E329 - Magnesium lactate

Origin

Magnesium lactate is a salt formed by the reaction of magnesium with lactic acid. Lactic acid is a naturally occurring organic acid, produced by fermentation processes in bacteria and also found in animal muscle tissue. The magnesium source is typically magnesium hydroxide or magnesium carbonate. The resulting magnesium lactate is a white to off-white crystalline powder or granules.

Usage

As a food additive, magnesium lactate serves multiple purposes. It is primarily used as an acidity regulator, helping to maintain a desired pH level in food products. It also functions as a firming agent, improving the texture of processed fruits and vegetables. Furthermore, it acts as a nutrient supplement, providing a source of magnesium, an essential mineral. Magnesium lactate is found in a variety of foods, including processed fruits and vegetables, dairy products, and dietary supplements. It is also used in infant formulas to provide magnesium. The levels used are dictated by Good Manufacturing Practice (GMP) and are dependent on the food type and desired effect.

Side Effects

Magnesium lactate is generally considered safe for consumption at levels typically used in food. The European Food Safety Authority (EFSA) has evaluated magnesium lactate and concluded that it does not pose a safety concern at the intended uses and use levels. Excessive intake of magnesium, in general, can lead to gastrointestinal issues such as diarrhea and abdominal cramping. However, these effects are usually associated with much higher doses than those found in food products containing magnesium lactate. There is no established Acceptable Daily Intake (ADI) specifically for magnesium lactate, as magnesium is an essential nutrient, and intake is regulated based on overall magnesium intake from all sources.

Regulatory Status

Magnesium lactate (E329) is approved for use as a food additive in the European Union (EU) under Regulation (EC) No 1333/2008 on food additives. It is also permitted for use in food in other countries, including the United States, where it is Generally Recognized As Safe (GRAS) when used in accordance with good manufacturing practice. The specific regulations and permitted uses may vary depending on the country.
