About the Nutrients in Olives
Green olives are olives that were picked before they are ripened. Black olives were picked ripe and dipped in an iron solution to stabilize their color. After they are picked, green lives and black olives are soaked in a milk solution of sodium hydroxide and then washed thoroughly in water to remove oleuropein, a naturally bitter carbohydrate.
Then green olives may be allowed to ferment before they are packed in a brine solution. Black olives are not allowed to ferment before packaging, which is why they taste milder than most green olives. Green olives that do not ferment before packing taste as mild as black olives.
