Abstract
Proximate composition and mineral content of the seed and pulp of sugar apple (Annona squaumosa) was investigated. On dry weight (DW) bases, the pulp contain significantly (p < 0.05) higher amount of moisture (70 ± 1.83%), ash (7.5 ± 1.29%), crude fibre (46 ± 2.5%) and soluble carbohydrate (30.30 ± 2.02%) compared to the respective values of 42.50 ± 1.29%, 2.50 ± 0.20%, 36.30 ± 2.00% and 12.60 ± 1.80% for seeds. The crude protein contents did not differ significantly (p > 0.05) difference between the seeds (4.4 ± 0.72%) and the pulp (4.4 ± 1.03%). On the other hand, crude lipid (44 ± 3.06%) and calculated energy (464 kcal/100g) were significantly (P < 0.05) higher for the seeds than the corresponding values (11.5 ± 2.08%; 246 kcal/100g) for pulp. Mineral elements concentrations were low except for Ca in both samples and Mg for pulp. Nutrient densities were low for most elements other than Ca, Mg (for pulp), Fe and Zn, which were > 100%.
