Spondias mombin, Dialium guineense
and Mordii whytii which grow wild and are consumed
raw in the South-west and Middle belt of Nigeria were
analysed for their nutrition potential in meeting some or
all of micronutrients needs of consumers. Nutrient
composition and antinutrional factors of the fresh fruit
pulps were determined using standard methods of AOAC.
Results of proximate analyses showed their moisture content
to be 82.3, 71.5 and 4.0 g /100 g for S. mombin,
M. whytii and D. guineense, respectively.
Their crude protein ranged between 2.6 and 8.3 g, crude
lipid 1.6 to 2.0 g, crude fibre 0.6 to 11.8 g, ash 1.0 to
6.8 g /100 g; and total carbohydrate was 7.9, 8.9 and 84.0 g
/100 g sample for S. mombin, M. whytii and
D. guineense, respectively. The fruit pulps were rich in
sodium (360.0 – 400.0 mg), magnesium (300.0 – 465.0 mg) and
potassium (260.0 - 410.0 mg) /100 g. M. whyti was
rich in calcium (300 mg) and phosphorus (170 mg). Their iron
and zinc content ranged between 2.0 and 4.1 mg and 0.2 – 2.2
mg, respectively; while retinol equivalents ranged between
84.9 and 361.5 μg /100 g fresh sample. The fruit pulps were
low in all antinutritional factors studied and can serve as
good sources of micronutrients.
Key words:
Spondias mombin, Mordii whytii, Dialium guineense,
proximate composition, micronutrient potentials. |
