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.

E401 Sodium Alginate Function
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.
E401 Sodium Alginate Application
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.
In texile,Alginate is used for substrate of color paste when applying
patterns to print fabrics, scarf, towel, etc. Use of alginate for
printing of cotton, jute, rayon is mandatory. Alginate, a seaweed
extract, is safer and easier to be decomposed compared with other
substrate for textile printing, and gives easier waste water disposal.
