The autoxidative stability of triglyceride molecular species was analyzed by determining the residual molecular species after incubating synthesized triglycerides (TGs), interesterified TGs and soybean oil TGs, respectively. The autoxidative stability of each molecular species of TG depends on the degree of unsaturation of TGs and the length of the saturated acyl chain present in glycerides. Thirteen types of soybean oil TG molecular species were isolated by high performance liquid chromatography. Among them, the TG groups most resistant to autoxidation were 2-oleoyl-1( 3)-stearoyl-3(1)-palmitin, 1, 3-dipalmitoyl-2-olein, 2-oleoyl-1(3)-oleoyl-3(1)-stearin and 2-oleoyl- 1(3)-oleoyl-3(1)-palmitin.
