Food
Alginate is widely used in the Food Industry as a gelling, thickening, stabilizing, emulsifying and texture improving agent. Alginate forms stable gels at high and low temperatures, making it ideal for stability applications. The hydrophilic nature of alginate aids moisture retention and improves food texture. Alginate also helps prolong the shelf life of food products.
Common Applications of Alginates in Food

Ketchups / Sauces / Beverages

Alginate Properties
As a natural water soluble polymer, alginate forms viscous solution when dissolved in water. It is used as a stabilizer to prevent separation, sedimentation or settling down of any ingredients.

Dressings / Mayonnaise

Alginate Properties
It has an oil/water emulsifying capacity and is used as a stabilizer to prevent separation, sedimentation or settling down of any particles/ingredients in salad dressings, mayonnaise etc.

Jams / Marmalades

Alginate Properties
Alginate improves the texture and consistency of Jams. Alginate retains moisture which improves spreadability of Jams.

Ice cream

Alginate Properties
In Ice cream, Alginate controls the product’s viscosity, increases heat-shock resistance and reduces shrinkage and ice crystal formation. It endows the ice cream with the desired melting characteristics and provides creamy mouthfeel.

Bakery

Alginate Properties
Adding Alginate to bakery products can improve their quality. When used in the production of bread and cakes, it can make them swell further, increase the volume, loosen the texture, reduce crumbs falling down when slicing, and also prolongs the shelf life.
