Preservative 202 Side Effects

Potassium sorbate (preservative 202) can potentially cause some side effects in sensitive individuals, though reactions are generally rare:

• Allergic reactions like rashes, hives, swelling, itching, or tingling in the mouth

• Skin irritation when used in personal care products

• Nausea and diarrhea

• Nutrient loss in foods

However, potassium sorbate is considered safe by food safety authorities like the FDA and is approved for use as a preservative in many countries. It is used in small amounts to prevent spoilage by microbes in foods like wine, cheese, baked goods, and processed meats.

Severe allergic reactions requiring medical attention are very uncommon. If you experience any signs of an allergic reaction after consuming potassium sorbate, stop eating the product and consult a doctor, especially if symptoms like facial swelling or trouble breathing occur.

To minimize exposure, read food labels, limit intake of highly processed foods, and opt for homemade foods when possible. But overall, potassium sorbate is a well-studied and widely used preservative that is safe for most people.
