Abstract
Oils from soybean lines, developed to contain different amounts of palmitate (16:0) and linolenate (18:3), were evaluated for oxidative stability. Oils were extracted in the laboratory from the soybean seeds and refined, bleached, and deodorized. Two replications, separated at the point of conditioning, were evaluated for each genotype, including Hardin 91 (normal beans), P9322 (10.6% 16:0 and <2.6% 18:3), A91-282036 (26.3% 16:0 and 9.8% 18:3), and HPLL (23.2% 16:0 and 3.5 % 18:3). Elevating 16:0 and/or lowering 18:3 increased the oxidative stability of soybean oils as measured by peroxide values. Soybean oils with elevated 16:0 had higher solidification temperatures than did oils with normal 16:0 content, and soybean oils with low 18:3 content had higher solidification temperatures than did oils with normal 18:3 contents.
