Listing description
Soybean oil is a vegetable oil extracted from the seeds of the soybean (Glycine max). It is one of the most widely consumed cooking oils. As a drying oil, processed
soybean oil is also used as a base for printing inks (soy ink) and oil paints.
Detailed description
To produce soybean
oil, the soybeans are cracked, adjusted for moisture content, heated to between
60 and 88 °C (140–190 °F), rolled into flakes, and solvent-extracted
withhexanes. The oil is then
refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both
liquid and partially hydrogenated are sold as "vegetable oil," or are
ingredients in a wide variety of processed foods. Most of the remaining residue
(soybean meal) is used as animal
feed.
In the 2002–2003
growing season, 30.6 million tons of soybean oil were
produced worldwide, constituting about half of worldwide edible vegetable oil
production, and thirty percent of all fats and oils produced, including animal
fats and oils derived from tropical plants.[1]
Composition
Per 100 g, soybean
oil has 16 g of saturated fat, 23 g of monounsaturated fat, and 58 g of
polyunsaturated fat.[2][3] The major unsaturated fatty acids in soybean
oil triglyceridesare the
polyunsaturates alpha-linolenic acid (C-18:3), 7-10%, and linoleic acid (C-18:2), 51%; and
the monounsaturate oleic acid (C-18:1), 23%.[4] It also contains the
saturated fatty acids stearic acid (C-18:0), 4%, and palmitic acid (C-16:0), 10%.
The high-proportion
of oxidation-prone linolenic acid is undesirable for some uses, such as cooking
oils. Three companies, Monsanto Company, DuPont/Bunge, and Asoyia in 2004 introduced low linolenic Roundup Ready soybeans. Hydrogenation may be used to
reduce the unsaturation in linolenic acid. The resulting oil is called hydrogenated
soybean oil. If the hydrogenation is only partially complete,
the oil may contain small amounts of trans fat.

Drying oils
Soybean oil is one
of many drying oils, which means that
it will slowly harden (due to free-radical based polymerization) upon exposure
to air, forming a flexible, transparent, and waterproof solid. Because of this
property, it is used in some printing ink and oil paint formulations.
However, other oils (such as linseed oil) may be superior
for some drying oil applications.
Fixative for insect repellents
While soybean oil
has no direct insect repellent activity, it is used
as a fixative to extend the short
duration of action of essential oils such as geranium oil in several commercial
products.
