Critics of canola oil are quick to point out that it is derived from rapeseed, many species of which contain high levels of erucic acid, a substance that in large amounts can be toxic to humans, according to Mayo Clinic nutritionist Katherine Zeratsky, a registered and licensed dietician 1. Erucamide is a primary fatty amide resulting from the formal condensation of the carboxy group of erucic acid with ammonia. Katherine Zeratsky, R.D., L.D. The erucic acid may then be subjected to several processes to produce derivatives such as erucamide, behenic acid, erucate esters, erucyl alcohol, and a C13 dicarboxylic acid commonly referred to as brassylic acid. It is commonly used as a slip additive in the plastic manufacturing industry. But canola has been specifically bred to be very low in erucic acid. Rapeseed oil contains very high levels of erucic acid, a compound that in large amounts can be toxic to humans. It is known as monounsaturated because it has only one double-bonded carbon atom in its fatty acid chain. Canola oil is also low in saturated fat and has a high proportion of monounsaturated fat, which makes it a healthy and safe choice when it comes to cooking oils. Is canola oil “toxic,” as many people warn? The major industrial use of erucic acid is as its primary derivative, erucamide. With . It derives from an Medicinal uses for erucic acid. The toxicity of FFAs to human EndoC-βH1 beta-cells was dampened in mixtures of FFA compositions with a significant content of medium-chain FFAs, but not with a significant proportion of unsaturated FFAs. No. Erucic Acid. Erucic acid is a monounsaturated omega-9 fatty acid. Sulfur-Containing Compounds . Canola oil, however, contains very low levels of erucic acid. The confusion involves erucic acid, a substance in traditional rapeseed that has been linked with structural changes in heart tissues and other problems in animals. A composition with 50% of the very long-chain unsaturated FFA erucic acid caused high toxicity with concomitant peroxisomal H 2 O 2 production. Because of the dangers that may come from ingesting or cooking with these plant oils, wellness experts recommend purchasing plant oils rich in erucic acid for massage or therapeutic purposes. Canola oil contains less than 5% erucic acid (Burrows and Tyrl, 2013). This is known as the n-9 position. Canola meal, which is high in protein, has a variable erucic acid content depending on the method of extraction (Woyengo et al., 2011). The term omega-9 refers to a group of fatty acids, including erucic and oleic acid, which have their double carbon bond occurring at the ninth position from the end of their acid chains. Jojoba contains a chemical called erucic acid, ... Gonzalez A. Erucic acid has been associated with cardiac injury in cattle and experimental rodents (Burrows and Tyrl, 2013).
