E555 Potassium aluminium silicate

What is Potassium aluminium silicate (E555)?

Potassium aluminium silicate (E555) is a synthetic food additive used primarily as an anti-caking agent and a pigment carrier. It is found in powdered products such as spices, sugar, and processed snacks. This compound helps maintain the texture of powdered ingredients by absorbing moisture and preventing them from clumping together.


Why do I have an intolerance?

Intolerance to potassium aluminium silicate may stem from sensitivity to the aluminium or silicate compounds it contains. Individuals who experience intolerance might notice symptoms such as bloating, nausea, or mild gastrointestinal upset after consuming foods with E555. The body's difficulty in processing these mineral compounds could contribute to the intolerance.


What can I do about it?

If you are intolerant to E555, avoid foods that list this additive by reading product labels carefully. You can choose natural alternatives, which are often free from anti-caking agents. Using fresh, unprocessed ingredients can also help eliminate exposure to this additive.
