Canola oil: a healthy vegetable oil
Canola oil is obtained from olive oil, sunflower oil or coconut oil from plant products, and counts therefore to the group of vegetable oils. It is rich in unsaturated fatty acids, and also has a particularly favorable ratio of Omega-3 to Omega – 6 fatty acids. Therefore, rapeseed oil is considered to be extremely healthy. In the kitchen, it can be used both for Frying as well as baking.
Rapeseed oil – a vegetable oil
Rapeseed oil is mainly produced from rape seeds. However, only a small part of the seed is used for the production of edible oil. The far greater part is needed for the production of biofuels. The rapeseed to vegetable oil fuel will be processed much more likely, however, to Biodiesel.
In addition to biofuels, rapeseed oil is included but in many other products, Among other things, it’s in plant protection products, feed products, Motor and lubricating oils, solvents, and in paints and varnishes. In addition, it is used in the medical industry for the manufacture of ointments.
Refined and cold pressed Oil
Rapeseed oil can be obtained by two different methods: hot pressing (refining), and on the other by cold pressing. For the production of the Oil, only the yellow seeds of the fruit are used. The black shell is removed so that no bitter substances can get into the Oil.
Cold-pressed rapeseed oil compared to refined varieties, the advantage that it contains more vitamins, carotenoids and other fat-accompanying substances. This fat-soluble substances that prevent the formation of harmful fat reduction products, by inhibiting the Oxidation of unsaturated fatty acids.
Is canola oil healthy?
Originally, rapeseed oil was used only for technical purposes. Only after oilseed rape varieties have been bred with a lesser bitter substance content, could be used the Oil for the production of edible oils and edible fats.
We now know that rapeseed oil is nutritionally valuable, since it possesses a lot of unsaturated fatty acids and little cholesterol. In this point, the vegetable Oil differs from animal fats such as Butter. These usually contain many saturated fatty acids and less cholesterol.
In addition to unsaturated fatty acids is rapeseed oil tinoiden also rich in Vitamin E and diamonds. Vitamin E is an important free radical scavenger that protects our cells from damage by free radicals. Also carotenoids act in the body as antioxidants and intercept free radicals. Thus, aging processes slow down and can cardiovascular disease be prevented.
Unsaturated fatty acids are valuable
Rapeseed oil consists of 50 to 60 per cent monounsaturated and 25 to 30 percent from polyunsaturated fatty acids. Thus, it provides less monounsaturated fatty acids than olive oil, contains a higher percentage of polyunsaturated fatty acids. Saturated fatty acids are in canola oil, in contrast to animal fat – hardly contain.
Unsaturated fatty acids are for the human body is very important: they reduce the level of unfavorable LDL cholesterol in the blood and have a positive effect on our cardiovascular System. Some polyunsaturated fatty acids are essential for the body, which means he can not produce itself, but you must take in through food.
Omega-3 and Omega-6 fatty acids
To include the essential polyunsaturated fatty acids Omega-3 and Omega-6 fatty acids. For us humans, especially the ratio in which the two fatty acids are to each other is critical. Because we take in too many Omega-6 fatty acids, can have a negative impact on cholesterol levels. A ratio of 2:1 of Omega-6 to Omega-3 fatty acids – such as it is present in the rapeseed oil is ideal.
The distribution of the fatty acids in cold-pressed as well as in refined rapeseed oil. So much of the daily requirement of Omega-3 fatty acids with a tablespoon of the Oil already on the ceilings. In addition, fish species such as mackerel, salmon or herring are good Omega-3-fatty-acid-suppliers. Therefore, fish should, if possible, once or twice a week on the dining plan.
Canola oil for Frying and baking
Canola oil is recommended because of its valuable ingredients for use in the kitchen. Depending on the purpose, you can grab either cold-pressed or refined Oil. For baking and Roasting, more refined rapeseed oil is used because it has almost no taste of its own and is very heat stable.
Cold-pressed rapeseed oil is better for the preparation of salads or Dips – provided you like the distinctive, nutty-saatigen own taste of the Oil.
The Heat-pressed rapeseed oil is cold, however, is less suitable, since the Oil contained in the poly-saturated fatty acids can be decomposed. These are due to their double bonds sensitive to oxygen and high temperatures. By the decomposition of the Omega-3 and Omega – 6 fatty acids not only lose its healthy effects, there is also the risk of the emergence of potentially harmful TRANS is fatty acids.
Rapeseed oil has a relatively long shelf life, according to the dawn, you can use it usually for several months. In order to extend the shelf life, you should store the Oil as dark as possible and cool.
