E509 Calcium chloride

What is Calcium chloride (E509)?

E509, or calcium chloride, is used as an anti-caking agent and acidity regulator in foods. It helps maintain the texture and consistency of certain products, preventing them from clumping or becoming too moist. Calcium chloride is commonly found in canned vegetables, dairy products, and beverages like sports drinks. It also plays a role in firming food textures, such as in pickles and tofu.


Why do I have an intolerance?

Intolerance to calcium chloride may result from its potential to irritate the digestive system. In some cases, high concentrations of calcium chloride can lead to symptoms such as stomach pain, nausea, or bloating. If your digestive system is particularly sensitive to calcium-based additives, you may experience discomfort after consuming foods containing E509.


What can I do about it?

If you have an intolerance to E509, avoiding processed foods that list calcium chloride as an ingredient is key. Focus on fresh, natural foods that don’t require anti-caking agents or preservatives. Increasing your intake of foods naturally rich in calcium, like leafy greens and dairy products, can ensure you maintain balanced calcium levels without relying on additives.
