Why this verdict

E450 is diphosphates, mineral salts used as raising agents, emulsifiers, and stabilisers in baked goods, processed cheese, and meat products. SANHA and MUIS both classify E450 as halal. MUIS notes they are sodium and potassium salts of phosphoric acid (E338). They are synthetic mineral salts, distinct from edible bone phosphate (E542), so E450 is halal.

Food-safety note
Permitted as a raising agent, emulsifier, and stabiliser in Australia and New Zealand under the Food Standards Code (Schedule 15). Diphosphates are widely used in baked goods and processed cheese; as with all phosphates, use is capped in many food categories because total dietary phosphate intake has been a focus of nutrition review. (Source: FSANZ; Food Standards Code Schedule 15.)
