Abstract

Safou (Dacryodes edulis) pulp oil became a new hope for fragile economics of central Africa countries. Raphia sese palm tree (Kolo) produces also an edible vegetable oil of well nutritious value. Various extraction methods were checked for the best yields. By soxhlet extractor using petroleum ether best yields were attained (47% for Safou and 52% for Kolo; dry weight) followed by the Bligh and Dyer method (43.2% for Safou and 50.8% for Kolo). No further improvement was obtained by the enzymatic treatment with Viscozym L (42% for Safou, 51.3% for Kolo). The application of enzyme added to the preservation of oil from oxidation during extraction process.

The prepressed oil will contain no solvent residues, and is moreover expected to contain more nutritionally valuable compounds, which can in turn enhance the oxidativ
