E529

E529 is the European Union's E number designation for calcium sulfate. Calcium sulfate is an inorganic salt with the chemical formula CaSO4. It occurs naturally as the mineral gypsum and is also known as plaster of Paris or anhydrite depending on its hydration state. In its food additive form, it is a white crystalline powder.

As a food additive, E529 is used for a variety of purposes. It functions as a firming agent, helping to maintain the texture of fruits and vegetables during processing and canning. It also acts as a dough conditioner, improving the workability of dough in baked goods. Additionally, it can be used as a drying agent, absorbing moisture from food products. E529 is permitted in a wide range of food categories, including bakery products, dairy products, processed fruits and vegetables, and confectioneries.

The safety of calcium sulfate as a food additive has been evaluated by regulatory bodies like the European Food Safety Authority (EFSA). It is generally recognized as safe (GRAS) when used within specified limits. It is not associated with any significant adverse health effects and is not thought to be allergenic or toxic. The acceptable daily intake (ADI) has not been established, indicating that it is considered to pose no safety concerns at typical consumption levels.
