Abstract

A comprehensive analysis of Landolphia owariensis fruit using standard methods examined both its nutritional composition and anti-nutritional factors. Nutritionally, the fruit contains low levels of protein (0.55%) and fat (0.66%), and its crude fiber (1.20%) which contributes modestly to dietary needs. The carbohydrate content was measured at 15.64%, offering approximately 70.70 kcal per serving, which positions the fruit as a moderate energy source while maintaining a relatively low caloric count. The ash content of 1.57% suggests the presence of minerals, albeit in moderate quantities, underscoring the fruit's overall nutritional profile. Key minerals identified in every 100 grams include Ca(19.00mg), Na(5.30mg), K(320.11mg), P(15.45mg), and Fe(1.52mg). The vitamins content showed the presence of vitamin A, B-vitamins and C. However, the analysis indicated several anti-nutritional components such as tannins (10.52 mg/100g), phytates (8.10 mg/100g), oxalates (6.56 mg/100g), and saponins (4.51 mg/100g). While these compounds may pose some limitations on nutrient absorption, they are generally present in safe concentrations that could even offer health benefits like antioxidant and anti-inflammatory properties. The findings suggest that the fruit could be incorporated into a balanced diet, given its favorable nutritional composition alongside its relatively low anti-nutritional factors.
