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).  There is very little pure fructose as a single sugar in the diet. It is usually found together with glucose

How Is HFCS Used?

 HFCS is a preferred sweetener by many food and beverage manufacturers because of its high quality characteristics, including stability, high osmotic pressure, or crystallization control. For example, 42-HFCS is popular in canned fruits,  condiments and other processed foods which need mild sweetness that won't mask natural flavors.
