    Brief Overview

    Potassium sorbate, with the chemical formula CH3CH=CH−CH=CH−CO2K, is the potassium salt of sorbic acid. This white salt exhibits high water solubility (58.2% at 20°C) and is predominantly employed as a food preservative, designated as E number 202. Recognized for its novelty, high efficiency, safety, and non-toxic properties, potassium sorbate serves as an alternative to traditional preservatives like benzoic acid.

    Manufacturing Process

    Potassium sorbate is an artificially created component formed through the reaction of sorbic acid with potassium hydroxide. While it can be sourced from natural origins like Rowan berries (Sorbus aucuparia), the majority of global supply comes from more environmentally sustainable synthetic processes.

    Food Industry

    Potassium sorbate serves as a mold and yeast inhibitor in various food items, including cheese, wine, yogurt, dried meats, apple cider, soft drinks, fruit drinks, and baked goods. It is a common ingredient in the production of many dried fruit products, while herbal dietary supplements often incorporate potassium sorbate to deter mold and microbes, extending shelf life. Referred to as a "wine stabilizer," it generates sorbic acid when introduced to wine.


    In cosmetics, potassium sorbate finds application in the formulation of facial and eye makeup, as well as personal skin-care and hair products.
