Why this verdict

E131 is patent blue V, a synthetic triarylmethane dye giving a blue colour to confectionery and beverages. SANHA and MUIS both classify E131 as halal, describing it as a synthetic dark bluish-violet colouring with no animal source. JAKIM Handbook 2010 lists it as Mushbooh only in liquid form, where the carrier solvent must also be halal — a product-level matter. As a synthetic dye, E131 is halal.

Food-safety note
Permitted as a food colour in Australia and New Zealand under the Food Standards Code (Schedule 15), subject to maximum permitted levels, and assessed safe by FSANZ before approval. A synthetic dye; rarely, sensitive people may have an allergic reaction. Reported as “banned” in some other countries — FSANZ notes this reflects different regulatory systems rather than a safety verdict. (Source: FSANZ; Food Standards Code Schedule 15.)
