The effect of heat treatment and germination on the proximate and mineral composition, HCN, tannins, phytk acid and the in-vitro protein digestibility of Mucuna utilis seeds were studied. The raw seeds had aprotein content of 35.4%, 7.7% crude fibre, 3.2% ether extract, 5.8% ash and 47.9% carbohydrates on a dry matter basis. The germinated and dehulled seeds had 40.5% crude protein 2.2% crude fibre, 3.4% ether extract, 7.0% ash and 47.0% carbohydrates, while the heat treated seeds had 34.4% crude protein, 11.9% crude fibre, 3.3% ether extract,9.4% ash and 41.1% carbohydrates. Potassium and iron were the mostabundant minerals while the least were sodium and copper. Germination caused a reduction in the levels of all minerals while heat treatment also caused a reduction in the levels of the minerals but with the exception ofCa, Mg and Zn. Processing caused a reduction in all the levels of anti- nutritional factors assayed. The in-vitro protein digestibility of the raw seeds was 89.4%; 91.7% for the heat treated seeds and 76.0% for thegerminated seeds.Keywords: Mucuna utilis seeds, chemical composition |
