What is Curdlan ?

Curdlan is fermented polysaccharides made from glucose. It has a property of solidifying when heated, excellent stability, and unchangeable by freezing and thawing in structure.

Function of Curdlan

Gel function

Gel strength of curdlan increases with heating temperature, time and concentration. Gels with different properties are made depending on the way of heating.

▶heat irreversible gel (high set gel) Gel is dispersed in water and heated to 80 ℃or higher, and it becomes an irreversible gel (high set gel) and insoluble even after reheating.

▶thermoreversible gel (low set gel) Gel is dispersed in water and heated to 60℃, and it becomes a thermoreversible gel (low set gel).

Gel

The curdlan gel has high freezing tolerance, and even if it is repeatedly frozen and thawed, the physical properties hardly change.

Acid and alkali resistance

Gels are formed in a wide pH range of pH 2 to
10, and even when the pH changes,
there is almost no change in gel strength.

Heat resistance (retort tolerance)

Curdlan gel has high heat resistance and it will not break even if it is retorted.

Viscosity

By crushing curdlan gel into a paste, fat-like viscous substances with less spinnability is made.

Oil soluble substance inclusion
(emulsion gel formation)

Emulsions of fats and oils are gelated and incorporated into the gel.
