E526 Calcium hydroxide

What is Calcium hydroxide (E526)?

E526, or calcium hydroxide, is a common food additive used as an acidity regulator. It helps control the pH levels in food, ensuring the desired acidity or alkalinity. It is widely used in the food industry for processing corn in tortillas, clarifying sugar, and enhancing the firmness of canned vegetables.

Why do I have an intolerance?

Calcium hydroxide intolerance can arise if your digestive system struggles to process this additive or if you have a sensitivity to calcium compounds. For some individuals, ingestion of foods containing calcium hydroxide may lead to digestive discomfort, including bloating, nausea, or diarrhea. This intolerance could also be linked to an overreaction of your body's immune system, perceiving the additive as harmful.

What can I do about it?

If you experience symptoms of intolerance, you should limit or avoid foods that contain E526. Check ingredient labels for calcium hydroxide or its alternative names. Opt for natural, minimally processed foods that do not contain artificial acidity regulators. Homemade versions of processed foods, such as tortillas or canned vegetables, may allow you to avoid the additive altogether.
