The acidity level in this olive oil is very low and oleic acid is not harmful for human body. Less than 0.3% oleic acid is available in this olive oil. Virgin olive oil is used to extract this olive oil. The refining method is different from all other methods of olive oil production. After refining the olive oil, all the defects are traced and removed. Olive oil produced from Mediterranean area is gathered for refining to produce high quality oil.
Refined olive oil is edible oil and no solvents are allowed to be use in the refining process. Physical filters, chemicals and charcoal are used to refine the olive oil for increasing the quality. As the oil is refined from previously extracted olive oil, the color, flavor and taste will be diminished. In some countries of the world, this olive oil is not granted for human consumption. They think low flavor and safety concern of refined olive oil will be harmful for human being. But this olive oil sis not officially rejected for human being.
