Date palm seeds (Phoenix dactylifera) are discarded as waste after utilization of date flesh by the industries. But the oil from date seed is reported to be rich in unsaturated fatty acids, phenols and tocopherols. Whereas, the date seed powder (DSP) contains high protein and fibre content. Among all the treatment (Control, Soaking, Soaking + Roasting, Roasting) control sample showed highest oil yield (8.2%) was observed. The total fat content in the DSP was 10.7%, Protein (5.5 g/100g) and Total dietary fiber (57.24%), with 52.7% of it was insoluble dietary fiber. The date seed oil is rich in unsaturated fatty acids with oleic acid as the predominant one (51.456%) followed by palmitic acid (12.831%), Myristic acid (10.447%), Lauric acid (10.363%), Linoleic acid (7.20%) and Stearic acid (6.56%). The percent of FFA (Free Fatty Acids) was (0.9 %). The low peroxide value of 1.243 meq O2/kg indicates that date seed oil is fresh and is less susceptible to autoxidation. The iodine value is 73.60g Iodine /100g. The high saponification value of 208.33 mg KOH/ g of oil indicates very high content of low molecular weight triacylglycerol, which is an desirable property to use such oil as bio diesel.The best oil yeild was satisfactory at 2 h extraction time and 2000 microns mesh size by using soxhelt extractor and petroleum ether as solvent.
