Our company for very different mineral product line (kaolin, manganese dioxide, talc, sepiolite, zeolite, graphite) is producing or has supplied and are one of the leading firms in Turkey on this issue. 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.
