Applications:
- It is used as a food additive and in sanitation as a cleaning agent. Concentrated Sodium Meta Bisulphite is used to remove tree stumps.
- Sodium Meta Bisulfite is encountered occasionally as a food preservative with the combination of sulphur dioxide in sweets and moist foods, especially in the foods that contain coconut flavors.
- Mainly it is used as an excipient in some tablets as paracetamol. A very important health related aspect of this substance is that it can be added to a blood smear in a test for sickle cell anaemia. This substance causes defunct cells to sickle, hence confirming disease.
