Medicinal uses for 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. But, as current myths demonstrate, the negative connotations associated with rapeseed's name persisted. The erucic acid content of commercially available canola oil averages 0.6 percent. This is temporary and reversible. Canola oil, however, contains very low levels of erucic acid. The total amount of omega-3 fatty acids in the oil is approximately 39% (with 38% alpha-linolenic acid). Erucic acid is produced by elongation of oleic acid via oleoyl-coenzyme A and malonyl-CoA. 2009 Nov 16;2(4):337-47. But canola has been specifically bred to be very low in erucic acid. This effect is reversible and transient during prolonged exposure. +39 0521 036 149E-mail: Press@efsa.europa.eu, Chemical contaminants, Chemicals in food, Animal health. 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. More Share Options . Otherwise, please use the Ask EFSA Service. Interpretation Translation  erucic acid /əˌrusɪk ˈæsəd/ (say uh.roohsik 'asuhd) noun a solid fatty acid derived from oils of mustard seed and rapeseed. Mustard, Wild, Tender And Tough by DEANE. 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 is produced naturally (together with other fatty acids) across a great range of green plants, but especially so in members of the genus Brassica. Synthesis of azelaic acid and brassylic acid. The use of this oil results in inflammation. EFSA experts said there may be a health risk for poultry but noted that the calculation method used overestimated exposure. evaluation of the toxicity of erucic acid for animals and humans, considering all relevant adverse health effects; 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. So, a name change was in order. 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 heart is the principal target organ for toxic effects after exposure. The trans isomer is known as brassidic acid. human infants have relatively low amounts of this enzyme and because of this, babies should not be given foods high in erucic acid. The total amount of omega-6 fatty acids in camelina oil is approximately 18% (with 17% linoleic acid). Citations Crossref 6 Web of Science 5 Scopus 8. Erucic Acid. It is a very long chain fatty acid that when taken up into the cell membrane interferes in normal function. Chemical Structure The erucic acid is represented by the formula 22: 1 ω-9. Varieties low in erucic acid and glucosinolates (the so-called double low cultivars) were developed using classic plant breeding techniques. EFSA Media Relations OfficeTel. Erucic acid, a fatty acid, occurs naturally in animal, fish and vegetable fats. To address information gaps, the Panel recommended further data collection on erucic acid concentrations in processed foods such as fine bakery wares and food for infants and small children. Myocardial lipidosis was identified as the critical effect for chronic exposure to erucic acid. It is a bizarre fatty acid compound (monounsaturated omega-9 fatty acid), which is known to be highly toxic in nature. Canola oil consists of erucic acid that can impact the heart. Food-grade rapeseed oil (also known as canola oil, rapeseed 00 oil, low erucic acid rapeseed oil, LEAR oil, and rapeseed canola-equivalent oil) is regulated to a maximum of 2% erucic acid by weight in the USA[9] and 5% in the EU,[10] with special regulations for infant food. Jojoba contains a chemical called erucic acid, which can cause serious side effects such as heart damage. Erucic acid appears as a glycerol ester in seed fats. The dietary exposure assessment has concluded that the majority of exposure to erucic acid by the general population would come from the consumption of colza oil. Erucic acid's production and use as a chemical intermediate may result in its release to the environment through various waste streams. Monounsaturated omega-9 fatty acid, denoted 22:1ω9. Because it has been linked to cardiac muscle damage, oils such as canola oil were developed that are low in erucic acid. high consumers, children, people following a specific diet, etc. Format: PDF available for immediate download. The most important from the point of view of animal production are the glucosinolates that reduce feed acceptance due to their ‘hot’ and pungent taste (similar to that in mustard and horseradish). Other potential effects observed in animals – including changes in the weight of the liver, kidney and skeletal muscle – occur at slightly higher doses. 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. Sources of exposure. But canola has been specifically bred to be very low in erucic acid. For infants (0-12 months), infant formulae is the main source. Number of Pages: 4. It is also the Latin for coleworth, which today is better known as kale. Erucic Acid. erucic) Trimis de raduborza, 15.09.2007. In 1956, the FDA banned rapeseed oil because of high amounts of erucic acid, which made it unfit for human consumption. Chapter 14 in Hayes' Principles and Methods of Toxicology, Sixth Edition. Cardiac effect of erucic acid, which is a member of omega-9 fatty acid, is investigated on doxorubicin treatment in this study. [7][9][10], In 2003, Food Standards Australia set a provisional tolerable daily intake (PTDI) for an average adult of about 500 mg/day of erucic acid, extrapolated based on "the level that is associated with increased myocardial lipidosis in nursing pigs. Average consumer exposure ranges from 0.3 to 4.4 mg/kg bw per day across age groups. Most humans would be exposed to erucic acid by the inclusion of these oils in the diet. But among consumers with higher exposure, infants and other children could be exposed to up to 7.4 mg/kg bw per day. Erucic acid is a substance naturally found in some plant-derived oils, primarily in some varieties of mustard seed oil and high erucic acid rapeseed oil. Some Brassica cultivars can have up to 40 to 50 percent of their oil recovered as erucic acid. This effect is reversible and transient during prolonged exposure. 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. Erucamide was a slight skin irritant in rabbits. This enzyme breaks this long chain fatty acid into shorter-chain fatty acids. 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. Myocardial lipidosis was identified as the critical effect for chronic exposure to erucic acid.

Myocardial lipidosis was identified as the critical effect for chronic exposure to erucic acid. [4] Erucic acid is broken down into shorter-chain fatty acids in the human liver by the long-chain acyl CoA dehydrogenase enzyme. 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. The genus includes colewort (E. sativa), which today is better known as arugula (US) or rocket (UK). It has limited ability to polymerize and dry for use in oil paints. The heart is the principal target organ for toxic effects after exposure. It is present in pastries, cakes and infant/follow-on formulae and also in some animal feed (e.g. Erucic acid is a monounsaturated omega-9 fatty acid, denoted 22:1ω9. Hypertension; Canola oil consists of substances that can increase blood pressure. It mainly enters the food chain when rapeseed oil is used in industrial food processing and home cooking in some countries. The heart is the principal target organ for toxic effects after exposure. Several researches have proved that mustard oil contains a huge amount (approximately between 42% and 47%) of erucic acid. This would be particularly so if the level of erucic acid in colza oil were to exceed 2% of the total fatty acids."[7]. Erucic Acid. These factors include glucosinolates (goitrogenic), erucic acid (toxic), tannins, sinapine, phytic acid, and mucilage. 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. Much of it is RoundUp ready - resistant to the toxic Glyphosate. There exist epidemiological evidence that pediatric brain tumor incidence is among the lowest in the Chinese population. Topics similar to or like Erucic acid. The toxicity of erucic acid is virtually always considered in the context of the toxicity of rapeseed and mustard seed oils, which can contain high levels of erucic acid. but canola oi This effect is reversible and transient during prolonged exposure. No. erucic acid [ĕ-roo´sik as´id] a monounsaturated fatty acid that is a major constituent of certain oils, such as rapeseed oil. Erucic acid is broken down into shorter-chain fatty acids in the human liver by the long-chain acyl CoA dehydrogenase enzyme. "[7] "There is a 120-fold safety margin between this level and the level that is associated with increased myocardial lipidosis in nursing pigs. rapeseed meal). 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. Erucic Acid is an omega 9 oil, and certainly has inflammatory properties. {New Latin Eruc(a) the rocket 2 genus + -ic} Australian English dictionary. [7] While there are reports of toxicity from long-term use of Lorenzo's oil (which contains erucic acid and other ingredients), there are no reports of harm to people from dietary consumption of erucic acid. Erucic acid is also known as cis-13-docosenoic acid. Genetic Modification Of Rapeseed. Myocardial lipidoses can be associated with a reduction of the contractile power of the heart muscle. Short-term oral administration to rats did not identify any particular site of toxic action, but no microscopic examination of the tissues was conducted. high consumers, children, people following a specific diet, etc. Erucic acid is a monounsaturated omega-9 fatty acid, which is present in the oil-rich seeds of the Brassicaceae family of plants, particularly rapeseed and mustard. Erucic acid is also known as cis-13-docosenoic acid and the trans isomer is known as brassidic acid. Contains Erucic Acid. No. In 1976 the EU set maximum limits for erucic acid as a contaminant in vegetable oils and fats, and foods containing added vegetable oils and fats as an ingredient. The dietary intake of erucic acid by an individual consuming at the average level is well below the PTDI; therefore, there is no cause for concern in terms of public health and safety. acid erucic = acid nesaturat în gliceride şi în uleiul din seminţele de rapiţă şi de muştar. Studies done on laboratory animals in the early 1970s show that erucic acid appears to have toxic effects on the heart at Date of Publication: 2001. 41b,41c,41d. 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. Intake of … An association between the consumption of rapeseed oil and increase… Is canola oil “toxic,” as many people warn? Other potential effects observed in animals – including changes in the weight of the liver, kidney and skeletal muscle – occur at slightly higher doses. 5.03.2.2.4 Long-chain dicarboxylic acids. However, more recent research has cast doubt on the relevance of rat studies to the human health of erucic acid. 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. InChI=1S/C22H42O2/c1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22(23)24/h9-10H,2-8,11-21H2,1H3,(H,23,24)/b10-9-, InChI=1/C22H42O2/c1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22(23)24/h9-10H,2-8,11-21H2,1H3,(H,23,24)/b10-9-, Except where otherwise noted, data are given for materials in their. The health-damaging effects include myocardial lipidosis (lipid storage dis- ease), which results in abnormal accumulation of lipids (“fatty degeneration”) in the heart tissue. In pigs, feed levels of erucic acid are unlikely to represent a health concern. The new name "canola" is a conjunction of "Canada oil low acid," which aptly describes the location and … Myocardial lipidosis was identified as the critical effect for chronic exposure to erucic acid. This article reviews rapeseed oil, including its nutritional content, benefits, and potential downsides. Wikipedia. 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. CAS Number*: 112-84-5. Erucic acid has many of the same uses as mineral oils, but it is more readily biodegradable than some. Figure 18. This prompted Canadian growers in the 1970s to breed a new variety of rapeseed with a lower content of the toxic erucic acid. [8]:646–657, Publication of animal studies with erucic acid through the 1970s led to governments worldwide moving away from oils with high levels of erucic acid,[5] and tolerance levels for human exposure to erucic acid have been established based on the animal studies. ; The name erucic means: of or pertaining to eruca; which is a genus of flowering plants in the family Brassicaceae. Varieties low in erucic acid and glucosinolates (the so-called double low cultivars) were developed using classic plant breeding techniques. Omega-9 fatty acids (ω−9 fatty acids or n−9 fatty acids) are a family of unsaturated fatty acids which have in common a final carbon–carbon double bond in the omega−9 position; that is, the ninth bond from the methyl end of the fatty acid. Forty-eight rats were divided into eight groups and each group contained six rats … Effects of erucic acid supplemented feeding on chronic doxorubucin toxicity in rats Int J Clin Exp Med.
