Sodium metabisulfite is an inorganic salt substance. It is also known as disodium or sodium pyrosulfite. The general appearance of sodium metabisulphite, which is solid under normal conditions, is yellowish powdery or white. Sodium metabisulfite, which can melt at 150 degrees Celsius, has been used for food preservation for many years. Sodium metabisulphite does not cause any harm to the human body when consumed with food. Therefore, it has been allowed to be used as an additive in foods in many countries, especially in the USA. Sodium metabisulfite should be stored in dry and cool places. Contact with air should be avoided. It should also be kept away from acid or toxic substances. When sodium metabisulfite is mixed with water, a heavy odor emerges. This smell can make it difficult for people with respiratory problems or asthma to breathe. In addition, it may cause gastric irritation in those with allergic conditions. Since sodium metabisulfite is used not only in the food industry, but also in cleaning and bleaching products such as wool and jute; It is beneficial for those who are allergic to this substance to check before using such products.

Sodium Metabisul fiteSodium BisulfiteAsk for PriceSodium metabisulfite, also called Sodium Pyrosulfite or Disodium, is an inorganic compound composed of sodium, sulfur and oxygen.
Its chemical formula is Na2S2O5. It typically comes in a white or yellowish-white crystalline powder. It easily dissolves in water. The substance is sometimes referred to as disodium (metabisulphite). It is used as a disinfectant,antioxidant and preservative agent."
Many chemical properties of Sodium Metabisulphite or sodium pyrosulfite make it a versatile compound useful in many applications. It can eliminate dissolved oxygen in waste water and in pipes. It functions as a bleaching agent, which is useful in making paper pulp, cotton and wool. It is used in water treatment plants to remove excess chlorine. In beer and wine manufacturing, SodiumMetabisulphite or sodium pyrosulfite checmicals are often used to sterilize the equipment.
Sodium metabisulphite or sodium pyrosulfite is used as a food preservative. It is commonly used as a food preservative for dried foods, like potato chips, raisins and apples, as well as fruit concentrate juices. It acts as an antimicrobial, inhibiting the growth of fungi and bacteria, thereby keeping food fresh and saf
