What is the mechanism of action of Potassium Sorbate as a preservative?
Potassium Sorbate dissociates in water to form sorbate ions. The undissociated sorbic acid (pKa 4.76) is the active antimicrobial form — it is most effective at pH below 6.5. Sorbic acid disrupts fungal cell membrane function and inhibits key enzymes in mould and yeast metabolism. It is primarily a fungistatic agent and is most effective against moulds and yeasts, with limited antibacterial activity.
What concentration of Potassium Sorbate is typically used in food products?
FSSAI and Codex Alimentarius specify maximum usage levels. Typical concentrations: bakery products 0.05–0.1% (500–1000 ppm), cheese and dairy products 0.05–0.3%, beverages and juices 0.02–0.05%, wines 0.02–0.03%. Always use at the minimum effective concentration and ensure pH is below 6.5 for best efficacy.
Can Potassium Sorbate be used in cosmetic formulations?
Yes. Potassium Sorbate is increasingly used as a preservative in cosmetic formulations as a safer alternative to parabens. It is effective at 0.1–0.5% in rinse-off products (shampoos, body wash) and 0.1–0.3% in leave-on products (creams, lotions). It works best at pH 4.5–6.0 and is often combined with other preservatives for broader antimicrobial spectrum.
Is Potassium Sorbate safe for consumption and approved in India?
Yes. Potassium Sorbate is approved as a food preservative (FSSAI INS 202) in India and worldwide. It is rapidly metabolised in the body via normal fatty acid oxidation pathways and excreted as CO₂ and water — the same as regular food fats. It has an excellent safety record across decades of worldwide use and is listed as GRAS (Generally Recognised as Safe) by the FDA.
