And palm kernel oil (247 mg KOH gm) (Pearson, 1976). On the other hand, this saponification value is inside the identical range of some edible oils reported by Eromosele and Paschal (2002). Furthermore, saponification value (174.95) in the oil within this investigation is pretty much inside the selection of (17587) ASTM (2002) specification for oils. Based on Pearson (1976), oils with reduced saponification values contain higher amount of lengthy chain fatty acids. Therefore, the value obtained for brebra seed oil contained higher quantity of larger fatty acids (Granzyme B/GZMB Protein manufacturer because it is presented on Table 6, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, 3:298 http:springerpluscontent31Page 6 ofTable 5 Brebra oil chemical and physical characteristicsOil physicochemical characteristics Colour Density at 20 Precise gravity at 20 Kinematic Viscosity at 40 Acid worth pH worth Saponification value Refractive index at 40 Iodine worth Peroxide worth Ester valueAll values are mean value of triplicates.Unit Kgm3 kgl mm2s mg KOHgValues Pale-yellow color limpid IL-35 Protein supplier liquid 0.942 0.926 40.59 0.39 six.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 talked about above) is found to become much less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, consequently, transesterification reaction is the very best approach to reduce the viscosity of the oil. The oil beneath investigation has quite 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.five mg KOHg) as reported by Akintayo and Bayer (2002), aenniseed (47.six ) by Ohsodi (1992). The acid value within this oil is below the maximum limit (two.0 mg KOHg) of DIN EN ISO 660 and practically within the range of ASTM specification (0.4 – 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 six.9 19.three C18:1 C18:two C18:3 C20:four C22:1 0.six 48.two 27.7 0.8 three.four 80.7 Carbon quantity Quantity ( )The low saponification worth and acid value imply that the oil is a lot more suitable for biodiesel since the oil acid value for biodiesel, which is less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (inside the range, 100-120 gI2100 gm, of DIN) which is greater than the selection 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 100 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 reduce than the range 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 deemed drying oil considering that drying oils have an iodine worth above 100 gI2100 gm (Duel and Tr 1951). The peroxide value of brebra oil was 6.88 mEqKg. It was higher than the peroxide value of three.1 mEqKg of money.
