Things worth knowing about "E343"
E343 refers to magnesium phosphates, which are approved food additives used as acidity regulators, anti-caking agents, and stabilizers in various food products.
What is E343?
E343 is the European approval number for magnesium phosphates, a group of salts formed from phosphoric acid and magnesium. They are used in the food industry as multi-functional additives. The designation E343 covers several compounds, including monomagnesium phosphate (E343i), dimagnesium phosphate (E343ii), and trimagnesium phosphate (E343iii).
Technological Functions
Magnesium phosphates serve several technological purposes in food products:
- Acidity regulator: They help stabilize and control the pH level of food products.
- Anti-caking agent: They prevent powdered or granulated foods from clumping together.
- Stabilizer: They improve the consistency and shelf life of products.
- Emulsifier: In certain applications, they support the uniform distribution of ingredients.
Occurrence in Food Products
E343 is used in various food categories, including:
- Powdered foods and instant products
- Dietary supplements
- Baking powder and baking aids
- Spice mixes and table salt
- Dietetic foods
Safety and Approval
E343 is approved in the European Union under Regulation (EC) No. 1333/2008 on food additives. The European Food Safety Authority (EFSA) has evaluated magnesium phosphates and classified them as safe when used within specified quantities. The acceptable daily intake (ADI) has been set as not specified, meaning that at normal intake levels through food, no health risk is expected.
Magnesium as a Nutrient
When consumed, magnesium phosphates provide both magnesium and phosphorus – both essential minerals for the human body. Magnesium is important for muscle and nerve function, bone health, and energy metabolism. Phosphorus is critical for the formation of bones and teeth, as well as energy metabolism. At normal usage levels as a food additive, no adverse health effects are expected in a balanced diet.
Tolerability and Notes
E343 is well tolerated by most people. However, individuals with impaired kidney function should generally discuss increased phosphate intake with their physician, as the kidneys are responsible for excreting excess phosphate. Excessively high magnesium intake may cause gastrointestinal symptoms such as diarrhea.
