Abstract
Edible crabs of different species are well-known as rich sources of protein and minerals. The present study evaluated the nutritional profile of Portunus pelagicus and Portunus sanguinolentus crabs collected from the coastal Cox’s Bazar district of Bangladesh. The meat and shell parts of both male and female crabs were analyzed for moisture, protein, fat and ash/minerals. The meats contain significantly higher amount of protein (12.72-19.25%), fat (2.78-4.06%), moisture (74.71-79.81%) and lower amount of ash (1.06-2.01%) compared to the shells (0.94-1.55% protein, 0.87-1.33% fat, 47.59-51.01% moisture and 20.99-24.48% ash). Among the minerals, calcium, iron and phosphorus are significantly higher in the shells (6567.11-9463.03 mg/100g, 10.36-31.72 mg/100g and 97.76-127.67 mg/100g, respectively) than in the meats (23.33-233.09 mg/100g, 4.22-8.34 mg/100g and 51.88-63.28 mg/100g, respectively). The findings of the present study suggest that the meat and shell of these crabs could be considered for consumption as excellent sources of protein and minerals essential for infants, young children, adults, pregnant and lactating women.
