  • Potassium sorbate is a commonly used preservative with antimicrobial properties often used as preservatives in food and drinks to prevent the growth of mold, yeast, and fungi. In general the potassium sorbate is preferred over the sorbic acid because it is more soluble in water, but the active form is the acid. The optimal pH for the antimicrobial activity is below pH 6.5. Sorbates are generally used at concentrations of 0.025% to 0.10%. Adding potassium sorbate to food will, however, raise the pH of the food slightly so the pH may need to be adjusted to assure safety. It is found in foods such as various kinds of cheese, bread, muffins, donuts, pies, cookies, protein bars, syrups, lemonades, fruit juices, dried meats, sausages, nuggets, burgers, sandwiches, tacos, pizzas, smoked fish, margarine, sauces, soups, and more.

As consumers become more health-conscious, understanding food additives like E304 is essential to navigate the complexities of modern diets and food preservation.
