E556 – Aluminium Calcium Silicate
Anticaking agentDescription
A fine, white or nearly white, odorless powder; insoluble in water and organic solvents
Notes
Calcium aluminum silicate is a fine, white, odorless powder created by combining calcium, aluminum, and silica (the primary component of sand and glass). This compound is typically produced synthetically through controlled chemical processes, though similar compounds can be found naturally in certain minerals. As an anticaking agent, it prevents powdered foods from clumping together, ensuring they remain free-flowing and easy to use. You'll commonly find it in table salt, powdered spices, baking mixes, and other dry food products where preventing moisture absorption and clumping is crucial for product quality and consumer convenience. This synthetic additive is suitable for both vegetarian and vegan diets and doesn't conflict with religious dietary laws. While it contains aluminum, the amounts used in food are very small and are regulated by food safety authorities. Some health-conscious consumers prefer to minimize aluminum-containing additives in their diet, though current safety assessments indicate it's safe for consumption at approved levels.
