The Irvingia wombolu fruit consists of pulp peel and kernel.

The present work was therefore aimed to determine the nutritional composition of I. wombolu pulp and peel for its potential as a source of human food and animal feed. The proximate amino acid profile and oil characterisation of I. wombolu pulp and peel were carried out using standard methods. The peel contained higher protein (6.31) fat (0.41) ash (4.34) and crude fibre (17.48) than the pulp (4.73 0.38 2.7 and 6.89 respectively). An appreciable amount of essential and non-essential amino acids were obtained with lysine found in highest abundance of 0.0192 and 0.0254 in pulp and peel respectively. Prominent essential oils identified in the peel were ´-tocopherol squalene -tocopherol while the pulp contained squalene and stigmasterol. The presence of essential amino acids; lysine and methionine in pulp and peel of I. wombolu indicate that it can serve as complementary in food and feed materials that lack the two amino acids. The essential oil profile also suggests its potential use in food pharmaceuticals and cosmetics.

Abstract

The Irvingia wombolu fruit consists of pulp peel and kernel. In Nigeria the pulp and peel are usually allowed to rot in order to obtain the kernel used in the preparation of a popular local draw soup. The present work was therefore aimed to determine the nutritional composition of I. wombolu pulp and peel for its potential as a source of human food and animal feed. The proximate amino acid profile and oil characterisation of I. wombolu pulp and peel were carried out using standard methods. The peel contained higher protein (6.31) fat (0.41) ash (4.34) and crude fibre (17.48) than the pulp (4.73 0.38 2.7 and 6.89 respectively). An appreciable amount of essential and non-essential amino acids were obtained with lysine found in highest abundance of 0.0192 and 0.0254 in pulp and peel respectively. Prominent essential oils identified in the peel were ´-tocopherol squalene -tocopherol while the pulp contained squalene and stigmasterol. The presence of essential amino acids; lysine and methionine in pulp and peel of I. wombolu indicate that it can serve as complementary in food and feed materials that lack the two amino acids. The essential oil profile also suggests its potential use in food pharmaceuticals and cosmetics.
