The list of vegetable oils includes all vegetable oils that are extracted from plants by placing the relevant part of the plant under pressure, to squeeze the oil out. Although few plants are entirely without oil, the oil from a small set of major oil crops <ref>Economic Research Service (1995-2006). Oil Crops Outlook. United States Department of Agriculture. This publication is available via email subscription.</ref> complemented by a few dozen minor oil crops<ref>B.L. Axtell from research by R.M. Fairman (1992). Minor oil crops. FAO. Retrieved on 2006-11-10.</ref> has become widely used and traded.

Oils may also be extracted from plants by dissolving parts of plants in water or another solvent, and distilling the oil (known as essential oils), or by infusing parts of plants in a base oil (a process known as maceration; see list of macerated oils). The distilled essential oils often have quite different properties and uses to vegetable oils, and are listed in the list of essential oils.

Vegetable oils can be classified in several ways, for example:

  • By source: most, but not all vegetable oils are extracted from the fruits or seeds of plants, and the oils may be classified by grouping oils from similar plants, such as "nut oils".
  • By use: oils from plants are used in cooking, for fuel, for cosmetics, for medical purposes, and for other industrial purposes.

The vegetable oils are grouped below in common classes of use.

[edit] Edible oils

[edit] Major oils

These oils account for a significant fraction of world-wide edible oil production. All are also used as fuel oils.

[edit] Nut oils

Nut oils are generally used in cooking, for their flavor. They are also quite costly, because of the difficulty of extracting the oil.

[edit] Food supplements

A number of oils are used as food supplements, for their nutrient content or medical effect.

[edit] Other edible oils

Coriander seeds are the source of an edible pressed oil, Coriander seed oil.

[edit] Oils used for biofuel

See also: Vegetable oil used as fuel

A number of the oils listed above are used for biofuel (biodiesel and Straight Vegetable Oil) in addition to having other uses. A number of oils are used only as biofuel.<ref>Ethanol and, to a lesser degree, methanol are the other major types of biofuel.</ref><ref name="castoroil">Castoroil.in: Bio fuels.

Although diesel engines were invented, in part, with vegetable oil in mind,<ref name="peanut_diesel">Biodiesel America: Dr. Diesel's Invention. Retrieved on 2006-07-31.</ref> diesel fuel is almost exclusively petroleum-based. Rising oil prices have made biodiesel more attractive. Vegetable oils are evaluated for use as a biofuel based on:

  1. Suitability as a fuel, based on flash point, energy content, viscosity, combustion products and other factors
  2. Cost, based in part on yield, effort required to grow and harvest, and post-harvest processing cost

[edit] Multipurpose oils also used as biofuel

The oils listed immediately below are all (primarily) used for other purposes - all but tung oil are edible - but have been considered for use as biofuel.

[edit] Inedible oils used only or primarily as biofuel

These oils are extracted from plants that are cultivated solely for producing oil-based biofuel.<ref>There are some plants that yield a commercial vegetable oil, that are also used to make other sorts of biofuel. Eucalyptus, for example, has been explored as a means of biomass for producing ethanol. These plants are not listed here.</ref> These, plus the major oils described above, have received much more attention as fuel oils than other plant oils.

[edit] Drying oils

Drying oils are vegetable oils that dry to a hard finish at normal temperatures. Such oils are used as the basis of oil paints, and in other paint and wood finishing applications. In addition to the oils listed here, walnut, sunflower and safflower oil are also considered to be drying oils.<ref name="drying_oils">The Encyclopedia of Painting Materials: Drying oils.

[edit] Other oils

A number of pressed vegetable oils are either not edible, or not used as an edible oil.
