Areas of Use:

Sodium metabisulfite is an inorganic salt substance. It is also known as disodium or sodium pyrosulfite. Under normal conditions, sodium metabisulfite, which is in solid form, has a general appearance of yellowish powder or white. Sodium metabisulfite, which can melt at 150 degrees Celsius, has been used for food preservation for many years. Sodium metabisulfite does not cause any harm to the human body when consumed with food. For this reason, its use as an additive in foods has been permitted 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 acids or toxic substances. When sodium metabisulfite is mixed with water, a strong odor occurs. This odor can make it difficult for people with respiratory problems or asthma to breathe. It can also cause gastric irritation in those with allergic disorders. Since sodium metabisulfite is used not only in the food sector but also in cleaning and bleaching products such as wool and jute; it is useful for those who are allergic to this substance to check before using such products.
