Potassium Sorbate

Description

Potassium sorbate is a widely used food and cosmetic preservative, specifically the potassium salt of sorbic acid. It’s a white, odorless, and crystalline powder that effectively inhibits the growth of mold, yeast, and certain bacteria, thereby extending the shelf life of products. While it can be naturally derived, most potassium sorbate is produced synthetically.
Key properties and uses:
Preservative:
Potassium sorbate’s primary function is to prevent spoilage by inhibiting microbial growth in various products.
Food Industry:
It’s commonly used in foods like cheese, wine, yogurt, dried meats, and baked goods to prevent mold and yeast development.
Cosmetics:
In cosmetics, it’s used as a preservative to maintain product stability and safety.
Effectiveness:
Potassium sorbate is most effective at a pH below 6.5, and its activity is enhanced when used in conjunction with other preservatives like sodium benzoate
