Starting
January 1, 2006, the FDA required that the nutritional panels on
food labels include information on trans fat content. According
to the FDA, there is scientific evidence that consumption of
saturated fat, trans fat and dietary cholesterol raises
low-density lipoprotein (LDL) or “bad” cholesterol levels, which
increases the risk of coronary heart disease.
Low linolenic
soybeans have been developed and the resulting oil already has
been utilized to help food companies reduce or eliminate trans
fats in their products, and high oleic soybean oil is expected
to do more of the same.
Vegetable
oils do vary between different plant species and
varieties—just how much can be shown by gas chromatography.
Mid-West Seed Services, Inc.
(MWSS) invites seed and grain companies interested in their
oilseed composition to submit samples for analysis. Companies
are invited to send single seed samples (such as from a
particular line) or bulk seed samples.
MWSS crushes
the seed submissions and uses an organic solvent to extract the
oil. Derivitization
of the fatty acids in the oil into volatile compounds allow for
analysis by gas chromatography. The results are then given as
the percentage of each fatty acid methyl ester (FAME) of the
total oil.

Please see
the table. In this example, the oil content of conventional
commodity soybeans is provided on the left. Low linolenic
soybeans would have oil content similar to that listed on the
right.
MWSS can
provide oil analysis results in 48 hours.
