One of the primary functions of potassium metabisulfite in food preservation is its ability to inhibit the growth of microorganisms, such as bacteria, yeasts, and molds. These microorganisms can cause spoilage, leading to food wastage and potential health risks for consumers. By adding potassium metabisulfite to products like wine, dried fruits, and certain condiments, producers can significantly reduce the likelihood of spoilage, preserving the product for a longer time. In the winemaking industry, for instance, potassium metabisulfite is often added to grape must to prevent premature fermentation and oxidation, ensuring that the final product maintains its desired flavor profile.
