Nourisi® Sodium Alginate, a natural polysaccharide obtained from brown seaweed. It functions as a thickener, stabilizer and gelling agent in many food and industrial applications. Because it is plant-based and environmentally friendly, it is widely used in products that require clean-label ingredients and reliable performance. Sodium alginate is valued for its ability to create smooth viscosity, form calcium-triggered gels and improve overall texture in diverse formulations.

Application In Food Products
such as ice cream, yogurt and flavored milk, it helps control viscosity, improve mouthfeel and prevent ice crystal formation during freezing.
dressings and condiments to provide uniform thickness and prevent ingredient separation during storage.
sodium alginate food grade reacts with calcium to form stable and elastic gels. This property allows producers to create molded shapes, fruit gels and structured fillings with controlled texture.
to increase cooking tolerance, improve elasticity and reduce breakage.
sodium alginate helps maintain moisture, resulting in softer texture and better shelf life.
Application In Industrial Fields
as a high-quality printing paste due to its smooth viscosity, clean wash-out behavior and excellent color absorption.
it contributes to thickening, stabilizing emulsions and forming smooth films.
sodium alginate is applied in controlled-release tablets and wound dressings because of its biocompatibility and gel-forming ability.
paper processing and other industrial operations that require stable and reliable viscosity control.
Sodium alginate provides stable viscosity over broad temperature ranges and helps prevent separation in liquid systems.
It forms flexible and controlled gels in the presence of calcium, allowing manufacturers to create defined textures and shapes.
It disperses easily in water and offers good moisture-retention performance, contributing to improved product quality and shelf life.
