E343 - Magnesium phosphates

Origin

Magnesium phosphates (E343) are inorganic salts composed of magnesium and phosphate ions. They are typically produced by reacting magnesium oxide or magnesium hydroxide with phosphoric acid. Different forms exist, including monomagnesium phosphate, dimagnesium phosphate, and trimagnesium phosphate, each with varying ratios of magnesium to phosphate.

Usage

Magnesium phosphates are used in the food industry as acidity regulators, anti-caking agents, and stabilizers. They can also serve as a source of magnesium, an essential mineral. In baked goods, they can improve texture and leavening. They are found in powdered foods to prevent clumping and in processed cheeses to maintain a smooth consistency. They are also used in dietary supplements to increase magnesium content. The specific application depends on the particular form of magnesium phosphate used.

Side Effects

Magnesium phosphates are generally considered safe for consumption at levels typically used in food. The EFSA (European Food Safety Authority) has evaluated magnesium phosphates and concluded that they do not pose a significant health risk at the levels used in food. Excessive intake of magnesium, in general, can lead to gastrointestinal issues such as diarrhea, nausea, and abdominal cramping. However, these effects are more likely to occur with high doses from supplements rather than from food additives. No ADI (Acceptable Daily Intake) has been specifically set for magnesium phosphates as a food additive, as magnesium is an essential nutrient.

Regulatory Status

Magnesium phosphates (E343) are permitted for use as a food additive in the European Union under Regulation (EC) No 1333/2008. The FDA (Food and Drug Administration) in the United States also recognizes magnesium phosphates as GRAS (Generally Recognized As Safe) for use in food under certain conditions. The specific regulations and permitted uses may vary depending on the country and the specific food product.
