Understanding the Physical and Chemical Properties of Sodium Alginate

The primary component of sodium alginate is the sodium salt of alginate, a mixture of glycanuronic acid. It is obtained through the extraction of glue from brown seaweed, particularly kelp. The resultant product is a white or light yellow powder with no discernible odor or taste.

Thermal Properties

Sodium alginate has distinct solubility characteristics. It is insoluble in ethanol, ether, or chloroform. However, it readily dissolves in both hot and cold water. A 1% aqueous solution of sodium alginate exhibits a pH value between 6 and 8. When dissolved in water, it forms a viscous colloidal solution. Moreover, sodium alginate can easily mix with various substances, including proteins, starch, pectin, acacia, carboxymethyl cellulose, sucrose, glycerol, and sorbitol.

Hydrophilic Gel with Hydration Ability

Sodium alginate finds extensive application in the food industry due to its versatile properties. When added to different types of noodles, it significantly increases their viscosity, making the products stronger, more resilient, and imparting a delicate taste with a satisfying texture. The recommended dosage of sodium alginate for this purpose ranges from 0.2% to 0.5%.

Furthermore, sodium alginate proves valuable in the production of candy, cold food, and food fillings. Its inclusion improves the taste and imparts excellent gelatinability to the final products.

Additionally, sodium alginate finds applications as a textile pulp, cosmetics thickening agent, and fruit preservative. Its versatile nature and beneficial properties make it an indispensable component in numerous industries.
