Detailed Product Description:

Sodium Bisulfite (sometimes called sodium hydrogen sulfite) is a

chemical compound often used as a food additive.  It is prepared

by bubbling sulfur dioxide through a solution of sodium carbonate

in water.

 

Sodium Bisulfite comes in the form of very fine crystallized sodium

granules that, when dissolved in a liquid containing water, release

sulfur dioxide gas.  This gas permeates the liquid and then diffuses

into the air.  This gas acts as a sanitizer, killing molds, fungus, and

bacteria.   The gas is not so strong as to be overwhelming but its

odor is noticeable.

 

In its most common form it is usually found in a mixture that

also contains sodium metabisulfite.

 

Grade/Purity:

This is ACS Reagent Grade material with a minimum purity of 99%.

 

Applications:

Commonly used as a reducing agent, in fermentation, as an

antiseptic, and in copper and brass plating.

 

Sodium bisulfite is used in almost all commercial wines, to prevent

oxidation and preserve flavor.  It releases sulfur dioxide gas when added

to water or products containing water.  The sulfur dioxide kills yeasts,

fungi, and bacteria in the grape juice before fermentation.  When the sulfur

dioxide levels have subsided (about 24 hours), fresh yeast is added for

fermentation.  It is later added to bottled wine to prevent oxidation (which

makes vinegar), and to protect the color of the wine from oxidation, which

causes browning.  The sulfur dioxide displaces oxygen in the bottle and

also dissolved in the wine, preventing it from turning orange or brown, and

taste like raisins or cough syrup.

 

Precautions:

Harmful if ingested or inhaled.
