High-fructose corn syrup

High-fructose corn syrup (HFCS) – called isoglucose in Europe and glucose-fructose in Canada – comprises any of a group of corn syrups that has undergone enzymatic processing to convert its glucose into fructose and has then been mixed with pure corn syrup (100% glucose) to produce a desired sweetness. In the United States, HFCS is typically used as a sugar substitute and is ubiquitous in processed foods and beverages, including soft drinks, yogurt, cookies, salad dressing and tomato soup.

The most widely used types of high-fructose corn syrup are: HFCS 55 (mostly used in soft drinks), approximately 55% fructose and 45% glucose; and HFCS 42 (used in many foods and baked goods), approximately 42% fructose and 58% glucose. HFCS-90, approximately 90% fructose and 10% glucose, is used in small quantities for specialty applications, but primarily is used to blend with HFCS 42 to make HFCS 55.

The process by which HFCS is produced was first developed by Richard Off. Marshalle and Earl P. Kooi in 1957. The industrial production process was refined by Dr. Y. Takasaki at Agency of Industrial Science and Technology of Ministry of International Trade and Industry of Japan in 1965–1970. HFCS was rapidly introduced to many processed foods and soft drinks in the U.S. from about 1975 to 1985.

Per relative sweetness, HFCS 55 is comparable to table sugar (sucrose), a disaccharide of fructose and glucose. That makes it useful to food manufacturers as a substitute for sucrose in soft drinks and processed foods. HFCS 90 is sweeter than sucrose; HFCS 42 is less sweet than sucrose.
