Abstract

 

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. mombinM. whytiiand 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.
