Sodium alginate
Sodium alginate is a water-insoluble, gelatinous, cream coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Adding artificial flavours and colours creates a more tasty edible slime.
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 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
