Hello Hermina's Friends! Olive oil is among the most widely utilized cooking oils, particularly in Mediterranean countries. It is extracted from olives, or Olea europaea. Olive oil is widely known for its health benefits. However, do you know whether olive oil is suitable for frying or not? So let’s dive a little deeper into olive oil and the things you need to know.

Definition of Olive Oil

Olive oil is a vegetable oil produced from the grinding of olives. Olives are then pressed and the oil is extracted from the flesh, which is turned into different forms of olive oil. Olive oil has been used as a food component for thousands of years, and also in traditional medicine and cosmetics.

Types of Olive Oil

Hermina’s Friends, there are various types of olive oil, including:

1. Extra Virgin Olive Oil (EVOO)

   EVOO is the highest quality type of olive oil. This is because it is produced with the first phase of olive processing, which does not use any chemicals. EVOO has a distinctive flavor and aroma and is rich in antioxidants.

2. Virgin Olive Oil

   This is also from the first press but is lower quality than EVOO. Virgin olive oil has a wonderful taste and aroma.

3. Refined Olive Oil

   This oil is made from olive oil that has been further processed to remove strong flavors and aromas. In fact, this process decreases their nutritional value instead of increasing it.

4. Olive Pomace Oil

   This is oil made from the leftovers of olive processing. Its quality is lower and is usually used for cooking at high temperatures.

5. Pure Olive Oil

   This is a mixture of virgin olive oil and refined olive oil. Although it is not as good as EVOO in terms of taste and nutrition, pure olive oil can still be used for cooking.

6. Light Olive Oil

   The term "light" in this instance describes a lighter flavor and aroma, not an oil with fewer calories. Light olive oil, which has been processed to lessen its flavor and aroma, is appropriate for recipes that don't want the olive flavor to dominate.

Nutritional Content of Olive Oil

Olive oil is rich in monounsaturated fats, especially oleic acid, which has many health benefits. Furthermore, olive oil contains a variety of antioxidants, including polyphenols, as well as vitamins E and K. The nutritional values of each type of olive oil are as follows:

• Extra Virgin Olive Oil

  Contains about 73% oleic acid, 11% linoleic acid, and 10% palmitic acid. It is also rich in antioxidants and has anti-inflammatory effects.

• Virgin Olive Oil

  Its nutritional content is similar to EVOO, but slightly lower in antioxidants.

• Refined Olive Oil

  Has the same fat content but is lower in vitamins and antioxidants due to the refining process.

• Olive Pomace Oil

  Its nutritional content is lower compared to other types, but it still contains unsaturated fats.

• Pure Olive Oil

  Contains similar fat content as virgin olive oil but with less antioxidants.

• Light Olive Oil

  Its fat content is similar to other types of olive oil but lower in taste and aroma.

Cooking Tips with Olive Oil

The smoke point of olive oil depends on what type it is. The smoke point of EVOO is between 190 and 220°C, while refined olive oil can reach 230°C. Here are some tips for using olive oil:

• The Right Type for Frying

  Because of its higher smoke point, refined olive oil is better suited for frying. On the other hand, EVOO works best as a salad dressing or when sautéing.

• Maximum Temperature

  Avoid cooking with EVOO at extremely high temperatures, as it can damage the nutrients and produce harmful compounds. However, the USDA recommends olive oil as a safe frying option, because it retains many healthy compounds even when heated to high temperatures.

• Reuse

  Olive oil should not be reused for frying, as it can alter its chemical composition and diminish health benefits.

Tips for Buying and Choosing Olive Oil

Hermina’s Friends, when buying olive oil, pay attention to the following points:

• Label

  Choose olive oil that states "extra virgin" for the best quality. However, the best quality comes with an exclusive price.

• Packaging

  Olive oil should be stored in dark bottles to protect it from light that can damage the quality of the oil itself.

• Expiration Date

  Check the expiration date and pick the freshest one. Most olive oil typically has a shelf life of about 18-24 months after production.

Alternatives to Olive Oil at an Economical Price

If olive oil feels too expensive, there are several more affordable oil alternatives, such as:

• Palm Oil

  It has a high smoke point and is suitable for frying. However, it should be noted that palm oil contains higher saturated fats.

• Coconut Oil

  It also has a high smoke point, and can be used for various types of cooking. Coconut oil contains saturated fats but also has certain health benefits.

• Canola Oil

  Almost identical in monounsaturated fat content to olive oil. But olive oil is 75% monounsaturated fat compared to 61% in canola oil. Olive oil consists of 10% polyunsaturated fat, while canola oil has 32%. Olive oil: 15% saturated fat; canola: 7% saturated fat.

• Corn Oil

  Corn oil is another inexpensive alternative that works well for frying and other cooking techniques. It also has a high smoke point.

Conclusion

Olive oil, of course, is a nutritious and healthful choice but in terms of frying, its use requires consideration.Selecting the right oil and learning how to cook with it will ensure that you reap the health benefits of olive oil. Palm oil, coconut oil, canola oil, and corn oil can be cheaper alternatives. If you know what to do, cooking or frying with olive oil or other alternatives can be done wisely.
