Sodium alginate Introduction:
H&Z® Sodium alginate is used to replace starch, gelatin as the stabilizer of ice cream, controlling the formation of ice crystals and improving the flavor of ice cream. It can also stabilize mixed beverages like sugar ice cream, sherbet, frozen milk etc. Many dairy products such as refined cheese, whipped cream, cream cheese, rely on the stabilization of sodium alginate to prevent the attachment of food and packaging materials .If it is used as the covering of milk on ornaments, the H&Z® sodium alginate can make it stable and prevent icing sugar pastry cracki
Pharmaceutical grade sodium alginate
In medicine field, sodium alginate has been widely used as pharmaceutical preparation, tissue engineering, clinical treatment, cell culture, food processing and other fields.
It can also be used as microencapsulated material and the cold resistant agents of cells.In addition, it has the functions of reducing blood sugar, antioxidant, enhancing immune activity effect etc.
With polyelectrolyte properties, sodium alginate is used to make preparation of sustained release microcapsules or pellets.
With the gel properties ,it is used to make preparation of gel matrix tablets, With its pH sensitivity ,it is used as a targeted intestinal absorption tablet disintegrate. In addition, the sodium alginate can also be used as a topical ointment thicken
Industrial grade sodium alginate
In printing and dyeing industry, sodium alginate is used as active dyestuff. It can also be used in papermaking, chemical, casting, welding electrode sheath material, fish and shrimp bait, fruit tree pest control agent, release agent for concrete, water treatment with high agglutination settlement agent etc

Sodium alginate Function:
1.Sodium Alginate is a kind of macromolecule amylose that edible but unable digestant for human body,which has functions of hygroscopicity,adsorption,cation exchane,gelling and filtration in stomach and tharm
[1]Reduce blood pressure,blood fat,cholesterin,and defend fatty liver
[2]Prevent and remove radioactive elemeent and poisonous metals
[3]Increase the paunch saturation to lose weight healthily
[4]Increase the peristalsis of the intestines and stomach to prevent
2.The low molecularized alginate has much stronger biological activity with obvious health care functions.
[1]The low molecularized potassium alginate can adjust and dufend hypertension,postpone cardiovascular caducity,improve microcirculation
[2]The low molecularized sodium alginate can reduce the blood fat
[3]The low moleclarized calcium alginate is a new source to supplement calcium,and be easy to absorb
[4]The low molecularized zinc alginate is good for brain and to defend agedness dementia
[5]The low molecularized iron alginate can supplement iron and blood
[6]The low molecularized magnesium alginate can preven and cure coronary heart disease.Also,alginate can be used for healthy function food and Pharmaceutical ,aterials.
Sodium Alginate Applications:
1.Textile grade sodium alginate is mainly applied in reactive dyes and disperses dyes printing process. It is used in roller printing,flat and rotary screen printing for cotton, flannel and canvas.
2.Food grade sodium alginate is used as food thickeners and stabilizers,emulsion .
3.Special grade sodium alginate is also widely applied in paints,water treatment,dental film, mask,welding manufacturing, pharmaceutical,cosmetics and so on.
