"Sugar" (Sucrose) vs High Fructose Corn Syrup
Sucrose, or "table sugar" is a sugar disaccharide composed of equal amounts of glucose (aka dextrose or d-glucose) and fructose.
Therefore, common table "sugar" contains 50% fructose and 50% glucose. Fructose makes up 70% of the sugars in apples and is the primary or majority sugar in many fruits. (1)
High fructose corn syrup (HFCS) contains the monosaccharides glucose and fructose in varying amounts depending on the formulation.
The common formulations of HFCS contain either
____ fructose (for baking) or
____ fructose (for soft drinks) (1,2)
a) 22% ; 25% (nearly half the amount in "sugar")
b) 42% ; 55% (similar amounts to common "sugar")
c) 62% ; 75% d) 92% ; 95% (nearly twice the amount in "sugar")
