High-fructose Corn Syrup (HFCS) 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 common types of high-fructose corn syrup are: HFCS 90 (mostly for making HFCS 55 ), approximately 90% fructose and 10% glucose; 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.
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.
High fructose corn syrup ( HFCS ) is a corn sweetener found in numerous foods and beverages on the grocery store shelves. HFCS is composed of either 42% or 55% fructose, with the remaining sugars being glucose and higher saccharides. As such, HFCS is extremely similar to regular table sugar (sucrose), which is a 50/50 blend of fructose and glucose. There is very little pure fructose as a single sugar in the diet. It is usually found together with glucose
