Abstract

The work aimed to analyse and utilised citrus peels essential oil and pectin from three citrus fruits peels; Orange (Citrus sinensis L.Osbeck), Lemon (Citrus limon L.Osbeck) and Lime (Citrus aurantifolia L.Osbeck).Then, a comparative study of each of the peels are carried out to ascertain the best raw material over what has been existent. This peels are treated using steam distillation for extraction the oil and the pectin is extracted by acid extraction method from the remaining peels. The physiochemical properties of the essential oil and pectin derived from the peels here determined. The properties of the oil ranged from 0.84 to 0.88 for specific gravity, 1.38 to 1.57 for refractive index @ 25 ?C, 122.74 to 158.42mgKOH/g for saponification, 6.96 to 12.93 mg/g for acid value and 41.05 to 84.42 mEq O2/kg for peroxide value. The extracted oils were insoluble in water. Time determined the affect amount of oil extracted at a temperature of 100 ?C, this also presented that orange contains the highest amount of oil in the peels compared to Lemon and Lime. The qualitative and quantitative tests were carried out on the pectin produced from the three samples. The colour ranged from light brown to dark brown, moisture content from 3.2 to 4.4%, pH from 5.2 to 6.1 and ash content from 1.4 to 2.9%. The dry pectin derived from the three samples were insoluble in cold water and soluble in water boiled at 85 ?C for 15 minutes. The result of essential oil derived from the peels were used in producing skin care oil, face wash and insecticide while pectin produced were used as binder in preparation of tablet and stabilizer in the production of yoghurt.
