E450vi - Dicalcium diphosphate

Origin

Dicalcium diphosphate, also known as dicalcium pyrophosphate, is an inorganic salt composed of calcium and pyrophosphate ions. It is synthetically produced by reacting calcium salts with pyrophosphoric acid or its salts. The resulting product is a white, odorless powder that is relatively insoluble in water.

Usage

Dicalcium diphosphate is primarily used in the food industry as a buffering agent, leavening agent, and sequestrant. As a buffering agent, it helps to maintain a stable pH in food products. As a leavening agent, it reacts with baking soda to release carbon dioxide, which helps baked goods rise. It is commonly found in baked goods, processed meats, and dental products. In dental products, it acts as a polishing agent. Dicalcium diphosphate is also used in animal feed and fertilizers. The typical usage levels in food vary depending on the application, but it is generally used in relatively small amounts to achieve the desired effect.

Side Effects

Dicalcium diphosphate is generally recognized as safe (GRAS) by regulatory agencies when used in accordance with good manufacturing practices. There is no established ADI (Acceptable Daily Intake) for dicalcium diphosphate, indicating a low level of concern for adverse health effects at typical consumption levels. However, excessive consumption of phosphates can potentially disrupt calcium metabolism and lead to imbalances in mineral levels, particularly in individuals with kidney problems. Individuals with pre-existing kidney conditions should exercise caution. Allergic reactions are rare but possible. No significant side effects have been reported in the scientific literature at normal usage levels in food.

Regulatory Status

Dicalcium diphosphate (E450vi) is approved for use as a food additive in many countries, including those in the European Union and the United States. In the EU, it is subject to specific purity criteria and labeling requirements. In the United States, it is regulated by the Food and Drug Administration (FDA) under the GRAS (Generally Recognized as Safe) status. The FDA specifies conditions of safe use, including limitations on the amount that can be added to food. The additive must also comply with the specifications outlined in the Food Chemicals Codex (FCC).
