and Harpodon nehereus were evaluated on this study by examining organoleptic properties, proximate composition, total volatile base-nitrogen (TVB-N) and tri methyl amine-nitrogen (TMA-N) contents of the samples. Both the species showed excellent sensory quality with the defect point 1.57 and 1.4 for M. rosenbergii and H. nehereus, respectively. The moisture content of M. rosenbergii and H. nehereus were 80.89±0.23% and 78.56±0.39%; the protein content were 11.76±0.3% and 13.74±0.04%; the lipid content were 2.15±0.007% and 1.89±0.34% and the ash content were 1.24±0.35% and 1.97±0.31% respectively. The TVB-N and TMA-N was found 19.3±0.45 mg/100 g and 3.19±0 mg/100g for M. rosenbergii and 22.37±0.15 mg/100g and 2.09±0.04 mg/100 g for H. nehereus respectively. The result showed the nutritional composition and quality attributes of these two species.
