ABSTRACT
Presently, in orange peels are discarded as wastes after consumption of edible parts of orange fruits. To get the
highest quality and quantity of orange peel oil, it is necessary to know the suitable methods for drying and the
appropriate form of the peel, whether in the form of pieces, grated or powder. Essential oils are highly concentrated
substances, which are extracted from fruit peels, flowers, leaves, stems, roots and seeds. These oils are often used
for their flavor and their therapeutic or odiferous properties, in wide selection products such as foods,
pharmaceuticals, medicines, perfumery industry and cosmetics. The main objectives of this research is to extract
essential oil from orange (citrus sinensis) peels by two methods: hydro distillation and solvent extraction, to study
the effect of extraction conditions (solvent type, extraction time, and temperature) on oil yield and compare the
results of the two methods, the resulting essential oil was analyzed its physical and chemical properties. From the
results obtained, it was observed that the orange peels could give the maximum yields of essential oil to be 3 % and
2 % when hydro distillation and solvent extraction were employed, respectively, and that was an indication that the
highest yield of essential oil was given by hydro distillation among the methods considered. The physical and
chemical properties values obtained from the characterization of the oil revealed that it could be used in different
process industries for production of other valuable products.
Keywords: Essential oil, Hydro distillation, Effect of temperature.
