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 or other beverages. Juice emerged as a popular beverage choice after the development of pasteurization methods allowed for its preservation without fermentation.[1] 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.[2]
