Lecithin

Lecithin (E322) is a generic term for a mixture of amphiphilic phospholipids and triglycerides. Over 95% of commercial food-grade lecithin is extracted mechanically and enzymatically from plant seeds, specifically soybeans, sunflower seeds, and rapeseed (canola). While lecithin was originally discovered in egg yolks (from the Greek lekithos), egg-derived lecithin is significantly more expensive and mandatory allergen labeling laws require it to be explicitly labeled as 'egg lecithin'.

Frequently Asked Questions

Is soy lecithin vegan?
Yes, 100% vegan. Soy lecithin is a byproduct of soybean oil refining and contains zero animal ingredients or derivatives.
How can I be sure lecithin is not from egg yolks?
Because eggs are a major top-8 food allergen, global food safety regulations (FDA, EFSA, FSSAI) mandate that egg-derived lecithin must explicitly declare eggs in the ingredients or allergen statement. Generic 'lecithin' or 'soy/sunflower lecithin' is plant-derived.
What is the difference between soy lecithin and sunflower lecithin?
Sunflower lecithin is extracted through cold-pressing without chemical solvents (like hexane) and is naturally allergen-free and non-GMO, making it the preferred choice for clean-label vegan foods.
