Various Olive’s Oils
Olive oil is available in a variety of flavors, colors, and qualities. The primary varieties of olive oil are:
- Extra-Virgin Olive Oil: This is considered to be the highest-quality olive oil and is made from pure, cold-pressed olives. It has a strong, fruity flavor and is typically used in salad dressings, marinades, and dips. To be considered extra-virgin, the oil must meet strict standards for acidity, flavor, and aroma.
- Virgin Olive Oil: This type of oil is also made from pure, cold-pressed olives, but may not meet the stringent requirements for extra-virgin one. It has a slightly less fruity flavor than extra-virgin oil and is suitable for cooking.
- Pure Olive Oil: This type of oil is made by blending virgin olive oil with refined olive’s oil. It has a milder flavor than virgin or extra-virgin oil and is often used in cooking and baking.
- Extra Light Olive Oil: This type of oil is made by blending pure olive oil with a neutral oil such as sunflower oil, which has no strong taste or aroma. The result is a light-tasting olive’s oil that is suitable for high-heat cooking.
- Olive Pomace Oil: This type of oil is made by using the remaining paste after the oil has been extracted, is then treated with solvents and subjected to heat and then filtered. It is less expensive than other types of olive’s oil, but has a milder flavor and is often used in commercial cooking.
How Olive Oil is Produced
Olives, the olive tree’s fruit, are used to make olive oil. There are various steps involved in manufacturing it.
Harvesting and Cleaning: Olives are picked by hand or with the aid of motorized shakers. Since the olives have the most oil content at these stages, they are normally harvested when they are green or purple.
After harvest, the olives are washed and sorted to get rid of any leaves, twigs, or other debris.
Crushing and Separating the Oil: The olives are then crushed to release the oil. This can be done using a traditional stone mill or a modern industrial crusher.
A centrifuge is subsequently used to extract the oil from the remaining mixture. The leftover solids are removed, and the oil is collected.
Filtering and Bottling: After that, the oil is filtered to get rid of any contaminants or sediment. The olive oil must then be bottled and labeled with information about its type and quality. The best olive oil is extra-virgin, which is produced by cold-pressing only pure olives.
It has a strong, fruity flavor and is often used in salads and dips. Virgin olive oil is also made from pure, cold-pressed olives, but may not meet the stringent requirements for extra-virgin olive oil. It has a slightly less fruity flavor and is suitable for cooking.
- How should I store olive oil?
Olive oil should be stored in a cool, dark place, such as a pantry or cupboard, away from heat and light. It should also be stored in a tightly sealed container to prevent it from going rancid. Exposure to air and light can lead to oxidation, which will change the taste and nutritional value of the oil.
- How long does it last?
It has a shelf life of about 18-24 months, but it can last longer if it is stored properly. You should check the “best by” date on the label, but you can also do a simple test by smelling and tasting the oil to check for rancidity. If the oil has a rancid or off smell or taste, it should be discarded.
- What is the smoke point of Olive Oil?
The smoke point of oil is around 190-216 °C (375-420 °F), which means it can be used for sautéing, baking, and roasting at lower temperatures, however it should not be used for frying at high temperatures. Using an oil with a lower smoke point than necessary can cause it to smoke, burn and create harmful substances.
- Can you cook with extra-virgin olive oil?
Yes, you can cook with extra-virgin olive oil, but it is best to use it for low to medium-heat cooking such as sautéing, baking, and roasting. Due to its delicate flavor and high cost, it is often recommended to use extra-virgin oil as a finishing oil or to dress salads, pasta or bread.
- What is the difference between cold-pressed and first-pressed?
Both “cold-pressed” and “first-pressed” refer to the method used to extract the oil from the olives. Cold-pressed olive oil is made by crushing the olives and extracting the oil without the use of heat. First-pressed olive oil is made by crushing the olives and then using a press to extract the oil, with no heat applied. Both methods are considered to be less processed, and produce a high-quality oil.
