Sodium metabisulfite (Na2S2O5) is an inorganic compound, which is white or yellow crystal with a strong pungent smell. It is soluble in water and the aqueous solution is acidic. When it comes in contact with strong acid, it releases sulfur dioxide and generates corresponding salts. If left in the air for a long time, it will be oxidized into sodium sulfate, so sodium metabisulfite cannot be stored for a long time.

Product Notes
Safe dosage: The dosage of sodium metabisulfite needs to be strictly controlled, generally 10-1000mg/kg. Exceeding this range may have harmful effects on the human body.
Protective measures: Protective equipment, such as gloves, masks and goggles, should be worn during operation to avoid direct contact.
Avoid mixing: It should not be mixed with certain foods or chemicals, especially foods rich in vitamin C, to avoid destroying the nutritional content.
Storage conditions: should be stored in a dry, ventilated and cool place, avoid high temperature and humidity, and keep sealed to prevent moisture absorption and caking.
Avoid long-term storage: Because it is easy to deteriorate, long-term storage is not recommended.
