It is a very long chain fatty acid that when taken up into the cell membrane interferes in normal function. 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. And the Authority, in an opinion published this week , found a data gap in relation to available information on the carry-over of erucic acid in meat, milk and eggs resulting from feed use. {New Latin Eruc(a) the rocket 2 genus + -ic} Australian English dictionary. Eds A. Wallace Hayes, Claire L. Kruger. The erucic acid content of commercially available canola oil averages 0.6 percent. Erucic acid is also known as cis-13-docosenoic acid and the trans isomer is known as brassidic acid. Rapeseed oils made from plants which contain a large amount of erucic acid and used to produce oil containing up to 50% erucic acid pose health risks to humans and are not suitable for use in livestock feed. EFSA experts said there may be a health risk for poultry but noted that the calculation method used overestimated exposure. However, more recent research has cast doubt on the relevance of rat studies to the human health of erucic acid. But among consumers with higher exposure, infants and other children could be exposed to up to 7.4 mg/kg bw per day. But canola has been specifically bred to be very low in erucic acid. Erucic Acid. Erucic acid is also known as cis-13-docosenoic acid and the trans isomer is known as brassidic acid. Cutting the Wild Mustard: Brassica & Sinapis Lorenzo’s Oil and Canola, Too.

It is a bizarre fatty acid compound (monounsaturated omega-9 fatty acid), which is known to be highly toxic in nature. Erucic Other potential effects observed in animals – including changes in the weight of the liver, kidney and skeletal muscle – occur at slightly higher doses. In 1956, the FDA banned rapeseed oil because of high amounts of erucic acid, which made it unfit for human consumption. This effect is reversible and … Format: PDF available for immediate download. comprise the (a) evaluation of the toxicity of erucic acid for animals and humans, considering all relevant adverse health effects; (b) estimation of the dietary exposure of the European Union (EU) population to erucic acid including the consumption patterns of specific (vulnerable) groups of the population (e.g. erucic acid. So, a name change was in order. In ‘Infants’, ‘Food for infants and small children’ was the main contributor to exposure. If you are a Journalist/Media representative, please contact our Media Relations Office. Otherwise, please use the Ask EFSA Service. some internet sites claim that canola oil has high levels of erucic acid, a substance that can be toxic to humans and can lead to ailments ranging from respiratory distress to blindness. The health-damaging effects include myocardial lipidosis (lipid storage dis-ease), which results in abnormal accumulation of lipids (“fatty degeneration”) in the heart tissue. This prompted Canadian growers in the 1970s to breed a new variety of rapeseed with a lower content of the toxic erucic acid. Myocardial lipidosis was identified as the critical effect for chronic exposure to erucic acid. Delay Normal Growth; Canola oil should not be used for infants because it may delay normal growth. Rats are unusual in their inability to process erucic acid, and the symptoms in rats caused by a diet with high levels of erucic acid has not been observed in pigs, primates, or any other animals. 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. … ; The name erucic means: of or pertaining to eruca; which is a genus of flowering plants in the family Brassicaceae. Like other fatty acids, it can be converted into surfactants or lubricants, and can be used as a precursor to biodiesel fuel. erucic acid [ĕ-roo´sik as´id] a monounsaturated fatty acid that is a major constituent of certain oils, such as rapeseed oil. To stay in business, Canadian rapeseed oil manufacturers looked for a way to reduce this component through cross-breeding, and the canola crop was born. 2009 Nov 16;2(4):337-47. The health-damaging effects include myocardial lipidosis (lipid storage dis- ease), which results in abnormal accumulation of lipids (“fatty degeneration”) in the heart tissue. Chemical Structure The erucic acid is represented by the formula 22: 1 ω-9. This effect is reversible and transient during prolonged exposure. 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. Mustard, Wild, Tender And Tough by DEANE. Erucic acid, also know as cis–13-docosenoic acid, is an unbranched, monounsaturated fatty acid with a 22–carbon chain length and a single double bond in the omega 9 position. Maximum levels have been established for erucic acid in vegetable oils and fats, in foods containing added vegetable oils and fats and in infant formulae and follow-on formulae by Commission Regulation (EC) No 1881/2006 of 19 December 2006 setting maximum levels for certain contaminants in foodstuffs. Erucic Acid. New toxicity studies could also improve understanding on the effects for humans and animals, particularly for target livestock animals and fish. More Share Options . The heart is the principal target organ for toxic effects after exposure. Somewhere further down the line, it did start finding its way into the food chain, but because it is so toxic, the US Food and Drug Administration (FDA) intervened and officially banned it in 1956, stating that it was unsafe for human consumption due to its high levels of erucic acid. Mustard oil is rich in unsaturated fatty acids, but it also contains a special type of fatty acid called erucic acid, which lies at the center of the controversy surrounding the oil. It constitutes 30–60% of the total fatty acids of rapeseed, mustard seed and wallflower seed and it represents up to 80% of the fatty … Erucic acid appears as a glycerol ester in seed fats. This would be particularly so if the level of erucic acid in colza oil were to exceed 2% of the total fatty acids."[7]. Food Standards Australia New Zealand (June 2003), Luger CL et al. Myocardial lipidoses can be associated with a reduction of the contractile power of the heart muscle. [6] An association between the consumption of rapeseed oil and increased myocardial lipidosis, or heart disease, has not been established for humans. [4] Erucic acid is broken down into shorter-chain fatty acids in the human liver by the long-chain acyl CoA dehydrogenase enzyme. Erucic acid. Erucamide is apparently hydrolysed to erucic acid, which can produce heart damage on feeding to laboratory animals. [Erucic acid is toxic at least in part because it alters the chemistry of cell membranes; numerous studies show the changes in cell membranes. Monounsaturated omega-9 fatty acid, denoted 22:1ω9. Erucic acid is toxic and causes tissue damage in many organs of laboratory animals. Studies done on laboratory animals in the early 1970s[5] show that erucic acid appears to have toxic effects on the heart at high enough doses. Much of it is RoundUp ready - resistant to the toxic Glyphosate. It has limited ability to polymerize and dry for use in oil paints. Erucic acid (also see Fats) A fatty acid found in large amounts in rape and mustard seed oils, and widely (but mistakenly) thought to be toxic. Short-term oral administration to rats did not identify any particular site of toxic action, but no microscopic examination of the tissues was conducted. Erucic Acid is an omega 9 oil, and certainly has inflammatory properties.

Erucic acid is also known as cis-13-docosenoic acid. Tests on animals show that ingesting oils containing erucic acid over time can lead to a heart condition called myocardial lipidosis. Wikipedia. Is canola oil “toxic,” as many people warn? The name erucic means "of or pertaining to Eruca", which is a genus of flowering plants in the family Brassicaceae. Erucic acid is a monounsaturated omega-9 fatty acid found mainly in the Brassica family of plants such as canola, rapeseed, wallflower seed, mustard seed as well as Brussels spouts and broccoli. Research in animals indicates that, over long periods, erucic acid may cause a heart condition called myocardial lipidosis. Originally, raw rapeseed oil was extremely high in erucic acid, which is potentially toxic and can damage the heart, liver, and kidneys[*]. This in turn alters the normal functioning of the cell, and also the mitochondria (the source of energy for all our cells) which has its own membrane. Objective: One of the ligands of PPAR-δ is erucic acid (EA), an edible omega-9 fatty acid consumed more by Asian populations and exists highly in Chinese womens milk. These substances along with other plant toxins like lectins, phytates, and goitrogens are capable of inhibiting protein digestion by decreasing the secretion of HCL (stomach acid) and protein-digesting enzymes.
