Product description
Sodium alginate, also called as Algin, is a kind of white or light yellow granular or powder, almost odorless and tasteless.It is a macromolecular compound with high viscosity, and a typical hydrophilic colloids. Because of its properties of stability, thickening and emulsifying, hydratability and gelling property, it is widely used in food, pharmaceutical, printing and dyeing, etc.
Function of Sodium alginate:
Its functional properties are as follows:
(1) strong hydrophilic, can be dissolved in cold and warm water, forming a very viscous homogeneous solution.
(2) The real solution formed has softness, uniformity and other excellent properties that are difficult to obtain by other analogs.
(3) It has a strong protective effect on colloid and strong emulsifying ability on oil.
(4) Adding aluminum, barium, calcium, copper, iron, lead, zinc, nickel and other metal salts to the solution will generate insoluble alginate. These metal salts are buffers of phosphates and acetate of sodium and potassium, which can inhibit and delay solidification.
Application of Sodium alginate
Sodium Alginate is a gum obtained as a sodium salt of alginic acid, which is obtained from seaweed. It is coldand hot-water soluble, producing a range of viscosities. It forms irreversible gels with cal- cium salts or acids. It functions as a thickener, binder, and gelling agent in dessert gels, puddings, sauces, toppings, and edible films. In the manufacture of ice cream where it serves as a stabilizing colloid, insuring creamy texture and preventing the growth of ice crystals. In drilling muds; in coatings; in the flocculation of solids in water treatment; as sizing agent; thickener; emulsion stabilizer; suspending agent in soft drinks; in dental impression preparations. Pharmaceutic aid (suspending agent).
