Abstract :
Dacryodes edulis from Makenene (Centre region of Cameroon) were dried in an oven to a final water content of 5.36 %, then stored in polyethylene for 0, 2, 3, 4, 5, 6,7, 8, 9, 10, 11 and 12 months. The dried pulp of safou was then ground before extraction of lipids with hexane. The analysis of oil extract showed that the acid index varies from 4.52 and 10.12 mg KOH/g oil; while the iodine and saponification indexes vary respectively from 52.54 - 58.22 g iodine/100 g of oil, and 170.16 - 211.21 mg KOH/ g oil. The one phase gas chromatographic analysis indicated that the oils are composed of nine to eleven fatty acids with 45.53% saturated, 30.81% mono unsaturated and 23.59% poly unsaturated. In general, the storage of dried pulp in colourless polyethylene bags for 12 months did not significantly (p 0.05) influence the chemical properties of the oil.
