Nutrient and Anti-Nutrient Compositions of Brassica Oleracae Var. Capitata L.

Abstract

The proximate, mineral, vitamin and anti-nutrient compositions of Brassica oleracae var. capitata L. were evaluated using standard procedures. The result for the proximate composition showed the contents of moisture (87.93±0.54%), ash (1.05±0.10%), Crude fibre (3.77±0.11%), Crude protein (1.94±0.10%), Crude fat (0.31±0.06%), Carbohydrate (4.52±0.22%) and calorie value of 28.72kcal/100g. The mineral composition showed the concentration of sodium (176.00±1.16mg/100g), Potassium (678.00±2.65mg/100g), Calcium (28.90±1.51mg/100g), Manganese (0.67±0.02mg/100g), Phosphorus (26.92±0.47mg/100g), Copper (0.05±0.003mg/100g), Iron (2.15±0.10mg/100g) and Zinc (2.11±0.04mg/100g). Vitamins present include vitamin C (56.37±5.21mg/100g), vitamin A (86.30±0.69μg/100g) and Folate (7.14±0.13μg/100g). The anti-nutrient compositions are Oxalate (19.67±0.88mg/100g), Phytate (22.00±0.81mg/100g), Hydrogen cyanide (15.74±0.30mg/100g) and Tannins (2.84±0.60mg/100g). The results showed that Brassica oleracae var. capitata L. contained essential and valuable nutrients which are beneficial to human health
