Proximate Composition and Amino Acid Profile of Selected Accessions of African Yam Bean (Sphenostylis stenocarpa) from IITA, Ibadan:- Chinweokwu Clementina
ABSTRACT
The proximate composition and amino acid profile
of some selected African yam beans accessions was studied. Flour was produced
from these samples (African yam bean accessions). The proximate composition and
amino acid profile were determined using standard methods. The proximate composition
of the samples ranged from 5.33 to 6.32% moisture, 27.98 to 29.46% crude
protein, 3.52 to 4.37 % crude fat, 2.11 to 3.35% crude fiber, 3.86 to 4.59%
ash, 53.37 to 55.47% carbohydrate and 365.44 to 372.56 kcal energy value. The
amino acid composition of the African yam bean accessions ranged from 6.51 to 7
.03 g/ I 00g leucine, 6. JO to 6.8 I g/JO0g lysine, 2.52 to 3.31 g/100g
isoleucine, 0.61 to 1.04 g/l 00g methionine, 2.08 to 3.42 g/1 00g histidine,
2.22 to 3.41 g/1 00g threonine, 2.33 to 3.45 g/l00g proline, 3.01 to 3.44
g/l00g arginine, 2.58 to 3.44 g/l00g tyrosine, 1.39 to 2.24 git 00g cysteine,
3.30 to 3.98 g/100g alanine, 8.93 to 12.34 g/1 00g glutamic acid, 2.92 to 3.47
g/l00g glycine, 2.75 to 3.65 g/l00g serine, 8.15 to 10.36 g/l00g aspartic acid.
This study revealed that African yam bean has great potentials for combating
protein-energy malnutrition and mitigating the effects of essential amino acid
deficiencies and maintain healthy metabolic process hence, its utilization in product development should be encouraged in the food
industry
