Potassium sorbate is a food preservative that is widely used to inhibit the growth of microorganisms and prevent spoilage in various food and beverage products. It is the potassium salt of sorbic acid, a naturally occurring organic compound.
Potassium sorbate is often used in processed foods, such as baked goods, dairy products, sauces, dressings, and beverages, to inhibit the growth of microorganisms and prevent spoilage.
It is commonly used in winemaking and brewing to prevent the growth of yeast and mold, ensuring the stability and freshness of the final product.
Potassium sorbate can be found in various fruit and vegetable products, including jams, jellies, fruit juices, and dried fruits, to maintain their quality and inhibit microbial growth.
It is used in cheese manufacturing to prevent the growth of yeasts and molds, which can cause spoilage and affect product quality.
Potassium sorbate is added to salad dressings, sauces, and condiments to prevent spoilage and maintain product freshness.
It is used as a preservative in carbonated drinks and soft drinks to inhibit the growth of yeasts, molds, and bacteria.
Potassium sorbate can be found in various cosmetic and personal care products, such as creams, lotions, shampoos, and liquid soaps, to prevent the growth of microorganisms and increase product shelf life.
