Calyxt, Inc., a Minnesota-based company developing healthier food products to benefit both consumers and growers, today announced the publication of a study in BMC Plant Biology describing the use of genome editing technology to modulate soybean oil composition to have increased shelf-life, higher frying stability and improved nutritional characteristics.
Commodity soybean oil contains high levels of polyunsaturated linoleic and linolenic acid, which contribute to oxidative instability – a problem that has been addressed through partial hydrogenation. However, partial hydrogenation increases levels of trans-fatty acids, which have been associated with cardiovascular disease, according to the U.S. Food and Drug Administration.
Previously, Calyxt generated soybean lines that have oil with increased levels of monounsaturated oleic acid and decreased levels of linoleic and linolenic acid. As a result, the high oleic soybean oil does not require partial hydrogenation. In this study, Zachary L. Demorest and colleagues further improved soybean oil composition by editing additional genes in the soybean genome. The newly produced soybean varieties offer even higher levels of oleic acid and lower levels of linolenic acid (High Oleic, Low Linolenic) to provide greater stability and longer shelf-life.
“This study marks yet another milestone in the commercialization of gene edited foods and demonstrates that gene edited crops can provide significant nutritional benefits to consumers,” said Dr. Feng Zhang, Chief Operating Officer at Calyxt. “We know that consumers are becoming more and more mindful of the foods they eat, and we are striving to bring healthier foods to consumers.”
“In the past, traditional breeding techniques meant that it would take generations to be able to reduce fatty acids and achieve significant improvements in oil composition,” added Dr. Dan Voytas, Chief Science Officer at Calyxt. “TALEN® technology has changed the way we think about crop breeding, and allows us to more quickly and accurately develop foods for the benefit of consumers.”
