Fatty acids of soybean oil of different OS cultivars

Objectives: In this study, were investigated fatty acids composition of soybean oil cultivars. Material and Methods: Soybean oil from ten cultivars of the Agricultural Institute of Osijek (Vratarić et al., 1994) from three localities in 1996 year, were extracted with diethyl ether containing butilated hidroxytoluene (Yoshida and Kajimoto, 1989). Fatty acids were determinate by GC standard method (ISO, 1977).Results and discussion: Oil content in soybean cultivars ranged from 19.98 to 20.69%. The amounts of saturated fatty acids in soybean oil cultivars ranged: myristic (0.43-0.78%), palmitic (10.96-11.80%), stearic (3.33-3.92%), arachidic (0.26-0.27%), behenic (0.30-0.31%), and unsaturated: oleic (18.77-22.02%), linoleic (52.98-54.55%) and linolenic (8.64-9.88%). There was no significant difference unsaturated fatty acids content except miristic acid, among localities. Unsaturated fatty acids varied significantly between localities. Conclusion and Perspectives: The experimental results presented here may be useful for the development of grain quality of soybean cultivars.
