Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH 3 CH=CH−CH=CH−CO 2 K. It is a white salt that is very soluble in water (58.2% at 20 °C). It is primarily used as a food preservative (E number 202). [4] Potassium sorbate is effective in a variety of applications including food, wine, and personal-care products.
Sorbic acid and its salts, especially potassium sorbate and calcium sorbate, are antimicrobial agents often used as preservatives in food and drinks to prevent the growth of mold, yeast, and fungi. In general the salts are preferred over the acid form because they are more soluble in water, but the active form is the acid.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Without the addition of potassium sorbate the yeast population will only be stunned and eventually repopulate if provided with enough fermentable sugars. [ 3 ] A typical Campden tablet contains 0.44 g of sodium metabisulfite, plus filler; eight of these are equivalent to one-half level teaspoon (2.5 mL) of sodium metabisulfite.
Potassium sulfate (US) or potassium sulphate (UK), also called sulphate of potash (SOP), arcanite, or archaically potash of sulfur, is the inorganic compound with formula K 2 SO 4, a white water-soluble solid.

It's an excellent source of high-quality, lean protein that’s packed with essential vitamins and minerals, including zinc, selenium, potassium, B vitamins and more.
In wine, it is often used to replace potassium sorbate, as it inactivates wine spoilage yeasts such as Brettanomyces. Once it has been added to beverages, the efficacy of the chemical is provided by the following reactions: DMDC + water → methanol + carbon dioxide DMDC + ethanol → ethyl methyl carbonate DMDC + ammonia → methyl carbamate
