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

Abstract

Moringa plant is a plant with increase awareness of its health and nutritional benefits in Nigeria. This study was conducted 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. 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. It was therefore concluded that the findings of M. oleifera seed hull contain nutritive values that may necessitate its usage in alternative feed formulation instead of just remaining an agro waste. Key words: Antinutrients, hull, minerals, Moringa oleifera, vitamins.
