Abstract
ABSTRACT Oil extracted with hexane from dried African pear (Dacryodes edulis) mesocarp was degummed with 1 or 5% NaOH or H3PO4, and bleached with fuller's earth. Degumming and bleaching produced lighter-colored oils with lower specific gravity and free fatty acid content. However, degummed oils had higher peroxide value (PV) (16.50 mEq/kg for 1% H3PO4-degummed oils) than crude oil (8.00 mEq/kg). Bleaching drastically reduced the PV of degummed oils, with oil degummed with 1% NaOH having the lowest value after bleaching (1.50 mEq/kg). PRACTICAL APPLICATIONS The main thrust of the study is industrial utilization and value-added processing of African pear, a lesser-known African crop of considerable horticultural, nutritional and environmental significance, with a view to promoting its cultivation, reducing postharvest fruit losses and enhancing the income of small-scale farmers that cultivate the crop. Practical applications include establishment of small-scale industries for extracting and refining vegetable oil from oil-rich African pear fruits.
