Alias：Alginic acid potassium salt; Alginic acid, potassium salt;
Molecular formula ：(C6H7O6K)n
Molecular weight ：32000～250000
C A S ： 9005-36-1
chemical property ：
1. colorless or light yellow fibrous powder, nearly odorless, tasteless.
2. soluble in aqueous viscous liquid, insoluble in ethanol, ether and chloroform.
3.1% of the aqueous solution pH value is 6 ~ 8, the aqueous solution viscosity stable at pH 6 ~ 9, when there are high ions such as Ca can form gel.
4.can and carboxymethyl cellulose, protein, sugar, starch and most of the water soluble glue phase compatibility.
Potassium alginate use:
This product as a emulsifying stabilizer and thickener, is mainly used for the mask, such as dental impression material, also used in electrode covering, used in food, cosmetics, etc., can also be used for dairy products, canned fruit, sausage casing, rules can be used in all kinds of food in our country, according to production need to moderate use.
