# Fructose-Glucose Syrup Blends for Beverages: Brix, Viscosity and Mouthfeel

Fructose is sweeter than glucose and is perceived earlier, while glucose brings body and a cleaner finish. Blending the two lets formulators tune sweetness, mouthfeel and cost without changing the total solids.

Sweetness profile
-----------------

Fructose delivers a rapid sweetness peak, which reads as fresh in fruit drinks. Glucose and maltose contribute a rounder, slower sweetness and more body. A blend often tastes more balanced than either syrup alone at the same Brix.

Viscosity and handling
----------------------

At equal solids, higher-fructose syrups are slightly less viscous, which can help with pumping and filling. Viscosity still depends strongly on temperature, so dose by weight and verify at line temperature.

Stability considerations
------------------------

- Fructose is hygroscopic and can pick up moisture in humid filling rooms
- Acid plus heat increases colour formation, so pasteurisation time matters
- Blends should be stored below the temperature that promotes Maillard browning
- Keep tanks sealed to limit condensation on the surface

Formulation tips
----------------

Match the sweetness of the target profile first, then adjust total solids for body. Test at the finished Brix, not in a diluted bench sample, because sweetness perception changes with concentration and acidity.

Specifications to agree
-----------------------

Define fructose and glucose content, dry solids, pH, colour and sulphite content in the purchase specification. Ask for a certificate of analysis per lot and keep a retained sample for sensory comparison.
