Abstract:

Ricinodendron heudelotii and Tetracarpidium conophorum are two non – conventional oleaginous plants belonging to the Euphorbiaceae family. Their kernels contain more than 20% of proteins and are part of the food habit of Cameroonian. This study was undertaken to define high solubility conditions of protein corresponding to the lesser phytate solubility. Hence, the influence of pH, ionic strength (CaCl2) and temperature on protein and phytate solubility of the defatted flours were studied following a factorial design between pH 4 and 9. Results revealed that protein solubility increases, whereas phytate solubility decreases with the pH increase. The pH range (4 – 9) used in this experiment significantly (p<0.05) influenced protein and phytate solubility of the two defatted flours. Maximum solubility conditions of protein (42 – 52g%) corresponding to the lowest phytate solubility (50 – 53mg%) were pH9, CaCl2 0.3M and 35°C. Applications of these conditions reduced protein – phytate interactions and gave protein extracts with low phytate content.
