Nutritional Potential of the Fruits of Black Olive (Canarium schweinfurthii Linn) from Plateau State, Nigeria

Abstract

The nutritional potential of the fruits of Black Olive (Canarium schweinfurthii Linn) were assessed by determining proximate and elemental composition. Anti-nutrient factors were also assessed. Results indicate crude fat of the fruit as 64.04%, protein 6.39%, fibre 16.37%, carbohydrate 3.85%, respectively. Mineral analysis revealed the order P>N>Mg>I>K in the fruits. Phosphorus and sodium levels were 1.74 and 1.369 mg/100 g, respectively. The result of anti-nutritional factor revealed high tannins (240 mg/100 g), phytic acid 162 and 26 mg/100 g oxalate which is relatively low. These results suggest that Canarium schweinfurthii variety with thick mesocarp is nutritive despite the presence of some anti-nutritive components like oxalate in very low levels. The final products will contain even less.
