Tests confirm oleic acid content of new soybean oil

DES MOINES, IOWA — Test results on oil from high-oleic soybeans grown in 2007 confirmed that the oil contains at least 80% oleic acid, DuPont said March 18. The oil’s high content of oleic acid, a monounsaturated fatty acid, increases the stability of the oil when used in frying and food processing.

The high-oleic soybean oil also consistently demonstrated a linolenic acid content of less than 3%, which should eliminate the need for hydrogenation and result in foods with negligible amounts of trans fat.

Food companies will be able to test the new oil, called Treus High Oleic, following the 2008 growing season. Pending regulatory approvals, it is on track for 2009 commercial introduction in the United States. The Treus brand name represents a family of soy products developed as part of an alliance between Bunge and DuPont. Pioneer Hi-Bred, a DuPont business based in Des Moines, developed the Treus High Oleic oil.

"We are breaking ground on a new oil product that will bring more nutritional benefits to consumers and better performance to the food industry," said William S. Niebur, DuPont vice-president, Crop Genetics Research and Development.

The Treus High Oleic soybean oil compares well with high-oleic oils from other sources. NuSun oil is about 55% to 75% oleic acid, according to the National Sunflower Association, Bismarck, N.D. Canola oil is about 61% oleic acid, according to CanolaInfo, based in Winnipeg, Man., and an information source for consumers, health professionals, chefs, media and educators.

High-oleic soybean oil also may have a future in transportation and industrial applications, according to DuPont. The oil’s high stability may allow companies to develop renewable, environmentally sustainable options to petroleum-based products.
