Potassium Sorbate


Potassium sorbate is mainly used as a food preservative.



Potassium sorbate is mainly used as a food preservative. It is widely used because it has a very strong inhibitory effect on mold and spoilage bacteria, and is easily soluble in water.

Potassium sorbate has been recommended by the United Nations Food and Agriculture Organization as a safe and efficient food preservative. Potassium sorbate has the characteristics of low toxicity, good anti-mildew effect, does not change the original properties of food, easy to use, and has a wide range of applications. Therefore, many foreign developed countries have used potassium sorbate as a good and efficient preservative, which is widely used in food.

Functions and Applications

1.It is used for Yogurt, Cheese, Wine, Dips, Pickles, Dried meats, Soft drinks, Baked goods, Ice cream

Potassium sorbate is used as a preservative in a number of foods, since its anti-microbial properties stop the growth and spread of harmful bacteria and molds. It is used in cheese, baked goods, syrups and jams. It is also used as a preservative for dehydrated foods like jerky and dried fruit, as it does not leave an aftertaste. The use of potassium sorbate increases the shelf life of foods, so many dietary supplements also include it. It is commonly used in wine production because it stops the yeast from continuing to ferment in the bottles."

2.It is used for Food Preservative

Potassium sorbate is used particularly in foods that are stored at room temperature or that are precooked, such as canned fruits and vegetables, canned fish, dried meat, and desserts. It’s also commonly used in food that is prone to mold growth, such as dairy products like cheese, yogurt, and ice cream. Many foods that are not fresh rely on potassium sorbate and other preservatives to keep them from spoiling. In general, potassium sorbate in food is very common.

3.It is used for Winemaking

Potassium sorbate is also commonly used in winemaking, to prevent wine from losing its flavor. Without a preservative, the fermentation process in wine would continue and cause the flavor to change. Soft drinks, juices, and sodas also often use potassium sorbate as a preservative.

4.It is used for Beauty Products

While the chemical is common in food, there are many other potassium sorbate uses. Many beauty products are also prone to mold growth and use the preservative to extend the life of skin and haircare products. It is very likely that your shampoo, hair spray, or skin cream contains potassium sorbate.
