Sodium bisulfite

An antichlor is a substance used to decompose residual hypochlorite or chlorine after chlorine-based bleaching, in grouping to prevent ongoing reactions with, as alive as therefore loss to, the material that has been bleached. Sodium bisulfite is an example of an antichlor. Historically, sodium bisulfite has been used in the textile industry, cosmetic industry, food industry, together with more.

Sodium bisulfite or sodium bisulphite, sodium hydrogen sulfite is a chemical mixture with the approximate chemical formula NaHSO₃. Sodium bisulfite in fact is non a real compound, but a mixture of salts that dissolve in water to administer solutions composed of sodium and bisulfite ions. It occurs as white or yellowish-white crystals with an odor of sulfur dioxide. For properties of sodium bisulfite, refer to the table located to the right. Regardless of its ill-defined nature, sodium bisulfite is used in many different industries such a food additive with E number E222 in the food industry, a reducing agent in the cosmetic industry, and a decomposer of residual hypochlorite used in the bleaching industry.

Sodium Bisulfite in the Food Industry

Similar to the cosmetic industry, the European Commission requested the European Food Safety a body or process by which energy or a particular component enters a system. EFSA to review and determining if the usage of sulfites as food additives was still safe in light of new scientific engineering and information. Since sodium bisulfite is a call sulfonating compound, it underwent the experimentation. Based on clinical experiments using rats and mice, the World Health agency Expert Committee on Food Additives came to the conclusion that 0-0.7mg of sulfur dioxide equivalent/kg of body weight per day will hold no damage to an individual consuming this compound as a food additive. The genotoxicity and carcinogenicity were examined just as in the cosmetic trials and in both cases, no potential for concern with respect to the sulfites were found.

The production of sodium bisulfite used as a food additive can be transmitted by the combination of Monier-Williams type procedure, HPLC after extraction, and Flow Injection analysis. Overall, the ownership of sodium bisulfite in the food industry as an additive and antioxidant is safe and beneficial to the lifespan of processed foods.
