And palm kernel oil (247 mg KOH gm) (Pearson, 1976). Nonetheless, this saponification worth is within the same array of some edible oils reported by Eromosele and Paschal (2002). Additionally, saponification worth (174.95) of the oil within this investigation is pretty much within the range of (17587) ASTM (2002) specification for oils. As outlined by Pearson (1976), oils with decrease saponification values contain higher volume of extended chain fatty acids. Consequently, the worth obtained for brebra seed oil contained high quantity of greater fatty acids (as it is presented on Table six, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, 3:298 http:springerpluscontent31Page 6 ofTable five 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 worth Refractive index at 40 Iodine worth Peroxide value Ester valueAll values are mean worth of triplicates.Unit Kgm3 kgl mm2s mg KOHgValues Pale-yellow color limpid liquid 0.942 0.926 40.59 0.39 six.mg KOHg174.95 1.GLUT4 manufacturer gI2100 gm mEqKg104.48 6.88 174.chain accounts 92.eight ). The value of viscosity of brebra oil was 40.49 mm2s (as talked about above) is found to become significantly less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, consequently, transesterification reaction is the ideal technique to minimize the viscosity on the oil. The oil below investigation has incredibly 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 within this oil is below the maximum limit (two.0 mg KOHg) of DIN EN ISO 660 and almost inside the range of ASTM specification (0.4 – four.0) of castor oil (ASTM 2002).Table six Fatty acid composition of fatty acid of brebra oil (FAs = fatty acids)No 1 two 3 4 5 Fatty acids Unsaturated FAs Oleic Linoleic Linolenic Arachidonic Eurcic Total Saturated FAs 6 7 8 9 Palmitic Stearic Arachidic Behenic Total C16:0 C18:0 C20:0 C22:0 7.2 1.9 three.3 six.9 19.3 C18:1 C18:two C18:3 C20:4 C22:1 0.6 48.2 27.7 0.eight 3.four 80.7 Carbon number Quantity ( )The low saponification value and acid value imply that the oil is far more suitable for biodiesel since the oil acid value for biodiesel, that is much less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (within the variety, 100-120 gI2100 gm, of DIN) that is higher than the range of 774 gI2100 gm olive oil, 80 gI2 100 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) 44.4 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) (IL-10 Formulation Oladimeji et al. 2001) and 84.eight gI2100 gm refined castor oil (Akpan et al. 2007). One the other hand, the iodine worth of this study was reduce than the range of 11015, 12535, 12540, and 11524 gI2100 gm value of rapeseed oil, sunflower oil, soybean oil and corn oil, respectively. The oil within this study is deemed drying oil considering the fact that drying oils have an iodine value above one hundred gI2100 gm (Duel and Tr 1951). The peroxide worth of brebra oil was six.88 mEqKg. It was greater than the peroxide value of 3.1 mEqKg of money.
