The proximate chemical composition and the amino acid content of some Nigerian oil seeds

Abstract

Seven samples of some Nigerian oil seeds have been studied with respect to their proximate composition, calcium and phosphorus contents as well as the amino acid composition which was determined by column chromatography. Three of the groundnut samples were processed in the laboratory. These were then compared with a commercial groundnut cake. The African oil bean seeds, the conophor nuts and the soya beans obtained locally were processed in the laboratory.The chemical composition of the oil seed meals were with few exceptions similar to thosereported in theliterature. The tryptophan and sulphur amino acid contents of the conophor nuts were extremely high compared with the other oil seeds in which the sulphur amino acids were the limiting ones. The lysine contents of the African oil beans and the conophor nuts were exceptionally high compared with others. Glutamic acid followed by aspartic acid and arginine levels were generally high in each of the oil seeds. The implication of these findings are fully discussed.

Amino acid composition, available lysine content and in vitro protein digestibility of selected tropical crop seeds

“…The legumes are generally high in protein and, thus, have the greatest promise as a concentrated source of low cost plant protein [25]. High crude protein levels have also been reported in some lesser known tropical legumes [28][29]. However, protein content of legumes may differ widely, with as much variation within species as among them [30].…”

Effet de l’incorporation de la noix de cajou dans les rations alimentaires sur les performances de croissance des porcs : phases post-sevrage et de croissance

“…Ce qui serait liée à leur digestibilité moyenne (Noblet et al, 2008) et pourrait être un risque laxatif pour l'intestin grêle (Mourot et Lebret, 2009). Par contre, pour d'autres auteurs tels que Fetuga et al (1974) et Mba et al (1974, la diminution de la consommation pourrait être liée à un meilleur équilibre des acides aminés contenus dans la protéine de la noix de cajou. Cette baisse de l'ingestion entraine également la chute de la croissance des animaux.…”

Effect of processing on some antinutritive and toxic components and on the nutritional composition of the African oil bean seed (Pentaclethra macrophylla Benth)

“…The mature seeds are cooked for 6-8 h and processed into ugba, a fermented product used locally as a food condiment or supplement in most southern states of Nigeria. The raw oil bean seed-as reported by various authors (Mba et al 1974;Ikediobi 1981;Achinewhu 1982; Allen and Allen 1981; Jones et a1 1987bontains a high level of protein (230-440 g kg-').
