University of Missouri scientists create a vegetable oil from soybeans that is much healthier than others

Years of research has proven that saturated and trans fats clog arteries, make it tough for the heart to pump and are not valuable components of any diet. Unfortunately, they are contained in many foods. Now, a University of Missouri research team has developed a soybean which produces oil that is naturally low in saturated and trans fats.

"When we started this research, we were looking at three factors," said Kristin Bilyeu, a researcher with the USDA Agriculture Research Service located in the College of Agriculture, Food and Natural Resources at MU. 'We needed a heart-healthy oil. It needed to be stable with a good shelf life. Finally, it needed to be economically feasible. Oleic acid is a stable component of oil and is not a saturated fat. It does not require hydrogenation, which stabilizes oil but creates trans fats. Oleic acid is the main component of olive oil, but is not a large component in soybean oil. We set out to help the soybean produce more oleic acid in the beans."

Back in the 1970s, scientists discovered that saturated fats, which can be found in foods such as cream, cheese and butter, were bad for the heart. While searching for a substitute, researchers targeted soybean oil. But because soybean oil spoiled when heated, producers had to hydrogenate the oil to keep it stable, thus creating trans fats.

Through natural pollination procedures, Bilyeu and Grover Shannon, professor of plant sciences at MU, developed a soybean oil that was very high in oleic acid, which not only stabilized the oil, but also made it healthier. The natural breeding increased oleic acid in the bean from 20 percent to 80 percent and decreased the amount of saturated fat in the oil by 25 percent.

Additionally, because the new oil is more stable, it doesn't require hydrogenation, which typically rids the oil of Omega-3 fatty acids, which are good supplements for the human heart.

The next step of the research is determining whether this soybean will produce economically viable yields in different environments. Soybeans are grown in nearly every climate in the middle of the country. Preliminary results look promising.

"One of the nice things about this trait of producing oil that is high in oleic acid is that it appears to be very stable," Shannon said. "If you grow the plant in northern Missouri, you typically have 70 percent to 80 percent oleic acid in the soybean's oil. In southern Missouri, the oil is consistently 80 percent oleic acid. Before our work, we saw a lot of variation in the amount of oleic acid that was produced based on the environment."

A byproduct from the study is that this soybean oil not only has health benefits but also can be attractive to the biodiesel market, according to Bilyeu. The high amount of oleic acid gives the soybean oil certain characteristics that make it good for biodiesel. The study is being published in BMC Plant Biology.

NOTE: Oleic is pronounced "O – lay – ick"; Bilyeu is pronounced "Buh – Loo".

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
