The most used consumer available margarines in Italy, showed important differecens regarding composition of the saturated (S.F.A.) and trans-unsaturated (T.U.F.A.) fatty acids. The ratio S.F.A./U.F.A. correlated well to the T.U.F.A. content. The margarines with the higher U.F.A. values presented also the higher T.U.F.A. values and corresponded to those prepared from a single seed oil (peanut, corn, sunflower). The monounsaturated fatty acids are composed of a mixture of geometrical and positional isomers with the unsaturation at any C atom between C6 and C16.
意大利最常用的市售人造黄油在饱和脂肪酸（S.F.A.）和反式不饱和脂肪酸（T.U.F.A.）的组成方面存在显著差异。S.F.A./U.F.A. 比值与T.U.F.A. 含量密切相关。U.F.A. 值较高的人造黄油其T.U.F.A. 值也较高，且与由单一植物油（花生、玉米、向日葵）制成的人造黄油相对应。单不饱和脂肪酸由几何异构体和位置异构体的混合物组成，不饱和键位于C6至C16之间的任何碳原子上。
