Potassium Sorbate And Calcium Disodium EDTA As Preservatives

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring organic compound. It is typically manufactured synthetically through a chemical process. Calcium disodium EDTA (ethylenediaminetetraacetic acid) is a synthetic chelating agent, meaning it binds to metal ions.

These ingredients are used together as preservatives in a wide variety of processed foods. They work by inhibiting the growth of mold, yeast, and bacteria, which helps extend shelf life. They are commonly found in salad dressings, sauces, marinades, and processed meats.

Potassium sorbate is generally recognized as safe (GRAS) by the FDA. Calcium disodium EDTA is also approved by the FDA for use as a preservative. Both substances have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some studies have explored potential effects of EDTA at very high doses, though these are not typically encountered through food consumption.
