Products main application 

1. In food industry 

A: Stabilizer 
As a stabilizer of ice cream replacing starch and carrageenan, Sodium Alginate can avoid of ice crystal and make the product tas ty. It also applies to the mixed drinks, such as ice looly, iced fruit juice and iced milk, etc. When adding some into dairy products like refined cheese, canned cream and dry cheese, the final product will not stick to the package. Moreover, Sodium Alginate can keep the product fine and avoid of splitting open if it is used as a cover of milky food. 

B: Thickener and emulsion 
Sodium Alginate can raise the product＇s stabilization and decrease the liquid out when it is used in sala (a cold dish)flavoring, pudding (a sweet pastry) jam, tomato ketchup and the canned products. 

C: Hydration 
Sodium Alginate will make noodle, vermicelli or rice noodle have a strong cohesiveness, pulling, bending and reduce breaking, stabilization and decrease the liquid out when it is used in sala (a cold dish)flavoring, puddingspecial suitable in the less gluten stabilization and decrease the liquid out when it is used in sala (a colddish)flavoring, puddingcontent of wheat flour, SODIUM Alginate also can equal the product＇s internal form and hold water so that it can be kept for a long time. Adding some into iced sweet products, Sodium Alginate will come into being a protecting cover against heated quickly, and it can quicken the flavor sending forth, raise melting point of the 
products. 
D: Gelling property 
Sodium Alginate suits to make kinds of gel product, which can be kept the fine state, nonleakage and contraction. So it also fits iced products and man-made products. Using this specific property, it can be used as a cover for fruit, meat and seaweed products away from air and keep it stored longer. In addition, it also can be used as the sugar coating of bread, the cover of filling and cake and the auto-coagulant of canned food, which will not change in high/low temperature and acid conditions. It also can replace carrageenan to make a crystal soft sugar, elastic, unsticky, transparent. 

2. In medical industry 

A: dental impression material 
In the past, dental impression materials are mainly used by the mixture of rubber and plaster. Recently it has been replaced by Sodium Alginate material. This material operates easily and the marks of printing accurately. Sodium Alginate material and Coagulant packed seperately. When using, mix them with water, then a few minitutes coagulum will come into being. 

B: Mostatic 
The solution of Sodium Alginate will have a wadding sediment, which molecular structure islike thread. Making use of this mechanism, Sodium Alginate can be made into all kinds of hemostatic, such as hemostatic gauze, hemostatic cotton, scald gauze, spraying hemostaitc, etc. 

C: Preventing and exclusion from radioactive harmful metalsSodium alginate has a special function of exchanging for som eleme nts. It not only can preventing from absorbing strontium but also have a certain treatment against them. Taking some Sodium Alginate before of after absorbing strontium, then the radioactive element will be absorbed quickly and be drained away. 

D. salve, tablet and their agent 
Salve, tablet and drugs Using of the thickener and coacervation, Sodium Alginate can be made into all kinds of additive of medicines, such as Sulphur Paste mixed by Sodium Alginate and wool oil which can treat skin disease. Sodium Alginate can be mixed with sulphanilamide into eye ointment or with benzene mercury acetate into contraceptive jelly. If Sodium Alginate used as capsule for intestines, it can cause the medicine staying and absorbing longer in the intestines then have a good curative effect. 

3. in printing and textile industry 

A: printing agent 
It has been a long history that sodium alginate is used in starching, finishing and printing, mainly in printing. It, as a reactive dye printing agent, has a special property. During reaction of fibre and reactive dye, the dye is fixed in fibre and printing agent do not attend this reaction, Otherwise,the agent will be fixed in the fibre and make it hard, fragile and bad color, if you use Sodium Alginate as a printing agent, it not only affects the dyeing reaction but also makes

the product outline clear, color bright, feeling smooth. This agent is also suitable for cotton, wool, silk and synthetic fibre. The products of medium and low viscosity fit for the printing requirements by net or roll style. Actually the printing agent mixed with low-viscosity Sodium Alginate is stabler than with the other viscosity, which is the results to produce a high content of printing agent. This agent will make a dense cover during drying and raise dyeing. High quality sodium alginate sizing can meet special, requirement of spray-printing. 

B: Synthetic fibre 
Mix Sodium Alginate and asbestos short fibre, then mixture solidify by the solution of Calcium Acetate. 

4. In other industry 

A. Papermaking starching 
When using the solution of Sodium Alginate replacing part of Rosin as dispering agent of paper pulp of paper surface starching, it can make paper glooss and smooth, raise the absorption of printing ink, wax, soil and paper＇s pliability and tough.B. Coating of the welding electrodeThe mixture of welding-coating powder Sodium Alginate can stick and humify the coating of welding and make it easy to burn into ash lighten flying during welding operation.In addition, Sodium Alginate can also apply to treatment of seeds, pesticide, antitoxin and antibiotic.
