Abstract
Pride of Barbados (Caesalpina pulcherrima) is a legume which is known to contain biologically active components. The study aims at determining the proximate composition, mineral elements and anti-nutrients composition of Pride of Barbados with the view of further understanding its usefulness. The physicochemical, elemental, proximate and anti-nutrient analysis composition of pride of Barbados seeds were determined using standard method of analysis (AOAC) and instrumental method of analysis (AAS). The result of proximate analysis showed 4.970% of Ash, 8.067% of fat, 7.692% of moisture, 9.606% of crude fibre, 1.83% of crude protein. The physicochemical properties of the extracted oil from pride of Barbados seeds shows that the peroxide value is 34.00 mM, saponification value is 65.91 mg KOH/g oil, acid value is 29.17 mg/g, free fatty acid is 14.66 mg KOH/g oil, unsaponification matter is 10.98 mg/g, refraction index is 1.438, smoke fire point 98°C, melting point 26°C, flash point 108°C, fire point 112°C. The mineral elements present in the sample in mg/100 g are Na - 183.31, K - 208.56, Mg - 258.91 and Ca - 175.01. The results also showed that tannin content is 0.485 mg/100 g, oxalate 6.122 mg/100 g and phytate 0.535mg/100g. Therefore, the seed could be a good source for low cost plant protein and mineral elements.
