Lecithin (E322): what it is and where it’s used

Lecithin (E322) is the emulsifier in most chocolate. It can be made from soy, sunflower, rapeseed or egg yolk. When it comes from soy or egg, the label must say so in the EU, the UK, the US and the Gulf. When a pack says only “lecithin”, Bravoora shows the source as unclear instead of guessing.

What is lecithin?

Lecithin (E322) keeps fat and water mixed. It can be made from soy, sunflower, rapeseed or egg yolk. Soy and egg are declared allergens in the UK, the EU, the US, Canada and the Gulf, so when lecithin comes from one of those the label must name it. When a pack says only “lecithin” or “emulsifier (E322)”, the source is not stated on the pack, so it is something to check rather than something to rule out.

Where is lecithin found?

  • Chocolate and chocolate coatings usually contain it.
  • Bread, cakes and biscuits use it to keep the crumb soft.
  • Margarine, spreads and dressings use it to keep oil and water mixed.
  • Infant formula and supplements can contain it.
