And palm kernel oil (247 mg KOH gm) (Pearson, 1976). However, this saponification value is GlyT1 medchemexpress within the identical range of some edible oils reported by Eromosele and Paschal (2002). In addition, saponification value (174.95) on the oil within this investigation is practically inside the range of (17587) ASTM (2002) specification for oils. Based on Pearson (1976), oils with reduced saponification values include higher amount of long chain fatty acids. For that reason, the worth obtained for brebra seed oil contained high quantity of greater fatty acids (since it is presented on Table six, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, three:298 http:springerpluscontent31Page 6 ofTable 5 Brebra oil chemical and physical characteristicsOil physicochemical characteristics Colour Density at 20 Particular gravity at 20 Kinematic Viscosity at 40 Acid value pH value Saponification value Refractive index at 40 Iodine value Caspase 7 Gene ID peroxide worth Ester valueAll values are mean value of triplicates.Unit Kgm3 kgl mm2s mg KOHgValues Pale-yellow color limpid liquid 0.942 0.926 40.59 0.39 6.mg KOHg174.95 1.gI2100 gm mEqKg104.48 6.88 174.chain accounts 92.8 ). The worth of viscosity of brebra oil was 40.49 mm2s (as mentioned above) is located to become much less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, consequently, transesterification reaction would be the greatest technique to minimize the viscosity with the oil. The oil below investigation has really low acid value of 0.39 mg KOHg when compared with cashew nut oil (0. 82 mg KOHg) (Aremu et al. 2006), refined castor oil (0.869) and crude castor oil (1.148) (Akpan et al. 2007), plukenetia conophoora (11.5 mg KOHg) as reported by Akintayo and Bayer (2002), aenniseed (47.six ) by Ohsodi (1992). The acid worth in this oil is beneath the maximum limit (two.0 mg KOHg) of DIN EN ISO 660 and almost within the selection of ASTM specification (0.four – 4.0) of castor oil (ASTM 2002).Table 6 Fatty acid composition of fatty acid of brebra oil (FAs = fatty acids)No 1 2 three 4 five Fatty acids Unsaturated FAs Oleic Linoleic Linolenic Arachidonic Eurcic Total Saturated FAs six 7 eight 9 Palmitic Stearic Arachidic Behenic Total C16:0 C18:0 C20:0 C22:0 7.two 1.9 three.3 6.9 19.3 C18:1 C18:two C18:three C20:4 C22:1 0.six 48.2 27.7 0.eight 3.four 80.7 Carbon quantity Quantity ( )The low saponification value and acid value imply that the oil is more proper for biodiesel because the oil acid worth for biodiesel, that is significantly less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (within the range, 100-120 gI2100 gm, of DIN) which can be greater than the range of 774 gI2100 gm olive oil, 80 gI2 one hundred gm coconut oil, 128 gI2100 gm palm kernel, 4458 gI2100 gm palm oil, 855 palme oleine, 205 gI2 one hundred gm palme stearine, 500 gI2100 gm tallow, 600 gI2100 gm lard, (http:dec2.tec.agrar.tu-muenchen.de pflanzoelrkstandarde.html) 44.four gI2100 gm cashew nut oil (Aremu et al. 2006), 38.1 gI2100 gm citrullus vulgaris (Achinewhu 1990), Hausa melon seed oil (38.50 gI2100 gm) (Oladimeji et al. 2001) and 84.8 gI2100 gm refined castor oil (Akpan et al. 2007). One particular the other hand, the iodine worth of this study was lower than the array of 11015, 12535, 12540, and 11524 gI2100 gm worth of rapeseed oil, sunflower oil, soybean oil and corn oil, respectively. The oil in this study is thought of drying oil due to the fact drying oils have an iodine worth above one hundred gI2100 gm (Duel and Tr 1951). The peroxide worth of brebra oil was six.88 mEqKg. It was higher than the peroxide value of 3.1 mEqKg of money.
