Results showed that the flesh had significantly higher (p < 0.05) levels of protein, fat and moisture (22.32, 7.70 and 58.40%, respectively) than the other body parts analyzed. Equally high in protein were the head (20.11%) and appendages (19.28%), while the exoskeleton recorded the least protein content (14.02%). The flesh had the least (p < 0.05) crude fibre (0.03%) and carbohydrate (7.22%) contents, and conversely had the least energy value (187.50 kcal/g) among the body parts. Ash content was significantly higher (p < 0.05) in the exoskeleton (7.14%), the appendages (7.01%) and the head (6.05%) than in the flesh (4.30%). Individual elements were also unequally distributed among the four body parts investigated: sodium and potassium were more concentrated in the flesh (189.27 mg/100 g and 114.70 mg/100 g, respectively), while calcium and magnesium were highest in the appendages (99.02 mg/100 g and 171.40 mg/100 g, respectively). The concentration of iron was generally low among the body parts; however, it was highest (p < 0.05) in the head. The usual practice of retaining the flesh and discarding the ¡°hard¡± parts (head, exoskeleton and appendages) of prawn during food preparation should be discouraged as this may promote wastage of important nutrients. %U http://www.ccsenet.org/journal/index.php/jfr/article/view/24614
