Potassium Sorbate
Potassium Sorbate (E202) is the potassium salt of sorbic acid, offering significantly improved water solubility (58g/100mL at 20°C) compared to sorbic acid itself, making it the preferred form for aqueous food preservation applications. It inhibits yeast and mold growth by disrupting the enzymatic function of microbial cell membranes, with broad spectrum efficacy across Aspergillus, Botrytis, and common food spoilage yeasts. It has no meaningful antibacterial activity and is therefore typically combined with sodium benzoate in broad-spectrum preservation systems.

Key Benefits
- High water solubility (58g/100mL) enables direct dissolution into liquid food systems.
- Broad-spectrum antifungal efficacy — effective against Aspergillus, Penicillium, and spoilage yeasts.
- pH-effective range up to 6.5 — broader than sorbic acid in neutral-pH formulations.
- No significant flavor impact at permitted food additive usage levels (<0.2% in most applications).
- Metabolized as a standard fatty acid (beta-oxidation) — considered safe for global regulatory purposes.
