Overview
Sodium bisulfite is a white powder that serves a few different functions.
This ingredient is frequently used as a preservative due to its ability to kill a variety of bacteria species. In addition to its antimicrobial properties, sodium bisulfite also serves as a reducing agent. As a result, it can act as an antioxidant by preventing oxidation in the first place due to its chemical nature. Antioxidants are useful for protecting other ingredients that are sensitive to oxidation, which commonly occurs through exposure to ultraviolet light.
The addition of sodium bisulfite allows these vulnerable ingredients to maintain integrity even when exposed to the radiation.
