E543 - E543 food additive

Origin

Sodium aluminium phosphate (SALP) is an inorganic salt composed of sodium, aluminium, and phosphate ions. It is synthetically produced through a chemical reaction involving sodium hydroxide, aluminium hydroxide, and phosphoric acid. The resulting product is a white, odorless powder.

Usage

SALP functions primarily as a leavening agent in baked goods. It reacts with baking soda (sodium bicarbonate) to release carbon dioxide gas, which causes dough to rise. SALP provides a controlled and consistent release of gas, resulting in a uniform texture in cakes, muffins, and other baked products. It is often used in combination with other leavening agents. SALP is also used as an emulsifier and stabilizer in processed cheese products, preventing separation of fat and water. The acceptable daily intake (ADI) for aluminium from all sources, including food additives like SALP, is set by regulatory bodies such as EFSA and JECFA. It's crucial to monitor overall aluminium intake to remain within safe limits.

Side Effects

The primary concern associated with SALP is the potential for aluminium exposure. Excessive aluminium intake has been linked to neurotoxicity and bone disorders, particularly in individuals with impaired kidney function. Regulatory bodies have established ADI values to minimize the risk of adverse effects. While SALP is generally considered safe when used within permitted levels, individuals with kidney problems should be mindful of their overall aluminium intake from various sources. Some studies suggest a possible link between high aluminium exposure and cognitive decline, but more research is needed to confirm these findings.

Regulatory Status

Sodium aluminium phosphate is approved for use as a food additive in many countries, including the United States, Canada, and the European Union. However, its use is subject to specific regulations and limitations. In the EU, it is regulated under Regulation (EC) No 1333/2008 on food additives. The FDA in the United States also regulates its use under specific CFR (Code of Federal Regulations) sections. These regulations specify the maximum permitted levels of SALP in various food products to ensure consumer safety. Regular monitoring and risk assessments are conducted by regulatory agencies to evaluate the safety of SALP and update regulations as needed.
