It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9, and a main product of Δ9-desaturase. [2] It has the formula CH 3 −(CH 2) 7 −CH=CH−(CH 2) 7 ...
A mix of oils other than the aforementioned exceptions may simply be listed as "vegetable oil" in Canada; however, if the food product is a cooking oil, salad oil or table oil, the type of oil must be specified and listing "vegetable oil" as an ingredient is not acceptable.
This compound has attracted attention because it is a major trans fat found in hydrogenated vegetable oils, and trans fats have been implicated in heart disease. [1] It is the trans isomer of oleic acid. The name of the elaidinization reaction comes from elaidic acid. Its name comes from the Ancient Greek word ἔλαιον (elaion), meaning oil.
Linoleic acid has 18 carbons, is contained in many vegetable oils, particularly semi-drying oils, and is a cis-9-cis-12-di-unsaturated fatty acid. C 17 H 31 CO 2 H, IUPAC organization name (9Z, 12Z)-octadeca-9,12-dienoic acid, numerical representation 18:2 (9,12), n-6, molecular weight 280.45, melting point −5 °C, specific gravity 0.902. CAS ...
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [2] It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm 3. [3]
The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal , vegetable , or petrochemical in origin, and may be volatile or non-volatile. [ 1 ]
A number of oils are used for biofuel (biodiesel and Straight Vegetable Oil) in addition to having other uses. Other oils are used only as biofuel. [note 4] [147] Although diesel engines were invented, in part, with vegetable oil in mind, [148] diesel fuel is almost exclusively petroleum-based. Vegetable oils are evaluated for use as a biofuel ...
α-Linolenic acid, also known as alpha-linolenic acid (ALA) (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid.ALA is found in many seeds and oils, including flaxseed, walnuts, chia, hemp, and many common vegetable oils.
