E553aii - Trisilicate de magnésium

Origin

Magnesium trisilicate is an inorganic salt composed of magnesium oxide and silicon dioxide. It occurs naturally as the mineral sepiolite, but the food-grade additive is typically synthesized. The synthetic production ensures purity and consistency for use in food and pharmaceutical applications. It is a fine, white, odorless powder.

Usage

In the food industry, magnesium trisilicate is primarily used as an anti-caking agent to prevent powdered or granular foods from clumping together. It can also act as a filter aid. Its absorbent properties make it useful in clarifying liquids. It is found in a variety of products, including table salt, powdered milk, spices, and baking mixes. It is also used in antacids due to its ability to neutralize stomach acid.

Side Effects

Magnesium trisilicate is generally considered safe for consumption at levels typically used in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 'not specified,' meaning that, based on available data, the total daily intake of the substance arising from its use at levels necessary to achieve the desired effect and from its acceptable background in food, does not represent a hazard to health. However, excessive consumption of magnesium trisilicate can lead to gastrointestinal issues, such as diarrhea. Individuals with kidney problems should exercise caution, as magnesium can accumulate in the body. There are no significant allergic reactions associated with magnesium trisilicate.

Regulatory Status

Magnesium trisilicate is approved for use as a food additive in many countries, including the United States, the European Union, and Canada. Regulations specify the maximum permitted levels in various food categories. In the EU, it is designated as E553a(ii). The FDA includes it in its list of substances generally recognized as safe (GRAS) when used in accordance with good manufacturing practices.
