High fructose corn syrup: A sweetener produced by enzymatic processing of corn syrup to isomerize some of the glucose (an aldohexose carbohydrate) into fructose (a ketohexose carbohydrate). As a sweetener, high fructose corn syrup is more economical than sucrose and therefore has been widely used in processed foods and beverages.

High fructose corn syrup is an aqueous solution of glucose and fructose.
