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
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.
This is ACS Reagent Grade material with a minimum purity of 99%.
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.
Harmful if ingested or inhaled.
