Potassium sorbate (E202) is a synthetic food preservative commonly used
to extend the shelf life of various food products.
It works by inhibiting the growth of molds, yeast, and some bacteria,
preventing spoilage. When added to foods, it helps maintain their
freshness and quality.
Some studies have shown that when combined with nitrites, potassium
sorbate have genotoxic activity in vitro. However, potassium sorbate is
generally recognized as safe (GRAS) by regulatory authorities.
