Sodium alginate, also known as sodium alginate, kelp gum, alginate, and alginate, is a natural polysaccharide carbohydrate extracted from kelp. It is a white or light yellow granule or powder, 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 due to its stability, thickening and emulsifying properties, hydration and gelling properties. Because it is actually a kind of natural cellulose, it can slow down the absorption of fat sugar and bile salt, has the effect of lowering serum cholesterol, blood triglyceride and blood sugar, and can prevent modern diseases such as hypertension, diabetes and obesity. It is a popular food additive.
Food grade sodium alginate is mainly used in food, adhesives, stabilizers and molding agents. In food, it is mainly used for 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, which is composed of a-L-mannuronic acid (M unit) and b-D-guluronic acid (G unit) connected by 1,4-glycosidic bonds and composed of different A copolymer composed of GM, MM and GG fragments in proportion.
