What E322 actually is
Lecithin is an emulsifier and the reason chocolate flows smoothly through a moulding machine instead of seizing up. It reduces the friction between cocoa particles and fat, which lets manufacturers use less cocoa butter. It also stops margarine spitting in a pan and keeps powdered drinks dissolving instead of clumping.
What it is made from
Soya beans are the dominant source, extracted as a by-product of soybean oil refining. Sunflower lecithin has grown rapidly because it avoids the soya allergen declaration and appeals to non-GMO positioning. Rapeseed lecithin is also used. Egg yolk lecithin exists and appears mainly in specialist products and pharmaceuticals.
Vegan, vegetarian, and halal status
In practice, lecithin in packaged food is plant-derived and suitable for vegan and halal diets. The label helps here more than with most additives, because soya and egg are both declared allergens, so a pack must say soya lecithin or egg lecithin rather than leaving it vague. If it simply says lecithin with no allergen declaration, it is not soya or egg, which in practice means sunflower or rapeseed.
Is E322 safe?
Lecithin is a normal component of food and of cell membranes throughout the body. Egg yolk is roughly a tenth lecithin by weight. EFSA did not set a numerical intake limit when it re-evaluated the additive, and it is permitted in infant formula, which is the strictest category any additive faces.
- No established concerns at dietary levels
- Soya lecithin contains only trace soya protein, so most people with soya allergy tolerate it, but it is still declared
- Permitted in infant formula, which reflects a high confidence threshold

- FDA (US)
- Generally recognized as safe.

Common questions
- Is soya lecithin vegan?
- Yes. It is extracted from soya beans during oil refining and contains nothing animal-derived.
- Is lecithin halal?
- Plant lecithin from soya, sunflower, or rapeseed is acceptable. Egg lecithin is also acceptable to most. The practical answer is yes for packaged food.
- Can I eat soya lecithin with a soya allergy?
- Most people with soya allergy tolerate it because it contains only traces of soya protein, but it is still a declared allergen and the decision belongs with your clinician, not a label.
- Why is lecithin in chocolate?
- It makes molten chocolate flow more easily, which lets makers use less cocoa butter and still get a smooth product. Under about half a percent does the job.
- Is sunflower lecithin better than soya lecithin?
- They perform the same job. Sunflower avoids the soya allergen declaration and sidesteps GMO concerns, which is why it has grown, but there is no established nutritional difference.
Checking a real pack
This page answers the code. The pack in your hand is what decides, because the same code can come from different sources depending on the manufacturer. LabelWise, formerly SafeChoice, scans the label and explains what is in front of you.
LabelWise content is educational and describes how additives are made, regulated, and labelled. It is not medical, dietary, or religious advice. For certification questions, the mark on the pack and the certifying body are the authority.
