Potassium aluminium silicate

Potassium aluminium silicate is notable for nickel, histamine and salicylate. Clear on FODMAPs, lactose, gluten, fructose, oligosaccharides, sorbitol, sucrose, tyramine and oxalates.

Yes — Potassium aluminium silicate is high in nickel. Potassium aluminium silicate is mica, ground fine and used to give a pearl finish. It is a mined sheet mineral, and sheet minerals hold trace metals between their layers. Read against the regulation that governs it, this one is the exception among the silicates: nickel is a stated purity criterion for E 555 and for none of the others. A criterion is a CEILING and not a content, but the law does not set one where nothing is expected, so the ore-companion reasoning behind this level has the text on its side here.

Potassium aluminium silicate contains only low levels of histamine. Potassium aluminium silicate is mica, ground fine to give a pearl finish.

Potassium aluminium silicate contains only low levels of salicylate. Potassium aluminium silicate is a mineral used as a colour carrier and anti-caking agent. No relation to salicylate beyond membership of the additive group. Amounts vary by brand and recipe, so always check the label of the exact product.
