Reducing Polyunsaturation in Oils of Transgenic Canola and Soybean

  • Chapter
Plant Lipid Metabolism

Abstract

A key goal in improving the quality of vegetable oil is reducing its level of polyunsaturated fatty acids, linoleic (18:2) and linolenic (18:3), to result in an oxidatively-stable oil not requiring hydrogenation. This will result in reduced processing cost and the absense of trans fatty acids, by-products of hydrogenation believed to be unhealthy. Since canola and soybean germplasms with the desired low level of polyunsaturation are not currently available, at least, without an agronomic penalty, a transgenic approach was used.
