A snapshot of low-linolenic and mid-oleic efforts, and QUALISOY-funded projects:

Select Yield and Quality
As U.S. soybean production has shifted toward the upper Midwest, the average protein and oil levels of soybeans have declined. In 2003 USB began studying protein and oil levels of soybeans and to creating a dialogue that protein and oil levels of soybeans define quality, rather than strictly yield. Today, work continues to ensure the quality of U.S. soybeans for our customers.

Low-Linolenic Acids
In 2002, the U.S. Department of Agriculture’s Agricultural Research Service (USDA - ARS) developed an oil called “Satellite”. Satellite was the first variety tested under the Better Bean Initiative (BBI), the predecessor to the QUALISOY initiative. The Satellite crop was harvested in October 2001 and processed in late December 2001, with analytical and functional testing taking place in 2002. Feedback was positive, and the United Soybean Board (USB) utilized the testing results for the new soybean trait developments.

More recently available low-linolenic-acid soybeans include Monsanto’s VISTIVE® soybeans, Iowa State University’s Low-Linolenic Variety, and Pioneer® soybean variety 93M20. The resulting oils are branded as Asoyia™ Ultra Low-Linolenic Soybean Oil, VISTIVE™ Low-Linolenic Soybean Oil and TREUS™ Low-Linolenic Soybean Oil.

Oleic Acids
In February 2004, the USDA-ARS announced a new germplasm, N98-4445A, that contained increased levels of oleic acid — a monounsaturated fat stable enough for use in salad dressings or frying oils without hydrogenation. With an increased oleic acid level, the germplasm contains only 3 percent linolenic acid, falling in line with the goals of QUALISOY.

Additionally, there is a “first-generation” mid-oleic oil in preliminary testing, which is also part of the Better Bean Initiative. Analytical tests indicate that the oil’s profile contains 2.4 percent linolenic acid, 54 percent oleic acid and 12.6 percent saturates. USB will continue working to lower the level of saturates and increase the oleic level, but this oil is a step in the right direction in terms of eliminating the need for hydrogenation.
