E529 Calcium oxide

What is Calcium oxide (E529)?

E529, or calcium oxide, is additive used as an acidity regulator in the food industry. It is known for its role in balancing pH levels in certain food products. Additionally, calcium oxide is used in the preparation of baking powders, self-raising flour, and some processed meats.


Why do I have an intolerance?

Intolerance to calcium oxide can develop if your digestive system is unable to efficiently break down this additive. Symptoms may include stomach discomfort, diarrhea, or nausea. The intolerance may stem from a heightened sensitivity to calcium-based compounds or a difficulty metabolizing certain chemicals used in food additives.


What can I do about it?

To manage your intolerance, it’s important to carefully read ingredient labels and avoid foods containing E529. Focus on eating fresh and natural foods without synthetic acidity regulators. Homemade meals allow you to control the ingredients and avoid food additives that may trigger discomfort. Experimenting with different recipes may help you find safe alternatives to store-bought products.
