E529, or calcium oxide, is often used in the food industry as an acidity regulator and stabilizer.
Calcium oxide, being an inorganic compound, is not a source of carbohydrates and does not affect blood sugar levels. However, it is not recommended to consume products containing this component in excess, as an excess of calcium in the body can lead to unwanted consequences such as kidney stones or digestive disorders.
Calcium oxide is commonly found in food additives, such as some types of canned vegetables, cheese, calcium-enriched milk, ketchup, and other products.
In moderate amounts, calcium oxide is not considered dangerous.
