What is olive oil?
History of olive oil
The history of olive oil goes back thousands of years. Its use dates back to ancient Greece and ancient Rome, where it played an important role in both cuisine and medicine. Olive oil was not only used as food, but also as lamp oil, lubricant, and a cosmetic product. Over the centuries, olive oil spread across the world and has become one of the most popular oils today. It is still widely used in Mediterranean cuisine because of its unique flavor and health benefits.
Production of olive oil
The production of olive oil begins with harvesting the olives. This usually takes place in autumn when the olives are ripe. The olives are picked by hand or harvested mechanically. Next, the olives are washed to remove dirt and leaves. They are then crushed into a paste, which is pressed to extract the oil. The oil is filtered to remove any remaining particles and then stored in tanks. Producing high-quality olive oil requires care and craftsmanship.
Classification of olive oil
Olive oil is classified based on its acidity level and production method. The acidity level is determined by the amount of free fatty acids present. Extra virgin olive oil has the lowest acidity, while refined olive oil may have a higher acidity. The method of production also affects classification. Cold-pressed olive oil is obtained through mechanical pressing without heat, while refined olive oil is produced through chemical processes and refining. Understanding olive oil classifications is important because they affect the flavor and quality of the final product.
Extra virgin olive oil
Characteristics of extra virgin olive oil
Extra virgin olive oil is the highest-quality olive oil available. It is obtained from the first cold pressing of the olives without any chemical treatment. This oil has an intense flavor and aroma and is ideal for salads, dressings, and dips. It is also rich in antioxidants and healthy fats, contributing to a nutritious diet. To maintain its quality, extra virgin olive oil should be stored in a cool, dark place. Always choose a reputable brand to ensure top quality.

Virgin olive oil
Difference between extra virgin and virgin olive oil
The main difference between extra virgin and virgin olive oil lies in their acidity and flavor. Extra virgin olive oil is obtained through pressing without chemical treatment and has the lowest acidity and most intense flavor. Virgin olive oil has a slightly higher acidity and a milder flavor. Both are suitable for salads, dressings, and cold dishes, but extra virgin is often used as a finishing oil for warm dishes. It is important not to heat extra virgin olive oil too much, as this can damage its delicate flavor and nutrients.
Quality of virgin olive oil
The quality of virgin olive oil is crucial when choosing and using olive oil. Virgin olive oil is produced through mechanical processes without chemical treatments. There are several classifications, including extra virgin, virgin, and ordinary virgin olive oil. Extra virgin is the highest quality and has very low acidity, often used in salads, dressings, and as a bread dip. Virgin olive oil has a slightly higher acidity and can also be used for baking and sautéing. Ordinary virgin olive oil has an even higher acidity and is mainly used for cooking at higher temperatures.
Uses of virgin olive oil
Virgin olive oil is one of the most commonly used types of olive oil in the kitchen. Obtained from the first pressing without chemical processes, it has a rich flavor and low acidity, making it ideal for dressings, marinades, and sauces. It can also be used for cooking, as it has a relatively high smoke point. It adds wonderful flavor to meals and is a healthy source of fats. In short, virgin olive oil is versatile and a valuable addition to any kitchen.
Refined olive oil
Refining process
The refining process is an important step in the production of olive oil. During refining, impurities and unwanted substances are removed from the raw oil, making it purer and improving its quality. Refining involves several steps including degumming, neutralization, bleaching, and deodorizing. Degumming removes phospholipids and other unwanted substances. Neutralization removes acids and other impurities. Bleaching absorbs pigments and impurities, and deodorizing removes unwanted odors and flavors. Refining ensures the olive oil meets quality standards and is suitable for consumption and various culinary uses.
Uses of refined olive oil
Refined olive oil has many uses both in and outside the kitchen. It is often used for frying, sautéing, and deep-frying because of its high smoke point. It's also a common ingredient in dressings, sauces, and marinades due to its neutral flavor. Outside the kitchen, refined olive oil is used as a natural moisturizer for skin and hair thanks to its hydrating properties.
Advantages and disadvantages of refined olive oil
Refined olive oil has both pros and cons. Its neutral flavor makes it suitable for all kinds of cooking, and its higher smoke point makes it more stable at high temperatures. It also has a longer shelf life than extra virgin olive oil. However, the refining process removes some nutrients such as antioxidants and vitamins, and the flavor is less rich compared to extra virgin. It's best to alternate its use with higher-quality oils.
Olive oil blends
Different types of olive oil blends
There are various olive oil blends used in cooking. A common blend mixes extra virgin olive oil with a small percentage of other oils, such as sunflower or grapeseed oil. This blend combines the flavor and health benefits of extra virgin olive oil with the neutral taste and higher smoke point of the other oils. Blends with herbs or spices also exist and add extra flavor to dishes, making them perfect for salads, pasta, and grilled vegetables.
Uses of olive oil blends
Olive oil blends are used in both cooking and cosmetics. In the kitchen, they are ideal for dressings, marinades, and sauces, as well as for grilling or baking vegetables and meats. In cosmetics, olive oil blends are valued for their hydrating and nourishing properties and are used in skincare products or as natural makeup removers.
Benefits of olive oil blends
Olive oil blends offer several benefits. They can add unique flavor and aroma to dishes, have a higher smoke point than pure olive oils, and often contain a mix of oils that provide a broader range of nutrients and antioxidants.
