about the Generally Recognized As
Safe (GRAS) status for the oil. It has
an omega-3 fatty acid called stearidonic acid (SDA), which also may
be metabolized in the body to form
long-chain fatty acids such as eicosapentaenoic acid (EPA), another form
of an omega-3 fatty acid.
The GRAS status says the soybean
oil with SDA may be used as an ingredient in baked foods and baking
mixes, breakfast cereals and grains,
cheeses, dairy product analogs, fats
and oils, fish products, frozen dairy
desserts and mixes, grain products
and pastas, gravies and sauces, meat
products, milk products, nuts and
nut products, poultry products, processed fruit juices, processed vegetable products, puddings and fillings,
snack foods, soft candy, and soups
and soup mixes at levels that will
provide 375 mg of SDA per serving.
The oil is obtained from a bioengineered soybean. The oil contains 15%
to 30% SDA and 5% to 8% gammalinolenic acid (GLA). Neither SDA

nor GLA is found in conventional
soybean oil. The SDA soybean oil
also contains higher levels of alphalinolenic acid (ALA) and palmitic
acid than conventional soybean oil.
It contains lower levels of oleic acid
and linoleic acid. It is 14% to 18%
saturated fat and has no trans fat.
SDA-enriched soybean oil with antioxidants and appropriate handling
has been tested in a variety of food and
beverage products that resulted in acceptable flavor characteristics and the
required shelf life, according to Solae.
According to research presented
at the American Heart Association's Scientific Sessions on Nov. 16
in Orlando, Fla., oil from soybeans
modified through biotechnology increased levels of EPA in red blood
cells. Monsanto and Solae provided
funding for this study.
"This soybean oil could be an effective alternative to fish oil as a
source of heart-healthy omega-3 fatty acids," said William Harris, lead
author of the study and professor of

medicine at Sanford School of Medicine at the University of South Dakota in Sioux Falls, S.D. "We know that
giving pure EPA to people reduces
their risk for heart disease. Presumably, if you gave this special soybean
oil to people, you'd do the same
thing - reduce heart attacks."
Soybeans already contain ALA,
which the body converts to SDA, but
the body converts SDA to EPA more
effectively, resulting in more EPA per
gram consumed.
Researchers developed the new
soybean variety by inserting one gene
from another plant and one from a
fungus to allow the soybean plant to
produce SDA.
One group received 15 grams of
the SDA soybean oil, totaling one
gram of regular soybean oil per day.
A second group consumed 1 gram
of EPA and 15 grams of commodity
soybean oil. A control group received
only commodity soybean oil. Levels
of EPA rose 17.7% in the SDA group
and 19.7% in the EPA group, both
