Rapeseed oil obtained as an experiment. Buryatia, Russia Rapeseed oil is one of the oldest known vegetable oils. There are both edible and industrial forms produced from rapeseed, the seed of several cultivars of the plant family Brassicaceae. Historically, it was restricted as a food oil due to its content of erucic acid, which in laboratory studies was shown to be damaging to the cardiac muscle of laboratory animals in high quantities and which imparts a bitter taste, and glucosinolates, which made it less nutritious in animal feed. Rapeseed oil from standard cultivars can contain up to 54% erucic acid. Canola oil is a food-grade version developed in Canada (hence the name, see below) derived from rapeseed cultivars specifically bred for low erucic acid content. Also known as low erucic acid rapeseed (LEAR) oil, it has been generally recognized as safe by the United States Food and Drug Administration. Canola oil is limited by government regulation to a maximum of 2% erucic acid by weight in the US, and the EU, with special regulations for infant food. These low levels of erucic acid do not cause harm in humans. In commerce, non-food varieties are typically called colza oil. Rapeseed is extensively cultivated in Canada, France, Belgium, Ireland, the United Kingdom, the United States, the Netherlands, Germany, Denmark, and Poland. In France and Denmark, especially, the extraction of the oil is an important industry. History The name for rapeseed comes from the Latin word rapum meaning turnip. Turnip, rutabaga (swede), cabbage, Brussels sprouts, and mustard are related to rapeseed. Rapeseed belongs to the genus Brassica. Brassica oilseed varieties are some of the oldest plants cultivated by humanity, with documentation of its use in India 4,000 years ago, and use in China and Japan 2,000 years ago.: 55 Its use in Northern Europe for oil lamps is documented to the 13th century. Rapeseed oil extracts were first put on the market in 1956–1957 as food products, but these suffered from several unacceptable characteristics. Rapeseed oil had a distinctive taste and a greenish colour, due to the presence of chlorophyll. It also contained a high concentration of erucic acid. Canola was bred from rapeseed cultivar
Is Canola Oil Good for You, or Bad?
Canola oil is a vegetable-based oil found in countless foods. Many people have cut canola oil out of their diet due to concerns over its health effects and production methods.You may still wonder whether it’s best to use or avoid canola oil. This article tells you whether canola oil is good or bad for you. Canola (Brassica napus L.) is an oilseed crop that was created in Canada through crossbreeding of the rapeseed plant. The name “canola” comes from “Canada” and “ola,” denoting oil.Ever since the canola plant was created, plant breeders have developed many varieties that improved seed quality and led to a boom in canola oil manufacturing.Most canola crops are genetically modified (GMO) to improve oil quality and increase plant tolerance to herbicides (1, 2). In fact, over 90% of the canola crops grown in the United States are genetically modified for herbicide resistance, according to an older 2011 study (3). Canola crops are used to create canola oil and canola meal, which is commonly used as animal feed. Canola oil can also be used as a fuel alternative to diesel and a component of items made with plasticizers, such as tires. How is it made?There are many steps in the canola oil manufacturing process.According to the Canola Council of Canada, this process involves the following steps (4):Seed cleaning. Canola seeds are separated and cleaned to remove impurities such as plant stalks and dirt.Seed conditioning and flaking: Seeds are pre-heated to about 95℉ (35℃), then “flaked” by roller mills to rupture the cell wall of the seed.Seed cooking. The seed flakes are cooked by a series of steam-heated cookers. Typically, this heating process lasts 15–20 minutes at 176–221℉ (80°–105°C).Pressing. Next, the cooked canola seed flakes are pressed in a series of screw presses or expellers. This action removes 50–60% of the oil from the flakes, leaving the rest to be extracted by other means.Solvent extraction. The remaining seed flakes, containing 18–20% oil, are further broken down using a chemical called hexane to obtain the remainder of the oil.Desolventizing. The hexane is then stripped from the canola meal by heating it a third time at 203–239℉ (95–115°C) through steam exposure.Processing the oil. The extracted oil is refined by varying methods, such as steam distillation, exposure to phosphoric acid, and filtration through acid-activated clays.In addition, canola oil made into margarine and shortening goes through hydrogenation, a further process in which molecules of hydrogen are pumped into the oil to change its chemical structure.This process makes the oil solid at room temperature and extends shelf life but also creates trans fats. Most of the trans fats that people eat today come from partially hydrogenated oils. A smaller proportion comes from “natural” trans fats found in foods like dairy and meat products (5, 6). Overall, this has meant an increase in the amount of trans fats being consumed. “Industrial” trans fats created through oil processin.
Canola Oil Cooking Benefits.
Medically Reviewed by Christine Mikstas, RD, LD on August 31, 2022 Canola oil is oil made from crushed canola seeds. One of the best oils for heart health, canola oil has less saturated fat than any other oil commonly used in the U.S. Cutting down on saturated fats helps cut your cholesterol levels.Canola oil is also very high in healthier unsaturated fats. It’s higher in the omega-3 fatty acid alpha-linolenic acid (ALA) than any other oil except flaxseed oil. ALA is particularly important to have in your diet because your body can’t make it.Studies show that ALA may help protect the heart through its effects on blood pressure, cholesterol, and inflammation. The FDA allows canola oil makers to label their products with a qualified health claim that there’s “limited and not conclusive” scientific evidence that switching out saturated fat for the same amount of canola oil may reduce risk of heart disease.Because of its light flavor, high smoke point, and smooth texture, canola oil is one of the most versatile cooking oils. You can use it in a number of dishes and cooking methods, like:As a cooking oil for sauteing, stir-frying, grilling, and bakingIn salad dressings, sauces, and marinadesTo coat your pans for nonstick bakingInstead of solid fats (such as margarine and butter) in recipesBecause canola oil is rich in omega-6 fats which are common in many foods, it can add to the amount of omega-6 in your diet compared to the amount of omega-3. Some studies show that a high ratio of omega-6 to omega-3 can raise your risk of certain diseases and conditions, such as Alzheimer’s, obesity, and heart disease.Canola oil is also highly refined. This means it goes through a process that uses heat and chemicals to extract the oil. This can reduce the amount of nutrients it has to offer. 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. But, in fact, it’s levels of erucic acid are well below the FDA’s standards.In addition to canola oil’s hearty helping of omega-3 fats (9%-11%), it’s also very high in monounsaturated fat (63%), a healthy fat. Another bonus: Canola oil contains phytosterols, molecules that reduce the absorption of cholesterol in your body. When it comes to saturated fat, canola oil is lowest compared to other oils:Canola oil is 7% saturated fatSunflower oil is 9% saturated fatCorn oil is 13% saturated fatOlive oil is 14% saturated fatIf you’re unsure about canola oil, there are other options you can try instead. When you’re cooking with heat, consider:Coconut oilOlive oilAvocado oilFor recipes that don’t involve heat, such as salad dressings, try:Flaxseed oilWalnut oilHemp seed oil NUMBER:4 URL: https://www.medicalnewstoday.com/articles/canola TITLE: Canola oil: Benefits, risks, and alternatives CONTENT: Canola oil is a vegetable-based oil used in various foods and products. It may provide health benefits, but some people have concerns about its properties and production methods.There are many oils that people can use for cooking, and canola oil is a popular option. Nevertheless, misconceptions about the benefits and risks of canola oil exist. Like other oils, canola oil contains many different fats and may provide some health benefits.This article looks at canola oil and its manufacturing process. It also outlines the nutritional information, health benefits, and potential risks and explores some alternative oils.Canola, or Brassica napus, is one of the most important oilseed crops globally. The name “canola” comes from the words “Canada” and “ola,” meaning oil.Scientists in Canada created canola through crossbreeding an edible type of rapeseed plant. By crossbreeding, they removed toxic compounds called glucosinolates and erucic acid.The canola plant looks identical to the rapeseed plant, but it contains different nutrients, and its oil is safe for consumption.Since scientists created the canola plant, breeders have developed different varieties with improved seed quality. This has led to a massive increase in canola oil manufacturing.Most canola crops are genetically modified (GM), which improves the quality of the oil and increases the plant’s tolerance to herbicides. GM canola makes up 95% of canola planted in the United States.According to the Canola Council of Canada, the process for turning canola seed into oil is similar to that of other oilseeds. CleaningThe process begins with cleaning the canola seeds thoroughly to remove stems, pods, weed seeds, and other materials that are present from harvesting.Heating and flakingMachines then heat and flake the canola seeds before extracting the oil. They raise the temperature slightly in grain dryers to prevent the seed from shattering. They then pass the seeds through rollers to rupture the cell walls and flake the seeds to the ideal thickness.CookingThe seeds progress through a series of stacked cookers or heating drums. This process further ruptures the cells and obtains the correct viscosity and moisture level that the upcoming steps require. Cooking also prevents the product from breaking down, which could affect its quality.PressingThe heated flakes then progress through a series of expellers or pressers for gentle pressing. This process removes most of the oil and compresses the remaining seed into a solid cake.ExtractionAn extractor then removes the remaining oil from the pressed cakes with a solvent called hexane. The machine then separates the oil and solids and recycles the hexane for further use.Refining and processingProcesses refine the crude oil to improve its flavor, color, and shelf-life. Water and organic acids remove gums, fatty acids, fine meal particles, and lipids. A process called bleaching removes color pigments, though it does not use bleach.
canola oil is a type of vegetable oil derived from rapeseed and has been developed to be safer for consumption by selectively breeding cultivars with low erucic acid content. It is considered a heart-healthy oil due to its low saturated fat content and high levels of unsaturated fats, particularly ALA. Canola oil is widely used in cooking and food products, but individuals may choose alternatives based on their dietary preferences and health considerations.
