E542 - Bone phosphate

Origin

Bone phosphate, also known as bone ash or bone char, is derived from animal bones, typically bovine (cattle) bones. The bones are heated to high temperatures in a controlled process called calcination. This process removes organic matter and water, leaving behind a mineral residue primarily composed of calcium phosphate, specifically hydroxyapatite. The resulting material is then processed and purified for use as a food additive.

Usage

E542 is used in the food industry as an anti-caking agent, a clarifying agent, and a source of calcium and phosphate. It can be found in products like sugar refining (to decolorize sugar solutions), dietary supplements, and some processed foods. Bone phosphate helps to improve the texture and stability of certain food products. It is also used in the production of fine bone china and other non-food applications.

Side Effects

Bone phosphate is generally considered safe for consumption in the amounts typically used in food. Calcium and phosphate are essential minerals for human health. However, excessive intake of phosphates can potentially lead to imbalances in mineral metabolism, particularly in individuals with kidney problems. There is no established Acceptable Daily Intake (ADI) specifically for E542, but the intake of phosphate from all sources should be considered. Individuals with specific dietary restrictions or health concerns should consult with a healthcare professional.

Regulatory Status

Bone phosphate is permitted for use as a food additive in several countries, including those within the European Union. Its use is regulated to ensure that it meets purity standards and is used within specified limits in certain food categories. Regulations vary by country, so it's important to check local guidelines. The additive must meet specific purity criteria to ensure it does not contain harmful contaminants.
