What is the difference between glucose-fructose syrup and High fructose corn syrup?
When I saw your question, I wondered myself what the difference might be, since they are both a mixture of two monosaccharides (glucose and fructose). As an aside, sucrose (table sugar) is also composed of glucose and fructose but they are bound by a glycosidic bond into disaccharides. First, there are many types of HFCS (high fructose corn syrup) – sometimes they are labeled – like, HFCS-90 which means 90% F and 10% G. Most of the HFCS used in food products in this country are about 55% F and 45% G (so, not a lot different than table sugar which is converted into G and F by the time it hits the stomach due to high acid gastric juices). By law, G-F syrup is any combo of G and F that contains more than 5% F…so, I guess that means that HFCS is a type of G-F syrup. Sports drinks many times contain G-F syrup. If you Google F-G syrup, you can see the different companies that make it with varying levels of F. The idea is that F , which is lower in the glycolytic pathway (turning sugar into
