What it is and where it comes from
Lecithin is a natural fat-like substance that helps oil and water mix. Food lecithin is pressed out of soybeans, sunflower seeds or rapeseed, or more rarely taken from egg yolk. No pig or slaughtered animal is involved.
Where you find it
Chocolate, margarine, spreads, biscuits, bread, instant powders, baby formula and cooking sprays.
What to look for on the label
Usually written as "soy lecithin", "sunflower lecithin" or "emulsifier (E322)". Nothing to check for halal.
This is a guide, not a fatwa. Recipes change, so check the label, look for halal certification, and ask your local imam where scholars differ.
