Chemical Information
FooDB NameEicosanoic acid
DescriptionArachidic acid, also known as eicosanoic acid, is a saturated fatty acid with a 20-carbon chain. It belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Arachidic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. It is a white crystalline solid. Arachidic acid’s name derives from the Latin arachis—peanut. It can be formed by the hydrogenation of arachidonic acid. Arachidic acid is a minor constituent of cupuaçu butter (7%), perilla oil (0–1%), peanut oil (1.1–1.7%), corn oil (3%), Arabica coffee oil and cocoa butter (1%). It also constitutes 7.1% of the fats from the durian fruit. Arachidic acid is also found in cannabis (PMID:6991645). Arachidic acid occurs naturally in fish and vegetable oils. The salts and esters of arachidic acid are known as arachidates. Diets rich in saturated fats like arachidic acid are associated with increased levels of serum low density lipoproteins. In a study of arachidic acid on Arabica coffee oil (PMID: 29995918), the influence of high-temperature heating on composition and thermo-oxidative stability was studied. The investigated samples showed a stability to oxidation up to approx. 276.8 ̊C -278.3 ̊C and the heat treatment of the beans during the roasting process did not significantly affect the composition in fatty acids. Arabica coffee oil may be used in processes which require high-temperature heating, such as those employed by the food industry, or in the production of pastries. Arachidic acid is also used for the production of detergents, photographic materials and lubricants.
