Corn Syrup High Maltose
High fructose sweeteners begin with enzymes which isomerize dextrose to produce a 42% fructose syrup. By passing 42-HFCS through a column which retains fructose, refiners draw off 90% HFCS and blend it with 42-HFCS to make a third syrup, 55-HFCS. All the syrups share advantages - stability, high osmotic pressure, or crystallization control, for example - but each offers special qualities to food manufacturers and consumers. 42-HFCS is popular in canned fruits, condiments, and other processed foods which need mild sweetness that won't mask natural flavors. Sweeter 55-HFCS has earned a commanding role in soft drinks, ice cream, and frozen desserts. Supersweet 90-HFCS is valued in natural and "light" foods, where very little is needed to provide sweetness. Crystalline fructose's capacity to produce greater sweetness in combination with sugar makes it useful in presweetened cereals, instant beverages, and other dry mix products.
