Evaluation of proximate content and vitamin profile of Moringa oleifera seed hull

Moringa plant is a plant with increase awareness of its health and nutritional benefits in Nigeria. Ibraheem Ademola Saheed of the Organic and Natural Products Division, Scientific and Industrial Research Department, National Research Institute for Chemical Technology, Zaria, Nigeria conducted a study to examine the nutrient composition of underutilized hull of Moringa oleifera seed.

Proximate composition, antinutrients, minerals and vitamins profile of the hull were determined using standard analytical methods.

His study found that the hull contained crude protein 5.25±0.011%, crude fibre 19.5±0.038%, ash 5.0±0.026%, crude lipid 4.25±0.011%, carbohydrate 55.2±0.062 and moisture content of 10.8±0.033%. Sodium (45.49 mg/100 g) and potassium (24.52 mg/100 g) were the most abundant minerals with appreciable amount of vitamin E and beta-carotene. Alkaloid (0.25%), saponin (10%), oxalate (0.015 mg/100 g) and phytate (0.487 mg/100 g) were found in the hull.

He therefore concluded from his study that M. oleifera seed hull contained nutritive values that may necessitate its usage in alternative feed formulation instead of being an agro-waste.
