Why this verdict
E921 is L-cystine, an amino acid used as a flour-treatment agent in bread and bakery products and in hair supplements. SANHA classifies E921 as Mushbooh and notes the source can be horse hair or synthetic. No other major halal authority in the source corpus has published a per-additive position on E921. Without source disclosure the additive defaults to doubtful unless the product carries halal certification confirming a synthetic source.

Permitted as a flour-treatment agent in Australia and New Zealand under the Food Standards Code (Schedule 15). An amino acid (cystine) used to condition dough; regarded as safe at the levels used in food. (Source: FSANZ; Food Standards Code Schedule 15.)
