What is Potassium Sorbate?

Potassium sorbate is a potassium salt derived from sorbic acid, a naturally occurring compound found in some berries. It is commonly manufactured through a chemical process that neutralizes sorbic acid with potassium hydroxide, resulting in a stable, odorless, and tasteless powder.

This ingredient is widely used as a preservative in food and drink products to prevent the growth of mold, yeast, and fungi, extending shelf life. While it is considered safe by global food safety authorities, some studies suggest that it may cause mild irritation in sensitive individuals.

When seen on a label, potassium sorbate is typically present in small amounts, and most consumers tolerate it well. Always consider your personal sensitivity and any known allergies.
