Potassium sorbate is a salt of sorbic acid and potassium. It is used as a food preservative and stabilizer, with an optimum concentration of 0.1%. It has been shown to be genotoxic in certain studies with Candida glabrata, but not in others. Potassium sorbate has also been shown to inhibit the growth of mold and yeast, while being non-toxic to humans. The analytical method for determining the concentration of potassium sorbate in a sample is based on the reaction between potassium sorbate and p-hydroxybenzoic acid (PHBA). This reaction produces benzoic acid (BA) and water vapor, which are measured by gas chromatography/mass spectroscopy (GC/MS). Potassium sorbate has been shown to have anti-atherosclerotic effects through its ability to inhibit cholesterol synthesis.
