How is olive oil refined? Refining olive oil process

Understanding the Refining Olive Oil Process

If you're curious about the refining olive oil process, you're in the right place! This page unlocks the mysteries behind how low-quality, non-edible olive oils are transformed into marketable products.

Many factors contribute to the quality of olive oil, including acidity levels, aroma, and flavor. A poor-quality olive oil has high acidity, large amount of insoluble matter, bad aroma and flavor, and bad color.

The refining process addresses these challenges, making oils more palatable and appealing for consumers. Here's a closer look at the key steps involved:

Degumming:

This process removes insoluble impurities, such as gums (phospholipids), in the oil. Usually, phosphoric acid or citric acid water is used.

Neutralization with Alkali:

This step removes free fatty acids by the use of an alkali, such as caustic soda (sodium hydroxide).

Decolorizing:

This step is used to decolorize the oil by filtration or treatment with absorbent clay.

Soft Deodorization:

This process eliminates undesirable odors by purging nitrogen gas into the oil at a temperature as high as 250 °C.

Enrichment with VOO:

This enhances the flavor and quality of the oil. Usually, 5–15% by volume of the virgin olive oil is added.

Understanding these steps not only helps you appreciate the quality of olive oil but also empowers you to make informed choices for your kitchen.

Don't settle for mediocre oils when you can enhance your dishes with the best. Discover the difference today!
