It is a delusion which will never go away. Many people have gotten so used to it that many top chefs are repeating the error of believing that Extra Virgin Olive Oil should be used cold and not mixed.
Many dishes can be prepared with extra virgin olive oil. These are just a few reasons.
A Fast Chemistry Lesson
Oils are mostly made up of triglycerides which are fats. These oils contain a variety (hence the "tri") of fatty acid that is attached to a chemical called glycerol.
Oils contain a small amount of free fat acid. This is fatty acids which have not been bonded to glycerol, but are floating on their own. There are many oils with different levels of free-fatty acids. It all depends on the quality and composition of the petroleum jelly.
You have the option to have your oil fatty acids as a part of a saturated or free choice. Monounsaturated fats don't have double bonds, while saturated fats do. However, polyunsaturated oils have many.
Exposure to heat, light, and heat can cause oil damage, especially if oils are subject to prolonged heat or significant heat. It is best to store oil in cool, dark places to ensure freshness. You should be cautious when using oils in your cooking.
Understanding Smoke Points
The smoke point is the temperature at which the oil's bluish smoke rises indefinitely. Extra Virgin Olive Oil is a natural solution that contains very little water.
When oil is heated in a pan, steam will rise from it. This is not a sign that you are causing damage to the petroleum. The risk of oxidative and/or chemical damage to petroleum increases when it is heated beyond its smoke point.
Most polyunsaturated fats with a variety double bonds are more vulnerable and susceptible to damage. Saturated fats without dual bonds are very stable. Monounsaturated fats are less susceptible to oxidative damage.
Oils with high levels free fat acids are more susceptible to oxidative damage. Smoke recommendations are used to decide if an oil type is suitable for cooking. It is important, but it can also be secondary.
You might see Olive Oils as the only option. There are likely to be smoke issues, depending on where they come from. It all depends upon the oil's quality and freshness, as well as its storage conditions and the amount of protective antioxidants.
It is an excellent source of monounsaturated and stable fatty acids.
It has a very small amount of free fatty acids.
It is also rich in antioxidants.
Extra Virgin Olive Oils are often made with smoke issues. They usually range from 190-220degC. The highest quality oils can be found in the higher end of the range, such as Cobb Estate Extra Virgin Olive Oils.
This is how you compare cooking. While sauteing on the stove can be a great way to cook, deep-frying and baking in the oven are much better. It is illegal to cook food at higher temperatures than recommended.
Important to remember that oil and fats with higher nicotine levels have no added benefit. This means that extra virgin olive oils can be used if vegetable roasting temperatures are 180 degrees Celsius. However, it must have a smoke point higher than this. It is safer to select an oil with a smoke point higher than 220°C.
Extra Virgin Olive Oil is a must have
A few exceptions have shown the stability of Extra Virgin Olive Oil when consumed. These scientific reports have opened up the possibility of oil separation. They heat the oils multiple times, so they heat them long enough to bring them to boiling point.
These conditions are nearly impossible to attain in home cooking. Extra-virgin oils are safe to use at home. This holds true even for oils rich with polyunsaturated fats such as sunflower oil and generic vegetable oil.
Research has shown that extra-virgin olive oil can increase antioxidant levels in vegetables. This doubles the value of extra virgin olive oils' excellent fats, and higher availability of protective compounds.
Research supports extra virgin olive oils' role as a healthy, nutritious food. It can be used in nearly every type of cooking and even cold shellfish can benefit from it. It is safe and has many health benefits.
We are doing the same thing that the Mediterranean countries did for hundreds of centuries. Extra virgin olive oils are a favorite ingredient in our cooking.
