Sodium alginate is a by-product of extracting iodine and mannitol from brown algae kelp or Sargassum. Its molecule consists of β-D-mannuronic acid (β-D-mannuronic, M) and α-L-guluo Uronic acid (α-L-guluronic, G) is connected by (1→4) key. It is a natural polysaccharide with the stability, solubility, viscosity and safety required for pharmaceutical excipients. Sodium alginate has been widely used in the food industry and medicine.

1. Application in food
Sodium alginate is used as a stabilizer for ice cream instead of starch and gelatin. It can control the formation of ice crystals and improve the taste of ice cream. It can also stabilize mixed beverages such as sorbet, sherbet, and frozen milk. Many dairy products, such as refined cheese, whipped cream, dry cheese, etc., use the stabilizing effect of sodium alginate to prevent the stickiness of food and packaging. It can be used as a cover for dairy accessories to stabilize it and prevent frosting The skin is cracked.
Sodium alginate is used as a thickener for salad (a cold dish) sauce, pudding (a dessert), jam, tomato sauce and canned products to improve the stability of the product and reduce liquid leakage.
Adding sodium alginate in the production of dried noodles, vermicelli, and rice noodles can improve the adhesion of the product structure, make it strong in tension, large in bending, and reduce the rate of broken ends, especially for low gluten in flour, and the effect is more obvious. Adding sodium alginate to bread, cakes and other products can improve the uniformity and water retention of the internal tissue of the product, and extend the storage time. Adding to frozen dessert products can provide a thermal fusion protective layer, improve fragrance escape, and improve the performance of melting point.
Sodium alginate can be made into various gel foods, maintains a good colloidal form, does not leak or shrink, and is suitable for frozen foods and artificial imitation foods. It can also be used to cover fruits, meat, poultry and aquatic products as a protective layer, without direct contact with the air, and prolong the storage time. It can also be used as a self-aggregating agent for bread icing, fillings, dessert coatings, and canned foods. It can maintain its original shape in high temperature, freezing and acidic media. It can also replace agar to make elastic, non-sticky, transparent crystal jelly.
2. Application in pharmaceutical preparations
Sodium alginate has been included in the United States Pharmacopoeia as early as 1938. Alginic acid was included in the British Pharmacopoeia in 1963. Alginic acid is insoluble in water, but will swell when placed in water. Therefore, traditionally, sodium alginate is used as a binder for tablets, and alginic acid is used as a disintegrant for immediate-release tablets. However, the effect of sodium alginate on tablet properties depends on the amount put in the prescription, and in some cases, sodium alginate can promote the disintegration of the tablet. Sodium alginate can be added during the granulation process, rather than in the form of powder after granulation, so that the production process is simpler. Compared with the use of starch, the resulting tablets have greater mechanical strength.
Sodium alginate is also used in the production of suspensions, gels and concentrated emulsions based on fats and oils. Sodium alginate is used in some liquid medicines to enhance viscosity and improve the suspension of solids. Propylene glycol alginate can improve the stability of emulsions.
3. Application in printing and textile industry
Sodium alginate is used as a reactive dye paste in the printing and dyeing industry, which is superior to grain starch and other pastes. The printed textile has bright patterns, clear lines, high color yield, uniform color, and good permeability and plasticity. Seaweed gum is the best slurry for modern printing and dyeing industry. It has been widely used in the printing of cotton, wool, silk, nylon and other fabrics. It is especially suitable for the preparation of dyeing printing slurry.
China's textile sector uses alginate and starch to mix or replace starch to prepare warp sizing, which not only saves a lot of food, but also makes the warp fibers lint-free, friction-resistant, and less end-breaking, thereby improving the efficiency of weaving. Seaweed gum is effective on cotton fibers and synthetic fibers.
4. Application in the pharmaceutical industry
The PS type gastrointestinal double contrast barium sulfate preparation made of alginate sulfate dispersant has the characteristics of low viscosity, fine particle size, good wall adhesion and stable performance.
PSS is a kind of fucoidan diester sodium developed with alginic acid as raw material. It has the functions of anticoagulant, lowering blood lipid and lowering blood viscosity.
Using seaweed glue instead of rubber and gypsum as dental impression materials is not only cheap, easy to operate, and the printed tooth profile is more accurate.
Seaweed gum can also be used to produce various dosage forms of hemostatic agents, including hemostatic sponge, hemostatic gauze, hemostatic film, scald gauze, spray hemostatic agent, etc.
