What is Sodium Bisulfite E222

Additive E222 is a food preservative commonly known as sodium bisulfite. It is used in the food industry to prevent the growth of bacteria and fungi, thus extending the shelf life of food. This additive is an inorganic compound that comes in the form of white crystals or powder. It has a strong sulfur dioxide odor and dissolves easily in water. Sodium bisulfite is especially used in the preservation of fruits and vegetables, as well as in the production of wines and beers. It acts as an antimicrobial agent, preventing deterioration and decomposition of food products. However, the E222 additive may cause allergic reactions in some people, especially those who are sensitive to sulfur dioxide. These reactions can include symptoms such as difficulty breathing, hives, itchy skin, redness, and swelling. It is important to note that this additive may have restrictions on its use in some countries, due to its possible adverse health effects. It is recommended to read food labels and, if in doubt, consult a specialist. In summary, the additive E222 or sodium bisulfite is a preservative used in the food industry to prevent the growth of bacteria and fungi. Although it can prolong the shelf life of food, it can also cause allergic reactions in some people. It is important to use and consume these foods with caution and moderation.

How do you get Sodium Bisulfite or E222?

The additive E222, also known as sodium bisulfite, is obtained through a chemical process. Below are the general steps to obtain the additive E222

Obtaining sulfur dioxide (SO2) Sulfur dioxide is a gas that can be obtained from the combustion of sulfur elemental (S), or, through chemical reactions with substances that contain sulfur, such as, for example, metal sulfides or minerals that contain it.

Absorption of sulfur dioxide in a solution of sodium hydroxide (NaOH) sulfur dioxide is passed through an aqueous solution of sodium hydroxide. In this process, sulfur dioxide reacts with sodium hydroxide to form sodium sulfite (Na2SO3).

Oxidation of sodium sulfite Sodium sulfite can be oxidized using strong oxidizing agents, such as chlorine dioxide (ClO2), hydrogen peroxide (H2O2) or sodium chlorate (NaClO3). These oxidizing agents convert sodium sulfite to sodium bisulfite (NaHSO3), which is the chemical compound used as additive E222. It is important to note that these steps are a general description of the production process, but there may be differences in the details of the process, depending on the specific methods used by sodium bisulfite manufacturers. In addition, it is important to remember that the E222 additive can have several uses, and it is essential to investigate and comply with the particular rules and regulations of each country in relation to its use and safety in food and beverages.
