Vegetable oils contain different fatty acid patterns that depend largely on the respective plant species. The proportions of saturated, monounsaturated and polyunsaturated fatty acids are not the same in all oils.
Fatty acids are divided, among other things, according to the position of their double bonds into the omega-3, omega-6 and omega-9 families. Certain vegetable oils also provide fat-accompanying compounds such as tocopherols or phytosterols. Extraction by pressing or solvent extraction influences the composition of the end product.
With edible and vegetable oils, it is important to distinguish the whole oil from individual isolated fatty acids. The fatty acid pattern differs depending on the raw material; pressing, refining and storage can also influence the accompanying substances. An amount stated in milligrams of oil does not yet say how much of a particular omega fatty acid it contains.
Oils consist mainly of triglycerides, i.e. compounds of glycerol with various fatty acids. Depending on the plant, the proportions of linoleic acid, oleic acid or alpha-linolenic acid differ. Accompanying tocopherols and other fat-soluble substances may also be naturally present.
