E401 Sodium Alginate Description:

Sodium Alginate is the sodium salt of a carboxymethyl ether of cellulose, which has been partially hydrolyzed by enzymatic treatment with food-grade Trichoderma reesei cellulase.

Sodium Alginate is the white crystal whose appearance and smell are similar to sugar.

Sodium Alginate Features：

In the food industry, Sodium Alginate has the functions of stabilization, hydration, thickening and emulsification.

In the pharmaceutical industry, it can be used as dental impression material, ointment, tablets and their preparation, and hemostat.Sodium Alginate also can be used in resin coating, rubber cream agent, water treatment and so on.

Sodium Alginate Description：

In Foods,Alginate has an excellent functionality as a thickening agent, gelling agent, emulsifier, stabilizer, texture-improver (for noodles), to improve the quality of food. Nowadays, based on unique and excellent properties alginate is applied to numerous kinds of food, such as ice cream, jelly, lactic drinks, dressings, instant noodle, beer, et cetera .Safety of alginate for food applications is certified by FAO/WHO, as one of the safest food additives.
