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.

Public awareness regarding artificial additives has been growing, prompting some food manufacturers to reformulate their products. Many brands are now emphasizing clean label products, which use fewer synthetic additives and focus on natural ingredients. This shift underscores a consumer demand for transparency in food labeling and an overall preference for foods that are perceived as healthier and more wholesome.

In the culinary world, sodium bicarbonate is widely recognized for its role as a leavening agent in baking.

Beyond baking, sodium bicarbonate is also used in cooking processes, such as tenderizing meats and neutralizing acidity in various dishes.
