Why this verdict

E451 is triphosphates, mineral salts used as emulsifiers, stabilisers, and moisture binders in processed meat, seafood, and dairy. SANHA classifies E451 as Halaal. It is produced from inorganic phosphate rock, not from bone.

Food-safety note
Permitted as an emulsifier, stabiliser, and moisture binder in Australia and New Zealand under the Food Standards Code (Schedule 15). Triphosphates are widely used in processed meat and seafood; as with all phosphates, use is capped in many food categories because total dietary phosphate intake has been a focus of nutrition review.
