No-Added-Sulfites Wine. Sulfites in wine are chemicals used as preservatives to prevent browning and discoloration in foods and drinks.

Sodium benzoate is a preservative commonly used in fruit pies, jams, beverages, salads, relishes, and sauerkraut -- foods that have an acidic pH. Chemical preservatives, such as sodium benzoate are frequently used in processed foods to prevent the growth of bacteria, yeast or other nasty microorganisms that could spoil your food. When sodium benzoate is combined with water, benzoic acid is produced. Benzoic acid is the active form of the preservative - the form that protects foods. Benzoic acid is also found naturally in some fruits such as cranberries, plums, and apples.
