Key Advantages of Our Potassium Sorbate Granular

Superior Antimicrobial Performance Across pH Ranges

Our product kills a wide range of germs at pH levels between 3.0 and 6.5, which makes it perfect for food systems that are slightly acidic or almost neutral. Unlike sodium benzoate, which only works at low pH levels, this granular protection stops molds, yeasts, and most oxygen bacteria from growing in tough foods like cheese, yogurt, and dried meats.

Clean Label Solution with Zero Flavor Impact

Your buyers want you to be honest. This protection is allowed by FAO/WHO, the EU, and China GB2760, and it breaks down naturally in the body into CO2 and water. It doesn't change the taste of your product at normal doses, so it keeps the original flavor profile. This makes it great for quality clean-label formulas.

Engineered for Industrial Efficiency

The 1.0mm to 3.0mm grainy size has a bulk density of 600–800 g/L and great flow properties. You'll get accurate automatic doses in fast production lines that don't have to deal with clogged bins or feeds. At 20°C, it dissolves in cold water 58.2% of the time, which makes it easy to make a stock solution.

Synergistic Compatibility for Enhanced Protection

To make your antibacterial range wider, mix our Potassium Sorbate Granular with Natamycin, Nisin, or sodium benzoate. By strategically combining, the amount of each protection used is cut down, and the shelf life of meat products, baked goods, drinks, sauces, and pickled veggies is increased.

Proven Cost-Efficiency at Scale

Mass production methods that are well-developed ensure a steady supply of goods with the same standard from batch to batch. This protection can be used in a lot of different types of food, so it can help you meet a wide range of application needs without having to worry about stocking or supply issues.

Frequently Asked Questions

Q: Why does granular form dissolve slightly slower than powder?

A: The smaller surface area means that it dissolves a little more slowly, but you get a lot of benefits in return, like no dust in the air, no caking during storage, and better flow in controlled feeds. The trade-off makes workers safer and increases the speed of production.

Q: Can I use this preservative in high-pH products above 7.0?

A: No, antibacterial action is best at pH levels below 6.5. The success rests on sorbic acid molecules that are not broken apart, which drop as the pH level rises. For neutral or alkaline formulas, you might want to pair it with other stabilizers.

Q: How should I store this product to prevent degradation?

A: Store it in its original, sealed box out of direct sunlight and heat (below 30°C). When stored correctly, the sorbate structure doesn't oxidize, so it stays potent and doesn't turn yellow over the 24-month shelf life.

Q: Is this a direct replacement for Sodium Benzoate?

A: Yes, many manufacturers prefer it due to superior flavor neutrality. However, synergistic combinations of both preservatives are frequently used to widen antimicrobial spectrum and reduce individual dosage requirements.

Q: What quality testing do you perform on each batch?

A: We conduct rigorous HPLC assay testing, moisture analysis, ICP-MS heavy metal screening, particle size distribution analysis, and solution clarity testing. Every batch includes a Certificate of Analysis documenting compliance with FCC and E202 standards.
