Description

Sodium Sorbate is the sodium salt of sorbic acid, a highly effective and widely used food-grade preservative. Its primary value lies in its ability to inhibit the growth of molds, yeasts, and select bacteria, thereby extending the shelf life of a vast range of perishable products. This makes it an essential ingredient for manufacturers in the food and beverage, pharmaceutical, and personal care industries seeking safe and reliable preservation solutions.

Application

• Food & Beverage Preservation: Extensively used in baked goods (cakes, pastries, pies), dairy products (cheeses, yogurts), processed meats, dried fruits, fruit juices, wines, and soft drinks to prevent spoilage.
• Pharmaceutical & Cosmetic Formulations: Acts as a preservative in syrups, creams, lotions, and topical ointments to maintain product integrity and safety throughout their shelf life.
• Animal Feed Additive: Incorporated into feed to prevent fungal growth and mycotoxin formation, ensuring feed quality and safety for livestock.
• Personal Care Products: Used in items like shampoos, conditioners, and skin creams to protect against microbial contamination.
• Industrial Applications: Finds use in adhesives, latex, and other water-based systems as a biocide to prevent microbial degradation.
