One suitable oil that can be used for deep frying is sunflower oil. It is recommended that oils with a high smoke point be used when frying food.
The smoke point of an oil is defined as the temperature at which the oil begins to omit smoke. Therefore, oils with a higher smoke point can be heated to higher temperatures without producing smoke and fumes.
Another good type of oil that can be used for deep frying is palm oil. Additionally, avocado, almond, and hazelnut oil can be used. A refined or light olive oil is suited for deep frying as well.
