Yes, sodium metabisulfite can kill bacteria. It is commonly used as an antimicrobial agent in the food and beverage industry. When dissolved in water, it releases sulfur dioxide (SO2), which has strong antimicrobial properties. This inhibits the growth of bacteria, fungi, and other microorganisms, helping to preserve the freshness and extend the shelf life of various products such as wines, dried fruits, and processed foods. The effectiveness of sodium metabisulfite depends on the concentration used and the specific type of microorganisms it is targeting.
