General description
The aqueous solutions of sodium bisulfite are acidic in nature. Degradation of sodium bisulfite with acid forms sulfur dioxide gas.
Application:
Sodium bisulfite (NaHSO3) has been used as a reagent to compose the immunoprecipitation (IP) buffer to chemically modify DNA and to synthesize arsenolipids (AsL).
Sodium bisulfite can also be used as a reagent during the synthesis of 5,6-dihydrouracil-6-sulfonate.
What is Sodium Bisulfite?
Sodium bisulfite is a food additive, antioxidant, antibrowning and preservant.
Upon heating in aqueous acidic media, it releases SO2.
In dried fruits and jams, it acts as anti-browning agent by preventing enzymatic browning caused by polyphenol oxidase.
In baking, sodium bisulfite is used as an economical alternative to common reducing agents, mainly in cookies and crackers formulations.
Origin
Sodium bisulfite is commonly obtained by treating an alkali such as sodium carbonate or sodium hydroxide with sulfur dioxide.3
Function
Sodium bisulfite has several functions in bakery systems:
Antibacterial: inhibits the growth of bacteria in high pH and high water activity conditions.
Antioxidant: reatards oxidation and rancidity, due to its oxygen scavenging properties.
Retards enzymatic browning reactions: especially in fruit products.
Reducing agent: improves flour properties by inhibiting the restoration of disulfide bonds, providing a pliable dough.
Improves dough machinability: by reducing the amount of shrinkage or set back, thus producing uniform crackers.
Nutrition and Health
In sensitive individuals, sulfites may pose potential respiratory risk. Acceptable daily intake of sulfites should not exceed 0.7 mg/Kg body weight..3
Sodium bisulfite can reduce vitamin B1 (thiamine) content in meat and fruits.
Commercial production
Sodium bisulfite can be commercially produced through the following process:4
First reaction: sodium hydroxide and sulfur dioxide are mixed in an aqueous stream to produce sodium sulfite.
Crystallization: sodium sulfite liquor is introduced into a crystallizer and a purge stream is redirected to be used in the second reaction.
Second reaction: sulfur dioxide is added to the purge stream to produce sodium bisulfite.
Second crystallization: sodium bisulfite is crystallized to obtain the solid product.
Particle reduction and packaging.
Application:
Sodium bisulfite can be used in making cookies and biscuits due to its dough conditioning and antibrowning properties.
In jams and jellies, it can be used as an antioxidant to prevent color deterioration and as an antimicrobial agent.1,2
When used in baked goods, sodium bisulfite produces the following effects:1,2
Improves sheeting by reducing shrinkage.
Improves uniformity of crackers and cookies by reducing set back and inhibiting excessive browning.
Improves dough texture by inhibiting the restoration of disulfide bonds.

Benefits of Sodium Bisulfite
As a cleaner, sodium bisulfite can help purify toxic wastewater.
For example, the authors of a paper in the February 2017 issue of Estuarine, Coastal and Shelf Science used chlorine to kill harmful bacteria in wastewater.
They then neutralized this addition with sodium bisulfite to prevent the chlorine from contaminating the water supply.
As a preservative, manufacturers add sulfites like sodium bisulfite to decrease the growth of bacteria and fungi.
This addition prevents browning and limits spoilage, according to an article featured in the October 2017 issue of PLOS One.
Aquaculture workers also use sodium bisulfite.
For example, the authors of a review published in the Journal of Food Science in October 2013 showed how sodium bisulfite greatly improved seafood's appearance.
The chemical made catfish fillets less yellow and more bright.
Manufacturers often process shrimp in a similar way, according to a paper in the January 2018 issue of the Annual Research and Review in Biology.
First, workers catch and kill the shrimp.
They then coat the them with sodium bisulfite as a bleaching agent.
Finally, they freeze the shrimp to prevent blackening.
Sodium bisulfite has been used externally for parasitic skin diseases and as a gastrointestinal antiseptic.
Sodium bisulfite is an ingredient in parenteral nutrition products for patients with severe liver disorders
Sodium bisulfite (SBS), also known as sodium bisulphite or sodium hydrogen sulfite, one of the sulfites that can be used as a preservative, antioxidant and anti-browning agent in food with the European food additive number E222.
How is Sodium Bisulfite made?
Sodium bisulfite can be commercially produced from the chemical reaction between sulfur dioxide gas with aqueous sodium hydroxide.
The following is the reaction equation:
SO2 + Na2CO3 (aqueous) –> 2 NaHSO3 + 2 CO2 (in water)
NaHSO3 is not a pure ingredient, and in fact a mixture of NaHSO3 and Na2S2O5 (sodium metabisulfite). Na2S2O5 is produced during the crystallization process of NaHSO3.
The main impurity in the product is SO42 -, as the bisulfite ion is unstable and easily oxidized to sulfate ion, so its solution cannot be stored for a long time.

Solubility
Freely soluble in water, slightly soluble in ethanol.
NaHSO3 is the main form of SO2 that dissolves in water.
The equilibrium of its different inorganic forms (sulfur dioxide, bisulfite and sulfite ions) forms should be considered.
Sodium bisulfite is a weak acid that releases sulfur dioxide gas on heating or in the presence of acids.
Sodium bisulfite dissociates bisulfite (HSO3−) when dissolved in water and the aqueous solution is acidic with the PH 2.5-5.5 (10 % aqueous solution).
The following equilibriums exists after NaHSO3 dissolved in water:
HSO3- <===> H+ + SO32-
HSO3- + H2O <===> H2SO3 + OH
H2SO3 <===> SO2 + H2O
What’re the Uses of Sodium Bisulfite?
Food
Generally, food grade sodium bisulfite can be used as an antimicrobial agent and antioxidant in food.
Sodium bisulfite releases sulfur dioxide gas when added to water in acidic conditions, which functions as a preservative to kill microorganisms.
Sodium bisulfite can also be used as an oxygen scavenger which reacts with oxygen first and then prevents food spoilage from oxidation.
And thus protects the color (anti-browning), freshness and flavor of food.
Fruits and vegetables
NaHSO3 is commonly used in the preservation of fruits and vegetables by preventing the enzymatic browning effect caused by polyphenol oxidase.
Commonly used in fruit canning and leafy green vegetables.
Shrimp
The shrimp are often treated with sodium bisulfite to prevent or slow down the black spot formation (melanosis) in the head and shell of shrimp after being exposed to oxygen.
Therefore, sodium bisulfite helps keep a good appearance for shrimp.
Cheese
Its function is to prevent the browning caused by Maillard reaction in the manufacturing of processed cheese at high temperatures.
Corn starch
Sodium bisulfite can be used to soften corn kernels, reduce the mechanical strength of corn kernels, and thus enable fiber and protein easily separated from starch.
Sodium bisulfite is an acidic salt, which is more stable than sulfurous acid in an aqueous solution.
Pharmaceuticals
Certain ingredients in some drugs are easily oxidized, and its purpose is used as an antioxidant to improve their stability.
Agriculture
In agriculture, it can be used to increase the photosynthesis rate and therefore increase fruit output.
Spraying sodium bisulfite during the period of fruit growth can increase the chlorophyll content by reducing sulfur to sulfhydryl (-SH), accelerate the photosynthetic rate by inhibiting the activity of glycolate oxidase and reducing the release of carbon dioxide, promote the accumulation of photosynthetic products in the fruit, and thereby increase the fruit weight gain rate.
Industrial
Industrial grade sodium bisulfite is widely used in the bleaching of cotton fabrics, and is also used as a reducing agent in the dye, paper, leather, and some other chemical synthesis.
Water treatment
NaHSO3 can be used as a mild reducing agent for wastewater chlorination.
Sodium bisulfite is used to remove the residual chlorine in wastewater after chlorine has been used for adequate contact time for disinfection.
The following is the reaction mechanism with hypochlorous acid:
2NaHSO3 + 2HOCl –> H2SO4 + 2HCl + Na2SO4
Sodium bisulfite can also be used to remove bromine and iodine.

Sodium Bisulfite is a very valuable and versatile product that plays several key roles throughout the wine making process.
It is used, almost without exception, in all commercially made wines.
Among its many uses are: purifying fresh juices before the fermentation begins; using it in heavier doses with water for sanitizing bottles and equipment as needed; and, adding it to your wine at bottling time to reduce some of the negative effects of storage such as oxidation and deterioration of flavor.
What Is Sodium Bisulfite?
For the sake of keeping this article in layman terms, Sodium Bisulfite is essentially very fine crystallized sodium granules that release sulfur gas when it is dissolved in a liquid.
This sulfur gas permeates the liquid it was added to and then eventually dissipates into the air over the coarse of several hours.
The sulfur gases that are released from the Sodium Bisulfite act as a sanitizer, killing wild molds, bacteria, germs and other unwanted little nasties.
The sulfur gases also help to preserve the wine by displacing any air that may be saturated in the wine.
The sulfur gas is not so strong as to smell up the whole house, but its odor is noticeable when standing next to a liquid that has been treated.
It is important to note here that Sodium Bisulfite is also the active ingredient found in Campden Tablets.
Each Campden Tablet equals 1/16 of a teaspoon of Sodium Bisulfite, or to put it another way, it takes 16 Campden Tablets to equal one teaspoon of Sodium Bisulfite.
So, when we talk about Sodium Bisulfite you can think of it as being interchangeable with Campden Tablets.
Sodium Bisulfite is also interchangeable with Potassium Bisulfite.
It comes in the same crystallized form as Sodium Bisulfite, and the dosage is measured the same.
The main difference is the active sulfur is stabilized in potassium instead of sodium.
Sanitizing Fresh Juices With Sodium Bisulfite
You can add Sodium Bisulfite in lighter doses directly to any fresh wine making juices before fermentation to sanitize them.
These fresh squeezed juices can contain a whole host of contaminating organisms, along with the natural yeast.
These micro-organisms, if allowed to grow, pose a threat to your wine by way of spoilage.
Description
Chemical compound with formula NaHSO3.
Sodium bisulfite releases sulfur dioxide gas when added to water, killing yeast, fungus, and bacteria, roughly 24 hours before fermentation, when added to wines.
It may also be added after fermentation to prevent vinegar production and protect the color and flavor of wine.
It kills microbes and in fruit canning, prevents browning.
The substance is also added to leafy green vegetables to preserve visual freshness of the greens.
There is some debate as to whether high doses of sodium bisulfite can cause allergic reactions in individuals.
Culinary Uses:
Prevention of oxidation.
Preservation of flavor.
Used in home winemaking to prevent oxidation and preserve flavor.
Used to kill microbes in canning applications.
Added to greens to prevent oxidation.
Substitutions
Sodium metabisulfite (available to commercial manufacturers and wine makers in large quantities)
Storage
Be careful handling the substance, as it is known to cause irritation to the nasal, throat, and respiratory tracts. Keep in dry, cool, well ventilated area in a corrosive proof area.
Production
Produced by bubbling sulfur dioxide in a solution of sodium carbonate in water.
