In fruit canning, sodium bisulfite is used to prevent browning (caused by oxidation) and to kill microbes. The sulfur dioxide released by these salts kills yeasts, fungi, and bacteria in the grape juice before fermentation. Once the levels of sulfur dioxide have subsided (about 24 hours), fresh yeast is added for fermentation.
The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used. Sulfites are substances that naturally occur in some foods and the human body. They are also used as regulated food additives. [2] When in food or drink, sulfites are often lumped together with sulfur dioxide. [3]
High-dose fish oil supplements are even available by prescription to reduce high triglycerides—fats that circulate in the bloodstream and increase heart disease and stroke risk.
Another use of bisulfite in organic chemistry is as a mild reducing agent, for example to remove traces or excess amounts of chlorine, bromine, iodine, hypochlorite salts, osmate esters, chromium trioxide and potassium permanganate. Sodium bisulfite is a decoloration agent in purification procedures because it reduces strongly coloured ...
Most health claims on fish oil supplements are unfounded A 2023 study analyzed the labels of more than 2,800 fish oil supplements and found that 2,082 — nearly 74% — made at least one health ...
For people without heart issues, regular use of fish oil supplements was associated with a 13% higher risk of developing atrial fibrillation and a 5% heightened risk of having a stroke, according ...
The vitamins biotin and thiamine, as well as lipoic acid contain sulfur heterocycles. Glutathione is the primary intracellular antioxidant. [6] Penicillin and cephalosporin are life-saving antibiotics, derived from fungi. Gliotoxin is a sulfur-containing mycotoxin produced by several species of fungi under investigation as an antiviral agent.
Although the equilibrium lies far to the left, evaporation of a bisulfite salt will produce a substantial amount of disulfite. [6] Disulfite is the conjugate base of disulfurous acid (pyrosulfurous acid), which originates from sulfurous acid in accordance with the dehydration reaction above: 2 H 2 SO 3 → 2 HSO − 3 + 2 H + → H 2 S 2 O 5 ...
