Abstract

Widely consumed forest fruits in Gabon, were analyzed for nutrient and bioactive compositions and their potential contributions to meeting the nutrient requirements of consumers. Edible pulps of Panda oleosa, Gambeya lacourtiana and Poga oleosa contained substantial amounts of bioactive compounds; flavonoids (13.5–22.8 mg/100g), proanthocyanins (2.4–7.6 mg/100g), polyphenols (49.6-77.3 mg/100g) and vitamin C (6.7–97.7 mg/100g). The highest content of β-carotene (76.6 µg/100g) was registered in fruits of Pseudospondias longifolia. The fruits of P. oleosa had the highest essential minerals Fe, Zn and Se. If a child aged 1 to 3 years consumed about 200g or if a non-lactating and non-pregnant woman consumed 300g of P. oleosa, A. lepidophyllus, G. lacourtiana, P. longifolia and P. oleosa, they could obtain substantial RDI ranging between 20-100% for energy, vitamins C and E, iron, magnesium, iron and zinc. Forest fruits can considerably contribute towards the human nutrient requirements. Based on the results of this study, forest foods should be considered in formulating policies governing food and nutrition security in Gabon.
