Juice is a
liquid (drink) that is naturally contained in
fruit and
vegetables. It can also refer to liquids that are flavored with these or other biological food sources such as
meat and
seafood. It is commonly consumed as a
beverage or used as an ingredient or flavoring in foods. It is also a common practice to mix juices of different fruits/vegetables. Juice did not emerge as a popular
beverage choice until the development of
pasteurization methods allowed for the preservation of juice without fermentation. The
Food and Agriculture Organization of the United Nations (FAO) estimated the total world production of citrus fruit juices to be 12,840,318 tonnes in 2012.
