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 (oleic and 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 (linseed, tung, perilla, walnut, etc.) -mainly used in paints
-Semidrying oils (cottonseed, soybean, etc.) -used in paints, soaps and food
-Nondrying oils (coconut, corn, olive, etc.) -mainly used as food products
Synonyms and Related Terms
huile végétale (Fr.); aceite vegetal (Esp.); olio vegetale (It);
