Corn Starch Sugars
Fructose syrup · F42 / F55
Fructose syrup includes F42 and F55. A commonly used concentration is 77%, mainly for beverage sweetening.
F42 / F55Typical fructose syrup concentration: 77%
Product overview
- Includes MVR evaporation, isomerization, F42 purification and F55 separation/blending.
- Widely used as a sweetener in carbonated and other beverages.
Starch sugars include glucose, maltose and fructose syrups. Glucose syrup is generally used for fermentation; maltose syrup for food browning/coloring, moisture retention and taste; fructose syrup as a beverage sweetener.
F42 and F55 product routes, including CCP1 and CCP4 control points.
Figures & advantages
Low-consumption production
Low steam, electricity, acid/alkali and water consumption per unit of product. Uses mature maltose and fructose production technology.
Typical KORN process figures and technical advantages. Final parameters are subject to project design and the technical agreement.
