Sodium Alginate

Description

Sodium alginate, also known as sodium alginate, kelp glue, alginate, and alginate, is a natural polysaccharide carbohydrate extracted from kelp. It is a white or yellowish granule or powder that is almost odorless and tasteless. It is a high viscosity polymer compound and a typical hydrophilic sol. It is widely used in food, medicine, printing and dyeing and other industries for its stability, thickening and emulsifying properties, hydration and gelling properties. Because it is actually a natural cellulose, it can slow down the absorption of fat sugar and bile salts, and has the effect of lowering serum cholesterol, blood triglycerides and blood sugar, and can prevent modern diseases such as hypertension, diabetes, and obesity. It is a popular food additive.

Application
Food grade sodium alginate is mainly used in food, adhesive, stabilizer and molding agent. In food, it is mainly used in imitation food, pasta, beverage, meat products, stuffing, jam, pet food, etc.

Chemical Structure:
Sodium alginate (C6H7O8Na)n is mainly composed of the sodium salt of alginic acid, consisting of a-L-mannuronic acid (M unit) and b-D-guluronic acid (G unit) linked by 1,4-glycosidic bonds and composed of different Copolymers composed of proportions of GM, MM and GG fragments.
