Technical Specifications and Properties of Potassium Sorbate

Potassium sorbate (chemical formula: C₆H₇KO₂) is the potassium salt of sorbic acid, a naturally occurring polyunsaturated fatty acid. It is widely regarded as a superior food preservative due to its potent fungistatic properties, effectively inhibiting the growth of molds, yeasts, and many bacteria, thereby extending product shelf-life and ensuring microbial safety.

From a technical perspective, potassium sorbate typically presents as a white to off-white crystalline powder or granules, characterized by a faint, characteristic odor. Its solubility in water is excellent (approximately 58 g/100 mL at 20°C), making it highly suitable for incorporation into aqueous-based food systems, beverages, and cosmetic formulations. The optimum pH range for its antimicrobial efficacy is generally between 3.0 and 6.5, making it particularly effective in acidic and mildly acidic products such as fruit juices, dairy products, wine, and baked goods. Beyond pH 6.5, sorbic acid gradually dissociates into its ionic form, which has significantly reduced antimicrobial activity.

Key parameters that define the quality and performance of potassium sorbate include its assay (purity), moisture content, and heavy metal limits. These specifications are critical for compliance with international food-grade standards such as the Food Chemicals Codex (FCC), European Pharmacopoeia (EP), and monographs from organizations like the Joint FAO/WHO Expert Committee on Food Additives (JECFA). Manufacturers seeking to buy potassium sorbate must prioritize suppliers who provide materials conforming to these rigorous standards to ensure product safety and efficacy.
