Sodium alginate Molecular formula: C5H7O4COONa
Main use:
The algin is used as binder, plasticizer , emulsifier, stabilizer
and dyeing auxiliaries and so on in many aspects like food, frozen
food, bionic food, curative effect food, feedstuff, beverage,
printing and dyeing, medicament and daily chemical products etc in
our country.
() Printing and dyeing industry
1. Dyeing auxiliaries of active dyestuff
Sodium alginate is used as active dyestuff in printing and dyeing
industry that is better than foodstuff amylum and other plasm. The
textile that is printed by it has fresh grains, clear line, high
coloring capacity, even painting, good penetrability and
plasticity. Sodium alginate is the best plasm for modern printing
and dyeing, which is wide used for cotton, feather, silk and nylon
and other textile; furthermore, it is applicable for discharge
printing paste.
2.warp yarn stiffening material
Textile department of our country makes sodium alginate and amylum
combine or |
| |
replace amylum to confect warp, which not only can save lots of
food, but also can make fiber of warp have lots of good
characteristics such as no fuzz, bearable and little decollation;
therefore, it enhances the efficiency of weaving. Sodium alginate
is good for cotton fiber and compound fiber.
() Food industry
1. Food
It can increase effect of gluten in flour taking sodium alginate as
additive of fine dried noodles. It can eliminate adhesion stress of
noodle organization, reduce rate of broken and wetted flour,
enhance rate of quality goods; furthermore, it can restrain the
acid of noodle. It doesn't stick and muddy soup with pliability and
tasty. The specific volumetric dilatation of bread taking sodium
alginate as additive is very high; the organization of this bread
is fine with light, good flexibility, good capacity of anti-dryness
and long period of storage.
Sodium alginate can also be used as emulsifier of cake; sodium
alginate can replace pectin and agar to manufacture snack;
furthermore, it can be used to manufacture superior curative effect
food like sodium alginate panocha etc.
The flexile vermicelli often takes sodium alginate as additive.
2. Frozen food
It has special capacity and high benefit with sodium alginate
replacing traditional agar, glutin and amylum as stabilizer of
water ice and ice-cream; furthermore, this kind of water ice,
ice-cream has many good characteristics such as little ice dregs,
fine cream body and good taste; it increases two times of
anti-thaw.
3. Beverage
It has been lots of years that sodium alginate and algin propylene
diester is used as stabilizer of beer.
4. Simulated food
The jelly fish that takes sodium alginate as main raw material not
only has the natural crisp and taste, but also is very convenient
to eat with many good characteristics such as reasonable price. It
can be cold and dressed with sause and also can be boiled, which is
better for cold and dressed with sause. The man-made grape, fruit
and man-made cherry also takes sodium alginate as raw material;
meanwhile, the form, color and taste of bionic food is same with
natural fruits.
5. Curative effect and health care food
It can produce other superior curative effect food except algin
panocha by taking s odium alginate as raw material.
() Medicament industry
PS type stomach intestine double contrast barium sulfate
preparation that is made by dispersant of sodium alginate sulfate
has many good characteristics such as low viscidity, thin
granularity, good adhesive capacity and stable capacity etc.
PSS is one kind of sodium amylase diester sodium that takes sodium
alginate as raw material, which has the characteristic of
anti-cruor, reducing the viscidity of blood fat and blood. It not
only has reasonable price and convenient operation, but also can
print exact teeth form with sodium alginate replacing the dentistry
moulage material of rubber and gesso. Algin can also be used as
haemostatic including hemostasia sponge, hemostasia gauze,
hemostasia film, scald pledget and spray haemostatic etc. | Physics and chemistry index |
