Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite is not a real compound, [ 2 ] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
Sulfites used in food processing (but not as a preservative) are required to be listed if they are not incidental additives (21 CFR 101.100(a)(3)), and if there are more than 10 ppm in the finished product (21 CFR 101.100(a)(4)) On July 8, 1986, sodium bisulfite (and other sulfites : "The chemicals affected by the order are sulfur dioxide ...
Sulfites are used as a food preservative or enhancer. They may come in various forms, such as: [5] Sulfur dioxide, which is not a sulfite, but a closely related chemical oxide; Potassium bisulfite or potassium metabisulfite; Sodium bisulfite, sodium metabisulfite or sodium sulfite
Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na 2 S 2 O 5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent. [2] When dissolved in water it forms ...
Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4.Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).
Common antimicrobial preservatives include nisin, sorbates, calcium propionate, sodium nitrate/nitrite, sulfites (sulfur dioxide, sodium bisulfite, potassium hydrogen sulfite, etc.), EDTA, hinokitiol, and ε-polylysine. Antioxidants include tocopherols (Vitamin E), butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT).
For example, a 1-cup serving of a low-sodium vegetable soup contains 549 milligrams of potassium (12% of the Daily Value). Related: What Happens to Your Body When You Eat Potassium.
Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3. A white, water-soluble solid, it is used commercially as an antioxidant and preservative. It is also suitable for the softening of lignin in the pulping and refining processes of wood and lignocellulosic materials. [1]
