“…The saponification value of 198 mg KOH/g of oil obtained from Citrus sinensis seeds agrees with values for most vegetable oils ranging from 188 -253 mg KOH/g (Oluba et al, 2008;Otasie and Akinhanmi, 2009;Nwokonkwo, 2013) [8] [13] [14]. This indicates that oil from Citrus sinensis seeds has high potential for soap and shampoos producing purpose (Ku and Mun, 2007) [15].…”

This paper performed the physicochemical and proximate analysis of the extracts isolated from Citrus sinensis from Dutsinma local government area of Katsina state in Nigeria. Characteristics of the seeds were investigated by Association of Official Analytical Chemists (AOACs). The seeds were found to be potential raw materials for livestocks nutrition, cosmetic manufacturing and construction industries. The physicochemical parameters included oil percentage yield, melting point, specific gravity, iodine value, saponification value, peroxide value, free fatty acid value, and acid value. The proximate parameters included moisture, protein, carbohydrate, crude fiber, and ash content. This study concluded that Citrus sinensis seed could be utilized as potential raw material for oil producing industries.

“…It is used both as condiment and thickener in Nigerian local soup, and the industrial scale production of the oil yet to be utilized despite the huge potential [14]. Various studies have reported predominantly high linoleic fatty acid content in egusi melon seed oils [10,14,16]. Due to the unsaturated fatty acid composition of its oil, it was reported to resemble that of safflower [16], corn, cottonseed, sunflower, soybean and sesame oil [10].…”

Investigating “Egusi” (Citrullus Colocynthis L.) Seed Oil as Potential Biodiesel Feedstock

2010

Biodiesel's acceptance as a substitute for fossil-derived diesel has grown the world over. However, the food-fuel debate over conventional vegetable oils has rekindled research interest in exploring lesser known and minor oil crops. In this work, egusi melon seed oil was studied for the first time as a potential feedstock for biodiesel production. Crude egusi melon seed oil was transesterified using sodium methoxide as the catalyst at 60 °C and an oil/methanol ratio of 1:6 to produce its corresponding methyl esters. Egusi melon oil methyl ester (EMOME) yield was 82%. Gas chromatographic analysis of EMOME showed that it was composed mainly of palmitic, stearic, oleic, linoleic and linolenic esters, which is similar to the profile of sunflower, soybean and safflower oil. All the measured fuel properties of EMOME satisfied both the ASTM D6751 and the EN 14214 biodiesel standards. Fuel properties of EMOME were essentially identical with those of soybean, safflower and sunflower biodiesel. Remarkably, the kinematic viscosity of EMOME was measured to be 3.83 mm 2 /s, a value lower than most biodiesel fuels reported in the literature. The potential of egusi melon seed oil as a biodiesel feedstock is clearly presented in this study. OPEN ACCESSEnergies 2010, 3 608

“…One hundred gram samples of whole seed and seed kernels were cleaned, and then coarsely minced at low speed in a blender for 10 s. The condenserincorporated soxhlet extractor was preheated to 80°C, with round bottom flasks properly placed to evaporate water particles, and then set to 70°C (slightly higher than the boiling temperature of the solvent n-hexane 14 ). The seed samples were placed in the thimbles with 250 ml of n-hexane in round bottom flasks, and extracted for 8 h. Excess hexane was evaporated using a rotary evaporator.…”

Egusi seeds are one of the lesser known, but important sources of oil and protein in Africa. Egusi was grown in Malaysia to observe its adaptation to the local environment and to characterize the properties and biodiesel qualities of its seed oil. Oil from dehulled egusi seed (DESO) and whole egusi seed (WESO) were characterized. Extraction from both samples was done by Soxhlet extractor using n-hexane, and transesterified with KOH. Mean methyl ester (ME) yields from three replications averaged 87.3% and 86.7% for DESO-ME and WESO-ME, with cetane numbers of 52.54 and 53.06, respectively. Kinematic viscosities of 4.37 mm 2 /s and 4.39 mm 2 /s were found for WESO-ME and DESO-ME, respectively, making the former suitable as a bio-lubricant. Average flash points of DESO-ME and WESO-ME were 145.3°C and 142.7°C, with mean densities of 876.7 kg/m 3 and 871.0 kg/m 3 , respectively. Six fatty acids were identified via gas chromatography. Total saturated and total unsaturated fatty acids were 20% and 80% for DESO-ME, and 21% and 79% for WESO-ME. Engine performance tests using pure diesel oil (PDO), B5 (5% biodiesel, 95% fossil diesel) and B10 (10% biodiesel, 90% fossil diesel) were carried out. Results showed that B5 and B10 of WESO-ME were better than DESO-MEs. The WESO-ME B5 was very similar in performance to PDO. The torques generated by PDO and WESO-ME B5 were the same. The latter had a lower exhaust temperature. However, power output from WESO-ME B5 was lower (by 0.02 kW) and fuel consumption higher by 7% than for PDO.
