Sodium Bisulfite- Industrial/Technical Grade
bisulfite is a fine crystallized sodium grain that releases sulfur gas when
dissolved in liquid. Manufacturers use sodium bisulfite in foods, cleaning
products and pharmaceutical research. Common uses for sodium bisulfite
include food preservation and cleansing to sanitize equipment and kill mold,
bacteria and germs. Additionally, metal workers use sodium bisulfite to
Sodium Bisulfite is widely used in various
Sodium bisulfite is used as leather processing
chemical to make finished leather products softer, wearable, waterproof and
Sodium Bisulfite plays an important part in the
treatment of water, wastewater and waste as a strong reducing agent.
The chemical removal of dissolved oxygen by chemically treating with sodium
bisulfite reduces the corrosion rate in steel material. Sodium bisulfite
also assists in the dechlorination of drinking water as well as in the
chlorine removal in waste waters. Another treatment method that utilizes
sodium bisulfite's effectiveness is in the reduction of chromium. All three
reactions allow for chemical removal to be controlled by the amount of
sodium bisulfite that is reacted with the solution.
The medicine industry uses Sodium Bisulfite for
manufacturing semifinished product of metamizole sodium and aminopyrine.
Sodium Bisulfite is used in Rubber Industry as
Sodium bisulfite is an important component in
the preparation of dye intermediates. There are also areas of substantial
utilization in the processing of wool as well as for the antichlor treatment
required of many textile products.
Sodium bisulfite is a common reducing
agent in the chemical industries. In biochemical engineering applications,
it is helpful to maintain anaerobic conditions within a reactor.
Sodium bisulfite serves as dual purpose in
photographic industry. It is responsible for preserving the thiosulfite in
the fixing baths and scavenging the dissolved oxygen in the developer
Sodium bisulfite is also used in the process of
purifying water, cleaning water pipes and reverse osmosis membranes in
desalinization equipment as it is an antibacterial. It is usually added to
large piping systems to prevent oxidative corrosion.
Food Grade sodium bisulfite is used to preserve and
extend the shelf life of manufactured food items. As an additive, the food
processing chemical helps to prevent the oxidation of fresh-cut produce.
- It is used to preserve color and inhibit bacterial growth on fruits,
vegetables, some seafood and wine.
- Sodium bisulfite can preserve many of the qualities of fruits and
vegetables, including the color, taste and nutritional value. It is a
common ingredient used in the canning process; the sodium bisulfite
protects the fruits and vegetables from oxidizing and changing color.
- Sodium bisulfite is used in beverages, fillings, sauces, dressings.
- Soft drink manufacturers use the pH-lowering properties of sodium
bisulfite to reduce the tartness of many beverages.
- It is also present in wines and beers, as it is used as both a
sterilizer and an antioxidant in the process of brewing beer or
- Sodium bisulfite acts as bleacher (Sweet, pastry, water-soaked bamboo
slices, etc.) loosening agent (bread, biscuit, etc.) corrosion
resistance antiseptic (fruit juice, can, brewing, grain storage, etc.);
antioxygen antistaling agent (acupuncture needle sprout, sea food,
garden stuff, etc.)
For starch industry, Sodium bisulfite is added to the
corn syrup as a preservative. It acts as a preservative agent.
