E343i - Monomagnesiumphosphat

Origin

Monomagnesium phosphate is an inorganic salt composed of magnesium and phosphate ions. It is produced synthetically through the reaction of magnesium oxide or magnesium hydroxide with phosphoric acid under controlled conditions. The resulting product is a white, crystalline powder that is soluble in water.

Usage

In the food industry, monomagnesium phosphate serves primarily as a buffering agent, acidity regulator, and nutrient supplement. It is used to control the pH of food products, preventing excessive acidity or alkalinity. As a nutrient supplement, it provides magnesium, an essential mineral involved in numerous physiological processes. It can be found in various processed foods, including baked goods, cereals, dairy products, and beverages. It is also used in animal feed and fertilizers.

Side Effects

Monomagnesium phosphate is generally considered safe for consumption at levels typically used in food. The EFSA (European Food Safety Authority) has established an Acceptable Daily Intake (ADI) for phosphates, including monomagnesium phosphate, when used as food additives. Excessive intake of phosphates, however, may lead to imbalances in mineral metabolism, particularly affecting calcium absorption. Individuals with kidney problems may be more susceptible to adverse effects from high phosphate intake. Symptoms of excessive phosphate intake can include muscle cramps, numbness, tingling, and bone pain. As with any food additive, individuals with specific sensitivities or allergies should exercise caution.

Regulatory Status

Monomagnesium phosphate (E343i) is approved for use as a food additive in the European Union (EU) and is subject to specific purity criteria and usage levels. It is also permitted for use in food in other countries, including the United States, where it is generally recognized as safe (GRAS) under certain conditions of use. Regulations governing its use are established by agencies such as the FDA (Food and Drug Administration) in the US and EFSA in Europe. These regulations specify the maximum permitted levels in various food categories to ensure consumer safety.
