When we have to classify edible vegetable oils especially those that we are focusing on are vegetable oils, we have to differentiate between two very important types, these are:
- Virgin oils
- Refined Oils
Virgins: Through the extraction process that does not exceed 27 ºC called Cold Press, these types of oils are extracted, which benefits the conservation of both the flavor of the seed or fruit that originates its source of raw material.
Refined Oils: Through centrifugation at a speed of 3200 RPM and filtration through cold extraction, not exceeding 27 ºC. To complete this process, what is done during 1 month and ten days is decanting to filter the finest waste.
By means of these methods the standard bearer can be obtained inside the vegetable oils that is the virgin olive oil.
The process by which it is subjected is refined and also deodorized, with which this allows a neutral taste to be obtained and a clearer color to be seen, ensuring its intake in the food, and duration in a container.
Generally, through this refinement what is achieved is to transform oils that are not suitable for human consumption.
Virgin Olive Oil
It has a very intense flavor considering that you can get the olive from your tree, and with an acidity that ranges between 0.1º and 1.5º.
Its liquid is golden but at the same time translucent, at times it can be greenish in color.
It is a functional food since it is considered to be good for avoiding breast cancer since it has phenolic components and excellent bioactive properties.
Other oils to highlight that you can get in a dietetic or naturist store, as well as in the same supermarket in your neighborhood, is the Sunflower Oil (the vast majority is refined oil), Argan Oil and the classic Olive Oil in its different versions and qualities.
Then we have in more specialized stores, among the most commercialized:
- Pumpkin Oil
- Colza oil
- Safflower Oil
- Grape Nuggets Oil
- Soy oil
Oils derived from nuts:
- Almond oil
- Hazelnut oil
- Walnut Oil
There are other types of oils, both seeds and nuts, as raw material, but these are the ones that stand out the most due to their demand.
The Best: Omega 3 of Marine Origin
A clarification must be done when distinguishing between the two mentioned below:
- Omega 3 of marine origin
- Omega 3 of terrestrial origin
The Omega 3 of marine origin is the one that has greater benefits when it comes to consumption as it can:
- Decrease triglycerides
- Decrease blood cholesterol
Therefore, it is considered a functional food as it directly benefits cardiovascular health.
The oil is not a functional food since it cannot be consumed directly but what is consumed are the polyunsaturated acids that are what have the food for living beings.
