Potassium Sorbate And Citric Acid Added As Preservatives

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring organic compound. It is typically produced industrially through the neutralization of sorbic acid with potassium hydroxide. Citric acid is a weak organic acid found naturally in citrus fruits and is also produced commercially through microbial fermentation.

Potassium sorbate and citric acid are often used together as preservatives in packaged foods. Potassium sorbate inhibits the growth of mold, yeast, and some bacteria, while citric acid enhances the effectiveness of potassium sorbate and also acts as an antioxidant and flavor enhancer. They are commonly found in baked goods, dairy products, beverages, and processed fruits and vegetables.

Potassium sorbate is generally recognized as safe (GRAS) by the FDA for use as a food preservative. Citric acid is also GRAS. Both substances have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some individuals may experience mild allergic reactions or sensitivities, though this is rare. Evidence on long-term health effects at high doses is limited.
