Fruit juice is a kind of beverage extracted or pressed from the natural liquid contained in fruits and vegetables. It can also refer to liquids flavored with these or other sources of biological food, such as meat and seafood, such as clam juice. Fruit juice is usually consumed as a beverage, or as an ingredient or flavoring for food or other beverages such as smoothies. With the development of pasteurization, juice has become a popular beverage choice, which can be preserved without fermentation. The food and Agriculture Organization of the United Nations (FAO) estimates that the total output of orange juice in the world in 2012 is 12840318 tons. The biggest juice consumers are New Zealand (nearly one or eight ounces a day) and Colombia (more than three-quarters of the cups a day). Fruit juice consumption increases with the national income level on average.
