Curdlan Gum is a food-grade natural, neutral, linear β-1,3-glucan polysaccharide produced by fermentation of Agrobacterium biobar 1.We supply bulk Curdlan Gum sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Curdlan Gum is widely used in ramen, seafood analogues, meat products: ham, tofu texturisation and heat-stable custards.
Curdlan Gum (E424) is manufactured by submerged fermentation, purification, and spray drying. It is a white to off-white odourless powder, insoluble in cold water but forming a suspension that gels irreversibly upon heating.
Curdlan produces two gel types: low-set (55–80 °C, reversible) and high-set (≥80 °C, thermo-irreversible). This enables unique texture modification in Asian noodles, fishballs, sausages, and plant-based meats.
