E170 is calcium carbonate, used as a white colour, anticaking agent, and acidity regulator in baked goods, confectionery, and supplements. SANHA classifies E170 as Halaal. JAKIM Handbook 2010 classifies E170 as Mushbooh, halal when obtained from rock mineral as a dry powder but doubtful in liquid form where the solvent must also be halal. MUIS marks E170 as syubhah, noting it may be extracted from a naturally occurring white mineral or from animal bones. Because that source is not disclosed on the label, E170 is doubtful by default.

Food-safety note

Permitted in Australia and New Zealand under the Food Standards Code (Schedule 15), at good manufacturing practice, as a colour, anti-caking agent, and acidity regulator. It is also a common dietary calcium source; JECFA set no numerical limit and it is regarded as safe. (Source: FSANZ; Food Standards Code Schedule 15.)
