SODIUM ALGINATE
Molecular formula :C5H7O4COONa Molecular weight:216

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 tasty. It also applies to the
mixed drinks, such as ice lolly, iced fruit juice and iced
milk, etc. When adding some into dairy puoducts 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 spliting open if it is
used as a cover of mild 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
pstry)jam, tomato ketchup and the canned products.
c: Hydration
Sodium Alginate will make noodle,
vermicelli or ice powder have a strong cohesiveness, pulling
, bending and reduce breaking, special suitable in the less
gluten content of wheat flour. SODIUM Alginate also can
equal the products' 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 quiken the flavor
sending forth, raise melting point of the products.
d: Coacervation
Sodium Alginate suits to make
kinds of gel product, which can be kept the fine state,
conleakge and contraction. So it also fits iced products
and man - made produds. Using this specific propety, it
can be used as a cover for fruit, meat and seaweed produds
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 son sugar,
elastic, unsticky, transparent.
2.In medical industry
a. dental impression
material
In the past dental impression
material mainly used by the mixture of rubber and plaster.
Recently it has been replaced by Sodium Alginate material.
Theis material operates easily and the marks of printing
accurately. Sodium Alginate material and Coagulant packed
seperately. When using, mix them with water, them a few
minitutes after a coagulum will come into being.
b. Hemostatic
The solution of Sodium Alginate
will have a wadding sediment, which molecular structure
is like thread. Making use of this mechanism, Sodium Alginate
can be made into all kinds of hemostatic, such as hemostic
gauze, hemostic cotton, scald gauze, spraying hemostatic,
ect.
c. Preventing
and exclusion from radioactive harmful metals
Sodium Algiante has a pecial function
of exchanging for some elements. It not only can preventing
from absorbing strontium but also have a cenain treatment
against them. Taking some Sodium Alginate before or after
absorbing strontium, then the radioactive element will be
absorbed quickly and be drained away.
d. 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, packing and printing,
mainly in printing. It, as a reactive printing agent, has
a special propety. During the chemical reaction of fibre
and reactive dye, the dye is fixed in fibre and printing
agent do not attend this reaction. Otherwise, the agent
wili 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, felling smooth. THis
agent is also suitable for cotton, wool, silk and synthetic
fibre. the products of medium and low viscosity fit for
the printing requiements 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.
b. Synthetic fibre
Mix Sodium Alginate and asbestos
shon fibre, then mixture solidify the by a solution of Calcium
Acetate. This treatment can avoid Asbestos fibre of flying
around to harm to health.
4.In other industry
Papermaking starching: When using
the solution of Sodium Alginate replacing pan 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.
Coating of the welding electrode:
The mixture of welding - coating
powder and Sodium Alginate can stick and humify the coating
of welding and make it easy to burn into ash and lighten
flying during welding operation. In addition , Sodium Alginate
can also apply to disposing of seeds, pesticide, antitoxin
and antibitic.
