EFFECT OF THE TECHNIQUE OF EXTRACTING OIL FROM THE FRESH ALBUMEN OF RIPE COCONUT PALM (COCOS NUCIFERA L.) ON ITS PHYSICOCHEMICAL CHARACTERISTICS

The present study aims to demonstrate the influence of extraction processes on the oil obtained from the mature albumen of the nut of the coconut hybrid NJM x GVT. Three oil extraction processes were studied. These are the traditional variable temperature extraction methods, at constant temperature (105 ° C) and then the soxlhet extraction method (control method). The physicochemical characteristics of the extracted oil such as pH, density, acid number (Ia), iodine number (Ii), peroxide number (Ip), index of saponification (Ip) and the contents of two major fatty acids, lauric acid (C12) and myristic acid (C14), were determined there. The results indicated that the oil yield obtained with the soxlhet reference method (65.79%) is high than that of the two traditional methods at variable and constant temperature (respectively 38.28 to 39.9%). The oil extracted using these three techniques is acidic (pH
