1.0. INTRODUCTION
Ugba also called ukpaka is a popular food delicacy in Nigeria especially among Igbo ethnic group. It is rich in protein and is obtained by a solid state fermentation of the seed of African oil bean tree (Pentaclethra macrophylla Benth).
The natural fermentation of the seed which at present is still done at the house-hold level, renders the production nutritious, palatable and non-toxic (Enujiugha, 2002).
Its production, like many African fermented foods depends, entirely on mixed fermentation by microorganism from diverse source.
Pentaclethra macrophylla Benth is a large woody plant abundant in the rain forest areas of west and central Africa. It’s origin in Nigeria is believed to be around 1937 (Ladipo, 1984); where it is found in the South Nigeria, (Mbajunwa et al., 1998).
―Ugba‖ Pentaclethra macrophylla Benth belongs to the Family Leguminosae and sub-family Microsoideae (Keay, 1989 and NFTA, 1995).
Ugba seeds are irregular and oval; they are flat, black and hard pods. It is composed of oil, protein and small amounts of carbohydrate (Obeta, 1982).
