Vegetable oil
Description
An oil extracted from plant parts, such as seeds, fruits, or nuts. Vegetable oils contain a mixture of glycerides. Drying oils with a high number of unsaturated glycerides (acid oleic and acid linoleic) can oxidize to form hard, insoluble films. Nondrying oils contain mostly saturated glycerides and do not thicken readily.
Examples of vegetable oils:
-Drying oils (oil linseed, oil tung, oil perilla, oil walnut, etc.) -mainly used in paints
-Semidrying oils (oil cottonseed, oil soybean, etc.) -used in paints, soaps and food
-Nondrying oils (oil coconut, oil corn, oil olive, etc.) -mainly used as food products
