Leaf protein concentrates were derived from two vegetable
species; Allium ceppa and Diplotaxis Tenuifolia. The two
samples were evaluated for their nutritional values using
standard analytical techniques for proximate, amino acid and
functional properties. In proximate analysis, ash,
carbohydrates, proteins, fibre, fats and moisture were
assayed, while amino acid was determined using method of
Sparkman et al. and functional properties determined using
method of coffman Gargia and Beuchat. The highest value of
crude protein was recorded in Allium ceppa while Diplotaxis
Tenuifolia has highest value of Nitrogen free extract. Other
values of proximate analysis were present in significant
proportion. The amino acid profile of the leaf protein
concentrates indicated favourable nutritional balance except
that tryptophan which is the limiting amino acid.The water
absorption capacity, fat emulsion capacity foaming and
foaming stability reveal good functional properties.
