Potassium sorbate is the potassium salt of Sorbic Acid, chemical formula C6H7KO2. Its primary use is as a food preservative.
Potassium sorbate is effective in a variety of applications including food, wine, and personal care products.
Potassium sorbate is produced by reacting Sorbic Acid with an equimolar portion of potassium hydroxide. The resulting potassium sorbate may be crystallized from aqueous ethanol.
Function
1. Food preservatives. It can effectively restrain the mold, yeast anaerobic-Aerobic bacterial activity, such as cheese, wine,
yogurt, dried meats, apple cider, soft drinks and fruit drinks, and baked goods. So as to prolong the shelf life of food and keep the original flavor of food.
2. it is used in many personal care products to inhibit the development of microorganisms for shelf stability.
3. It is primarily used with sweet wines, sparkling wines, and some hard ciders.
