Knowra High-fructose corn syrup High-fructose corn syrup High-fructose corn syrup is a liquid sweetener made by enzymatically converting some glucose in corn syrup into fructose. Its common formulations contain roughly 42% or 55% fructose among their sugars.
Corn syrup : Corn syrup is a glucose-rich sweetener produced by breaking down starch from corn. It is the glucose-rich starting material from which high-fructose corn syrup is made.
Richard O. Marshall : Richard O. Marshall was an American biochemist who helped develop enzymatic glucose-to-fructose conversion. His research helped establish the technology underlying commercial HFCS.
Soft drink : A soft drink is a nonalcoholic beverage, often carbonated and sweetened. HFCS-55 is a common sweetener in many United States soft drinks.
Added sugar : Added sugar is sugar introduced during food processing or preparation rather than naturally present in intact foods. HFCS is one source of added sugar in diets.
Starch hydrolysis : Starch hydrolysis breaks starch molecules into smaller carbohydrates using water, often with enzymes or acids. It releases the glucose-rich sugars that are processed into corn syrup.
Earl R. Kooi : Earl R. Kooi was an American chemist who developed methods for producing fructose from glucose. His work with Marshall advanced practical production of the sweetener.
Processed food : Processed food is food altered from its original state through preparation, preservation, or manufacturing. HFCS is used across packaged foods for sweetness, texture, and handling properties.
Fructose : Fructose is a monosaccharide found in fruit, honey, and many sweeteners. Its proportion in HFCS motivates questions about metabolism and health effects.
Glucose isomerase : Glucose isomerase is an enzyme that reversibly converts glucose into fructose. It performs the defining glucose-to-fructose conversion in production.
Corn wet milling : Corn wet milling separates corn into starch, oil, protein, and fiber through soaking and mechanical processing. It supplies the starch used to manufacture corn syrup and HFCS.
