Potassium sorbate is widely used as a preservative in the food industry to prevent the growth of mold, yeast, and fungi. It is commonly added to products such as cheese, wine, yogurt, dried meats, and baked goods to extend their shelf life. In beverages like soft drinks and juices, it helps maintain freshness and prevent spoilage. Additionally, it is used in personal care products like creams and lotions to inhibit microbial growth and ensure product stability. Its effectiveness in low concentrations makes it a popular choice for preserving a wide range of consumable and topical items.
