Nutritive values of some edible forest tree seeds in Makurdi-Benue, Nigeria
Journal Title: European Journal of Biological Research - Year 2016, Vol 6, Issue 2
Abstract
The seeds of Adansonia digitata, Afzelia africana, Moringa oleifera, Prosopis africana and Terminalia catappa in Makurdi, Nigeria were analyzed in water-soluble forms to determine their minerals (calcium, phosphorus, potassium, iron, magnesium and iodine) and vitamin (A, C and E) compositions in order to investigate the possible of using seeds for human consumption due to malnutrition in Nigeria. Atomic Absorption Spectrophotometer and Titration Method showed that the seeds were good source of minerals. Potassium (7233.50 ± 3.50 mg/100 g) was the highest from Terminalia catappa seed with the lowest (502.00 ± 1.00 mg/100 g) in Moringa oleifera seed; calcium (789.61 ± 0.01 mg/100 g) in Terminalia catappa seeds while 81.08 ± 0.05 mg/100 g was the lowest from Adansonia digitata seeds; magnesium (687.58 ± 0.01 mg/100 g) as the highest in Terminalia catappa seed while 3.59 ± 0.01 as the lowest in Afzelia africana seed and iron was determined with the highest content of 422.00 ± 1.00 mg/100 g in Terminalia catappa seeds while 3.49 ± 0.03 as the lowest in Afzelia africana seeds. Vitamin A and C evaluated from the seeds were found to be higher in Adansonia digitata seeds while Prosopis africana and Terminalia catappa seeds were low; vitamin E was high (2801.50 ± 1.50 mg/100 g) in Moringa oleifera seeds while Afzelia africana seeds contain the lowest vitamin with 0.74 ± 0.01 mg/100 g. The seeds are very good sources of mineral and vitamin nutrients for human body as useful dietary supplements and good health. There is the need to assess the available of the tree seeds and possible present of anti-nutrients.
