E343ii - Dimagnesium phosphate

Origin

Dimagnesium phosphate (E343ii) is an inorganic salt composed of magnesium and phosphate. It is produced synthetically by reacting magnesium oxide or magnesium hydroxide with phosphoric acid under controlled conditions. The resulting product is a white, odorless powder or crystalline substance. It is commonly available in hydrated forms.

Usage

In the food industry, dimagnesium phosphate serves multiple functions. It is primarily used as an acidity regulator, buffering agent, and nutrient supplement. It can be found in various food products such as processed cheeses, baked goods, cereals, and powdered beverages. It helps to maintain a stable pH, preventing undesirable changes in taste, texture, and appearance. As a source of magnesium, it contributes to the nutritional value of fortified foods. It also acts as an anti-caking agent in powdered foods. The typical usage levels vary depending on the specific application and food product.

Side Effects

Dimagnesium phosphate is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. Magnesium is an essential mineral, and phosphate is naturally present in the body. However, excessive intake of magnesium can lead to gastrointestinal disturbances such as diarrhea, nausea, and abdominal cramping, particularly in individuals with impaired kidney function. High phosphate intake may also interfere with calcium absorption. The European Food Safety Authority (EFSA) has not established a specific Acceptable Daily Intake (ADI) for dimagnesium phosphate, but it is considered safe at levels typically used in food. Individuals with kidney problems should consult a healthcare professional before consuming large amounts of magnesium or phosphate-containing additives.

Regulatory Status

Dimagnesium phosphate (E343ii) is permitted for use as a food additive in the European Union (EU) under Regulation (EC) No 1333/2008. It is also approved for use in the United States by the Food and Drug Administration (FDA) under specific conditions. The additive must comply with purity criteria specified in relevant regulations to ensure its safety and quality.
