GENERAL DESCRIPTION AND APPLICATIONS |
||
| Sodium Alginate, completely soluble in water, is the sodium salt of Alginic acid derived from selected varieties of brown seaweed. Sodium Alginate's unique property is to form gels when combined with calcium ions without heating. This reaction is widely used throughout the industry to texturize and stabilize many food products. In the food industry, sodium alginate is used for gelling, thickening, stabilizing and film forming properties. It is also widely used in textile industry to improve brigheness and strength yarns, in the printing and dyeing industry as a thickening agent, in paper industry, in dental Industry, in cosmetic Industry, in water Treatment and in medical industry. | ||
