Oil from Dunfield soybeans (Columbia, Mo., 1936) having a very low iodine value, has been examined. Comparison of the constants of this abnormal oil with normal soybean oils indicates no significant differences except in iodine value and refractive index. Based on the calculated composition of the unsaturated acids, the abnormal oil appears to contain a higher percentage of oleic acid, and a lower percentage of linoleic and linolenic acids, than do normal oils. The lowered iodine value does not appear to be correlated with any increase in the stability of the hydrogenated product. The abnormality is attributed to an accumulation of unfavorable varietal, climatic, and pedological factors.
