Sorbic acid is used as a preservative in food and beverage production. It is a natural, organic acid that helps prevent the growth of molds, yeasts, and certain bacteria, thereby extending the shelf life of various food products. It is particularly effective in acidic foods like pickles, salad dressings, jams, and carbonated beverages. Sorbic acid works by inhibiting the growth and reproduction of microorganisms, which helps prevent spoilage and maintain the quality of the food or beverage. It is a widely used preservative due to its effectiveness, low cost, and stability.
