Is E340 halal?
E340 is generally considered halal. E340 — Potassium phosphates (i) Monopotassium phosphate (ii) Dipotassium phosphate (iii) Tripotassium phosphate — is used in food as emulsifier, humectant, sequestrant, stabiliser, thickener. The assessment is straightforward here: E340 is produced from plant or mineral raw materials, a category Islamic dietary law accepts in food. That holds regardless of brand, so a product is not made doubtful by containing E340 alone.

Sourcing and scholarly views on E340
There is no significant scholarly disagreement over additives like E340. Substances of plant, mineral or synthetic origin are permissible across the schools of Islamic law, under the principle that foods are permitted unless specifically prohibited — the position the European Council for Fatwa and Research applies to plant-derived and synthetic E-numbers. The practical question scholars do raise is cross-contamination during manufacturing, which is a matter for product certification rather than for the additive itself.

What this is based on
The classification of E340 rests on public records rather than opinion: the Open Food Facts taxonomy supplies the origin signal and the technological function, the UK Food Standards Agency register confirms authorisation status, and Commission Regulation (EU) No 231/2012 defines which raw materials it may legally be made from.
