Potassium Sorbate

Potassium sorbate is the potassium salt of sorbic acid, an unsaturated fatty acid, supplied by Nustras as white granules or powder and a widely used preservative in the food, beverage, cosmetic and pharmaceutical industries. It is readily water-soluble and inhibits the growth of moulds, yeasts and some bacteria in acidic to mildly acidic products.

It is formulated into beverages, wine and cider, dairy products, baked goods, dried fruit, sauces, dressings and pickles, and into liquid supplements, syrups, gummies, cosmetic products and pharmaceutical preparations where a water-soluble preservative is declared.

The material is a white granule or powder with CAS number 24634-61-5, molecular formula C6H7KO2 and molecular weight 150.2. Assay is standardised to specification and determined by titration, with identity confirmed by the compendial tests for potassium and sorbate and loss on drying controlled to specification; heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies potassium sorbate in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Potassium sorbate (E202) is an accepted food additive and preservative in major markets; buyers confirm the permitted use and maximum level for their application.
