Soybean oil was hydrogenated under selective and nonselective conditions to give products with iodine values (I.V.) ranging from 85‐115. The products were crystallized at 8C and examined for yield, stability, and fatty acid composition of the winterized oil. Changes in fatty acid composition, formation of trans acids, and yield of winterized oil are approximately linear with the degree of hydrogenation. Stearine fractions, which are 15‐20 I.V. units lower than winterized oil, were further crystallized in solvents to yield liquid oils and hard stearines.
