Traditional stone-milled and cold-pressed olive oil retains all its vitamins, antioxidants and aromatic properties because water is never added to the milling process. The centrifugal machinery used in industrial olive oil production requires the addition of water to extract oil from the olive paste; since the vitamins and antioxidants found in the oil are water soluble, a large percentage of them are washed out when the oil and water are separated. Biolea’s oil retains all its nutritive value. The temperature of the olive paste must be kept below 27°C during all stages of production to ensure the preservation of the olive oil’s nutritive and aromatic properties.
