It has a role as a sweetening agent. It is a fructopyranose, a D-fructose and a cyclic hemiketal. A monosaccharide in sweet fruits and honey that is soluble in water, alcohol, or ether. It is used as a preservative and an intravenous infusion in parenteral feeding.

Fructose is also 1.2 times sweeter than sucrose, allowing for a reduction in the amount of sugar needed to sweeten a food during the manufacturing process. 

fructose syrups are used in many different food and beverages, mainly for their sweetening power (like sucrose), but also for additional useful properties such as taste, glossiness, improved stability and a longer shelf-life for the food products to which they are added.

There's also a flavor enhancement benefit, as the perception of sweetness from fructose actually peaks and falls earlier than glucose and sucrose.
