Abstract :
This research work evaluated the effect of
air-drying and sun-drying (two processing methods) on
the proximate and macro-elemental constituents of
Alternanthera brasiliana (L.) O. Kuntze leaf. The
proximate analysis was carried out following the
method of by the Association of Official Analytical
Chemists (AOAC). Individual element was estimated
using Atomic Absorption Spectrometer (AAS) machine
LAMOTTE Smart Spectro 2 RMN 26625 and FP 902
(Nanometer: 510NM). The results showed appreciable
quantity of ash, crude fat, protein, energy, and macro
minerals. All the macro mineral elements analyzed viz:
Sodium (Na), Potassium (K), Calcium (Ca), Magnesium
(Mg), and Phosphorus (P) presented higher values in
the air-dried than the sun-dried sample. The sun-drying
method had a reduction effect on all the values of
minerals analyzed but had a positive and significant
effect of the increase on the crude protein. It was
concluded that A. brasiliana was rich in ash, fat, crude
protein, energy, and macro minerals. Air-drying
favoured high yield of minerals while sun-drying gave a
high percentage in crude protein. A. brasiliana,
therefore, could be reckoned with as a promising
candidate in leaf meal preparation for monogastric
animals.
