| This image is of green, unripe drupes of Olea europea. All types of edible olives are produced from green, unripe olives. Fresh olives are very bitter and are not edible. They must first be soaked in a weak salt solution. In the case of black olives, this process lasts for several months so that a lactic fermentation occurs. Then the olives are treated with sodium hydroxide. Green olives do not undergo lactic fermentation. |
