Uses and synthesis of Curdlan powder

Curdlan powder, a water-insoluble glucan produced by microorganisms and composed of β-1 (1→3) monoglucoside bonds, is a general term for a class of polysaccharides whose suspension can be heated to form both hard and elastic thermally irreversible gel and thermally reversible gel. Curdlan is widely used in various fields of the food industry due to its good processing adaptability such as water retention, freezing resistance, heat resistance, adhesion and film forming properties. Various special preparations for different foods have been developed and applied. Curdlan powder can be used both as food additive and as the main ingredient in food.

Applications/Functions of Curdlan powder

1. Curdlan powder is widely used in various fields of food industry due to its good processing adaptability such as water retention, freezing resistance, heat resistance, adhesion and film forming properties. Various special preparations for different foods have been developed and applied.
2. Curdlan can be used both as a food additive and as the main ingredient in food.

Physicochemical Property of Curdlan powder

Curdlan white to nearly white powder, almost odorless. l% water suspension heated to 54 ~ 78℃, and then cooled to below 40℃, can form a gel, the gel reheated to 54 ~ 78℃, still soluble, this is a heat reversible gel.

Production methodprocess of Curdlan powder

Curdlan powder is produced by the non-pathogenic and non-toxic strain alcaligenes or actinomycete of Gram-negative Agrobacterium by pure culture and fermentation. The condensed polysaccharide accumulated in the medium is dissolved with alkali, the bacteria are separated, and then neutralized, concentrated, precipitated, washed, dried and crushed with acid.
