Calcium sorbate is a widely used food preservative that inhibits the growth of mold, yeast, and bacteria. It is commonly used in cheese, wine, and baked products to prevent spoilage and give them a longer shelf life. However, if you are looking for alternatives to this ingredient, there are several synonyms that you can use. Some of the most popular synonyms for calcium sorbate include sorbic acid, potassium sorbate, sodium benzoate, and propionic acid. Sorbic acid is the most commonly used alternative, as it is both effective and affordable. Potassium sorbate is also a good option, especially for pH-sensitive foods, while sodium benzoate may work best for acidic products. Propionic acid works well in bread and baked goods.
