Product Description

    Sodium alginate is a by-product of iodine and mannitol extracted from kelp or sargassum of brown algae. Its molecules are connected by β-D-mannuronic acid, M and α-l-Guluronic acid, G by (1→4) bonds. Sodium alginate aqueous solution has high viscosity and has been used as thickener, stabilizer and emulsifier for food.

    Sodium alginate is a non-toxic food, as early as 1938 has been included in the United States Pharmacopoeia. Sodium alginate contains a large amount of -- COO-, which can exhibit polyanion behavior in aqueous solution and has certain adhesion, and can be used as a drug carrier to treat mucosal tissue. Under acidic conditions, -coo - transforms into -Cooh, the ionization degree decreases, the hydrophilicity of sodium alginate decreases, the molecular chain shrinks, and when pH value increases, the -Cooh group continuously dissociates, the hydrophilicity of sodium alginate increases, and the molecular chain extends.

    Therefore, sodium alginate has obvious pH sensitivity. Sodium alginate can quickly form gels under extremely mild conditions. When cations such as Ca²⁺ and Sr²⁺ exist, Na⁺ on G unit will undergo ion-exchange reaction with divalent cations, and G unit will accumulate to form cross-linked network structure, thus forming hydrogels. The conditions under which sodium alginate forms the gel are mild, which avoids the inactivation of sensitive drugs, proteins, cells and enzymes and other active substances. Because of these excellent properties, sodium alginate has been widely used in food industry and medicine.

1. Application in food

    Sodium alginate is used to replace starch and gelatin as the stabilizer of ice cream, which can control the formation of ice crystals and improve the taste of ice cream. It can also stabilize mixed drinks such as sugar sorbet, ice sherbet and frozen milk. Many dairy products, such as processed cheese, whipped cream, and dry cheese, utilize sodium alginate's stabilizing action to prevent the adhesion of foods to packaging, and serve as a coating for emulsified accessories to stabilize and prevent cracking of frosting pastry.

    Sodium alginate is used as a thickening agent in salad (a kind of salad) dressings, puddings (a kind of dessert), jams, ketchup and canned products to improve the stability of products and reduce liquid leakage.
 

    Adding sodium alginate in the production of noodles, vermicelli and rice noodles can improve the cohesiveness of the product structure, make its tensile strength, bending degree, reduce the breaking rate, especially for the flour content is low gluten, the effect is more obvious. The addition of sodium alginate in bread, pastry and other products can improve the uniformity of internal tissue and water retention, and prolong the storage time. The addition of thermal fusion protection layer to frozen sweet products can improve the performance of fragrance escape and melting point.
 

    Sodium alginate can be made into a variety of gel food, maintain good colloidal form, does not occur seepage or shrinkage, suitable for frozen food and artificial imitation food. Can also be used to cover fruit, meat, poultry and aquatic products as a protective layer, with no direct contact with the air, prolong the storage time. Can also be used as bread icing, filling filler, pastry coating layer, canned food and other self-coagulation agent. In high temperature, freezing and acid medium can still maintain the original form. It can also replace the gum made of elastic, non-stick teeth, transparent crystal gummies.

2. Application in pharmaceutical preparations
 

    Sodium alginate was included in the United States Pharmacopoeia as early as 1938. Alginate was introduced into the British Pharmacopoeia in 1963. Alginate is insoluble in water, but it expands when put in water.

    Traditionally, therefore, sodium alginate is used as a binder for tablets, while alginate is used as a disintegrator for quick-release tablets. However, the effect of sodium alginate on the properties of tablets depends on the amount put into the prescription, and in some cases, sodium alginate can promote disintegration of tablets. Sodium alginate can be added during granulation, rather than in powder form after granulation, making the process simpler. Compared with the use of starch, the mechanical strength of the prepared sheet is greater.

    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 suspension of solids.

3. Application in printing and spinning industry
 

    Sodium alginate in printing and dyeing industry used as reactive dye color paste, better than grain starch and other pulp. The printed textile pattern is bright, the line is clear, the color is high, the color is uniform, the permeability and plasticity are good. Seaweed gum is the best paste in 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 printing paste.
 

    Chinese textile department mixes or substitutes starch with seaweed gum to prepare warp sizing, which not only can save a lot of grain, but also can make the warp fiber fuffle free, friction-resistant, less breakage rate, so as to improve the weaving efficiency. Seaweed gum is effective on both cotton 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 sodium diester of alginate polysaccharide, which has the function of anticoagulation, lowering blood lipid and reducing blood viscosity.

    Using seaweed gum instead of rubber and gypsum as dental impression material is not only cheap and easy to operate, but also more accurate in tooth shape.

    Seaweed gum can also be made of various forms of hemostatic agent, including hemostatic sponge, hemostatic gauze, hemostatic film, scald gauze, spray hemostatic agent, etc.
