Despite its widespread use and several benefits, the safety and regulatory status of E1450 remain of paramount importance. In many regions, including the European Union and the United States, E1450 is deemed safe for consumption when used within specified limits. Regulatory bodies evaluate food additives for potential risks, ensuring that consumers are protected from harmful effects. Nevertheless, as with any food additive, some individuals may be sensitive or allergic to specific components, so transparency and labeling are crucial for consumer safety.
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.
