Sodium alginate (E401) – what is it?
Sodium alginate, also known as E401, is a natural polysaccharide made from brown seaweed. This food additive is valued for its unique thickening, stabilizing and emulsifying properties. Its ability to form gels and improve the texture of food products makes it indispensable in the food industry.
Due to its natural origin and biodegradability, sodium alginate is considered a safe and environmentally friendly ingredient that is used not only in food, but also in cosmetics and medicine.
Properties of Sodium alginate
Sodium alginate is distinguished by its ability to bind water, which contributes to viscosity and the formation of gel-like textures. It is also stable over a wide range of pH and temperatures, making its use very broad. In addition, it can form complexes with metals, which is used in purification processes and as a carrier of active ingredients in various products.
Applications of Sodium alginate
Sodium alginate is used in many food industries, including beverages, ice cream, sauces, jams, as well as in baked goods as an agent to improve the texture and moistness of cakes. In the cosmetics industry, it is used as an ingredient in moisturizing and masking products. In medicine, it is used in the manufacture of wound dressings and as an ingredient in toothpaste.
Where to buy Sodium alginate?
Sodium alginate is available in health food stores, specialty stores with raw materials for the food industry, and online. It is available to both large-scale manufacturers and individual consumers who want to experiment with food textures in their home kitchen.
Sodium alginate and its functions in food
In the food industry, sodium alginate serves many functions – from thickener to stabilizer to emulsifier. It helps maintain the consistency of products, prevents ingredients from delaminating and prolongs freshness. Its use allows for the creation of innovative textures and forms, making it a key ingredient in the growing molecular gastronomy sector.
