ABSTRACT
This study carried out the evaluation of the nutritional value of Onions (Allium cepa), including the proximate analysis, mineral analysis and phytochemical screening.. The result for proximate analysis of Onions (Allium cepa) showed carbohydrates to be 61.61±2.00, Crude fibre 5.90±0.19, Ash 2.57 ± 0.21, Crude fat 1.71±0.55, Crude protein 10.97 ±1.91, and moisture 17.23±0.28. From the results, Onions has high carbohydrate content and contain moderate value of moisture which indicates a moderately long shelf life. The mineral analysis of onions showed the presence of Iron(0.7±0.3mg/kg), Potassium(75.06±0.45mg/kg), Magnesium(9.7±0.1mg/kg), Manganese(0.15±0.02mg/kg) and calcium(17.1±0.23). Phytochemical screening of onions showed the presence of alkaloid, flavonoid, phenolics, terpenoids, saponins, glycoside, steroids, and the absence of tannins. The Antimicrobial, antioxidant, anti-inflammatory property of onions can be attributed to the presence of these phytochemicals.
