Abstract. Soybeans are the dominant oilseed in both U.S. and world markets. During a typical year soybean production comprises over half the worldwide oilseed production (Anonymous 1995).However, according to Dutton (1981) in the early 1940s, soybean oil was considered a poor quality oil, not suitable for food use, and more appropriate for use in industrial paints.
