ABSTRACT This study examined whether enzymatic modification of soybean oil (SBO) can be tailored to produce trans‐free fats with physicochemical properties comparable to palm olein, stearin, or palm‐mid fractions (PMFs). US‐grown SBO was modified by lipase‐catalyzed acidolysis using palmitic acid at linearly interpolated substrate molar ratios (C16:0 ...
