1. What is frying process? Which is the best oil for frying?
Frying is a culinary process that consists of introducing a food into an immersion of oil or fat at high temperatures. It is recommended that the temperature of the oil or fat should never exceed 180ºC to conserve the properties of the food. The result of good frying is a food product with a crispy crust. At the same time, the inside remains tender, warm and tasty.
In summary, this is the process of how a food is fried, when it is done well:
- Firstly, during the frying process, there is a rapid formation of a superficial crust on the food, which prevents the infiltration of the oil inside into the food. In this way, an interface is created between the oil and the food, ensuring that the temperature inside remains constant and practically around 100 °C. When the water reaches this temperature, it reaches its boiling point, evaporating and keeping the temperature constant.
- Once the product has been cooked and taken its golden colour, you should remove it from the fire. If we leave it any longer, the food can burn. Because, once the food has completely evaporated its internal water, the crust overheats, suffering the risk of burning its outside. Charred and burnt foods are no healthy, they can produce cancer.
- Therefore, if the food is properly fried and not left to burn, frying does not cause thermal damage to the product. The culinary techniques of frying are more beneficial than other cooking techniques according to science.
a) The importance of good frying oil
Finally, we must take into account that the oil in the frying process also deteriorates with time and use. In other words, the oil degrades also and forms harmful substances for the health. This happens quickly if the oil is used a lot, if it is exposed to high temperatures (when it starts to smoke) and if it is cooked for many hours. Cases that sometimes occur in large industries and restaurants.

3. Best frying oil
According to the latest research, the oil that is capable of maintaining its stability for the longest time, without producing alterations and forming toxic compounds, is extra virgin olive oil. In contrast, the first to degrade in frying are the seed oils.
This is because extra virgin olive oil, due to its high composition in oleic fatty acids (monounsaturated) and its high content in antioxidant compounds. For these reasons, thi oil is the most stable at high temperatures. The University of Granada has also demonstrated that when frying vegetables with extra virgin olive oil, a transfer of polyphenols from the extra virgin olive oil to the food is produced.
However, seed oils are rich in polyunsaturated fatty acids and very low in antioxidants, which deteriorate easily at high temperatures.
a) The Cornicabra and Picual variety
Therefore, extra virgin olive oil is the most stable for making healthy and tasty fried food. Among all the varieties, we always recommend the picual and the cornicabra, which are the best for frying . Also, these could be reused up to 10 times, as long as they are properly filtered to remove the remains of the last fried food and then stored well.
The other varieties of olive oil can also be used, but they cannot be reused so many times. However, many more times than other types of oil, including olive oil, a refined oil with no antioxidants.
Finally, what we do not recommend is to use so-called special oils for frying or from seeds. They are much less stable and deteriorate quickly at high temperatures, with the exception of the high oleic sunflower, that is high in monounsaturated fats.
3. The 7 recommendations for deep frying
Furthermore, we give you some recommendations for getting delicious flavorful and crunchy coating.
- Always use a high-quality extra virgin olive oil of the newest harvest
- The temperature for frying, depending on the need of the food, must be between 150 and 180 °C. Never olive oil can arrive to smoke point, when it starts to smoke.
Also, it is a good idea to stir the hot oil with a wooden spoon to homogenise the temperature of the oil. - The container used for frying should have a large bottom, to allow heat circulation by convention. This way, the hottest oil that is in contact with the bottom rises and when it rises, it cools down and falls again, allowing the heat to be homogenised. Consequently, the heat does not concentrate on one surface of the container and the oil is not burnt.
- Do not mix used oil with new oil to increase the volume of the pan.
- Do not use old oils that are not for preferential consumption. Old oils or oils that are out for consumption should not be used for frying either, as these oils are already deteriorated. Putting them in at high temperatures will increase the oxidised compounds and therefore damage our health.
- Filter the used oil and store it in a jar or grease container to protect it from contact with air and humidity. In this way, we will prevent the oil from oxidising and forming trans acids.

4. Fryer oil brands
There are thousands of brands of extra virgin olive oil of the picual and cornicabra variety on the market. However, what is important is to use a good quality extra virgin olive oil of the year. Therefore, buying an olive oil from any cooperative or oil mill would be a good option. They always produces high-quality extra virgin olive oil.
The oils you can buy in many stores. Here in our shop in Las Rozas de Madrid we offer for sale high-quality olive oil for frying from picual and crnicabra variety. We recommend our San Benito extra virgin olive oil, a olive oil for everyday and every use. An olive oil of the picual variety from Jaen.
Finally, olive oils from large surfaces are usually mixed with very low quality olive oils. They do this because they seek to lower the price of the oil. As a consequence, we do not recommend these oils for frying.

5. Special frying oil, sunflower oil and coconut oil
If you use wetra virgin olive oil for the first fry, it will leave a taste in the product that are you frying. However, oils that are specially sold for frying, sunflower and coconut oil, leave less flavour in the product. Moreover, these oils are made up of unsaturated fatty acids and have hardly any antioxidants, so they can withstand temperatures much worse. This means that they deteriorate more quickly and as a consequence, they form toxic products for the organism.
Large food chains and restaurants that are looking for taste, without caring about the quality and health of the customers, use these types of oil. In addition, many of these places, refuse in excess these oils, making them even more harmful to health.
In short, extra virgin olive oil is the most suitable for frying. Among all the varieties, the picual and cornicabra, are the ones that can best withstand high temperatures.
Furthermore, let’s see different alternatives and its smoking point temperatures. Temperatures thah can not been overtaken.

6. Air fryers
The use of frying in Mediterranean cuisine is very common, giving foods a delicious taste. The downside to this culinary technique is the increase in calories it adds to the product. For this reason, they are under scrutiny by many people, especially those looking to lose weight.
With the aim of meeting the need to continue enjoying fried foods without ingesting high-calorie foods, air fryer technology has been developed. These appliances use air as a source of heat, which is used to cook the food. According to commercial sources, this technology reduces oil usage in frying by up to 90%.
We believe that the qualities of the food will be maintained whether frying with oil or using this type of technology. However, it will depend a lot on the temperatures used, and in the case of frying with oil, the type of oil used. Because if we use extra virgin olive oil, it will give properties to the product, as this is the best oil for frying.
