CHEMICAL PROPERTIES OF THE OIL EXTRACTED FROM FOUR VARIETIES OF DATE SEEDSGROWN IN AL-KHUMS, LIBYA
Keywords:
Date seed, seed oil extraction, Soxhlet extraction, chemical characteristicsAbstract
Date palm seedsare discarded as waste. Further, our Studies were conducted onfour cultivars date seeds ascultivated inLibya,which namely Omvitity, Taboni, Ami, and Raht. The oil yield was satisfactory at2 h extraction time and 0.5mm size of date seed powder by using soxhelt extractor and toluene as a solvent.The largest percentage of oil yield wasobtained from date seeds(8.9%) for Amicultivar .The acidvalue was ranged (2.02-2.4mg KOH/g)which showed Omvitity seeds had the highacid value(2.4 mg KOH/g)and highpercentage of free fatty acids (1.2 %FFA). While, the high saponification value was( 527.434 mg KOH/g) of oil inTabonicultivar which that the highest of ester value (525.234 mg KOH/ g).
