WebIn the presence of water droplets, in the form of fog, clouds, rain or hygroscopic aerosols, sulfur dioxide dissolves, so that aqueous-phase oxidation can give rise to bisulfite and sulfite. These equilibria are sensitive to pH, and HSO 3-is the predominant species over the pH range of 2–7.
WebSodium bisulfite is used in almost all commercial wines, to prevent oxidation and preserve flavor. In fruit canning, sodium bisulfite is used to prevent browning (caused by oxidation) and to kill microbes. In the case of wine making, Sodium bisulfite releases sulfur dioxide gas when added to water or products containing water. c string echoWebAntioxidants help to prevent oxidation of products which is a natural process that occurs when oxygen takes electrons from the ingredients in the formulation, changing their composition and efficacy.
