Abstract

The protein quality of raw leaf, seed and root of Moringa oleifera grown in Rivers State, Nigeria

Author(s): Chioma J. Okereke* and Joyce O. Akaninwor

This study was carried out to ascertain the quality of the root, seed and leaf proteins of Moringa oleifera grown in Rivers state Nigeria. The amino acid compositions were analyzed with the HP 6890 gas chromatography. A total of 17 amino acids were recorded with Glutamate having the highest concentration in g/100g protein (13.53, 14.76, 15.14) and Methionine having the least concentration (0.76, 0.97, 0.95) in the root, seed and leaf of M.oleifera respectively. On comparing the essential amino acids obtained in the root, leaf and seed of M. oleifera to the World Health Organization (WHO) reference pattern for essential amino acids, it was observed of the Limiting amino acids were isoleucine (43.94%), Lysine (62.71%), Isoleucine (55.59%) in the root, seed and leaf of Moringa oleifera. These results show that leaf and seed M. oleifera are good sources of amino acids for both man and livestock. Also, the exceptionally high level of arginine in the M. oleifera seeds makes it an excellent source of fortification of cereal weaning food.
