Egg Yolk Lecithin
Egg Yolk Lecithin is a high-purity phospholipid fraction recovered from chicken egg yolk and refined to pharmaceutical specifications. It carries the European food additive number E322 and represents the original source from which lecithin was first isolated in the nineteenth century.
The material is a pale yellow waxy solid or fluid that holds a phosphatidylcholine content typically above 70 percent. Phosphatidylethanolamine, sphingomyelin, and minor lysophospholipids make up the balance, alongside trace cholesterol and triglycerides.
We source bulk Egg Yolk Lecithin from top China manufacturers for our partners, working with several of them. The manufacturers are in Hebei and Beijing. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Egg Yolk Lecithin is graded almost entirely by phosphatidylcholine purity.
Food grade material carries a phosphatidylcholine fraction of 40 to 70 percent and serves bakery, mayonnaise, and culinary cream applications. Pharmaceutical grades hit 70 to 80 percent phosphatidylcholine and supply intravenous lipid emulsions, liposomal drug carriers, and parenteral nutrition formulas.
Ultra-high purity fractions reaching above 95 percent phosphatidylcholine are produced by chromatographic refinement and used in research-scale liposome and exosome work.
Selected grades are also offered as deoiled powders for dry-blend pharmaceutical and nutraceutical use.
Applications
- Mayonnaise, hollandaise, and emulsified culinary sauces
- Premium bakery and patisserie creams
- Intravenous lipid emulsions for parenteral nutrition
- Liposomal carriers for drug delivery and cosmetic actives
- Inhalable and ophthalmic pharmaceutical formulations
- Infant nutrition products where source matching to human milk lipids is required
- Nutraceutical softgels delivering phosphatidylcholine for liver and cognitive support
- High-end ice cream and frozen dessert formulations
- Cosmetic serums and anti-ageing creams as a carrier matrix
- Research applications in biophysics and membrane studies
- Specialty chocolate where egg-derived emulsifiers are traditional
- Veterinary injectable nutrition products

How We Help Source Egg Yolk Lecithin
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Egg Yolk Lecithin out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Egg Yolk Lecithin together with other ingredients such as Polyglycerol Esters of Fatty Acids, Non-Dairy Creamer and Mono- and Diglycerides of Fatty Acids into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
The European Union approves Egg Yolk Lecithin as a food additive under E322, and in the United States it is Generally Recognized as Safe under 21 CFR 184.1400.
Allergen labelling for egg is mandatory in the European Union, the United States, Canada, Japan, and most other major jurisdictions.
The European Pharmacopoeia carries a monograph for egg phospholipid (Lecithinum ex ovo) covering pharmaceutical and parenteral grades. The United States Pharmacopeia includes corresponding monographs for lecithin and egg phospholipids used in injectable formulations.
Kosher certification is widely available. Halal certification depends on the egg sourcing chain and is available from selected suppliers.
Manufacturing Process
Egg Yolk Lecithin is produced from fresh or spray-dried chicken egg yolk.
The yolk is first separated from the egg white in a continuous breaking line and then either chilled for immediate processing or spray-dried for stable transport. Solvent extraction with ethanol or an ethanol-acetone mixture dissolves the phospholipid fraction while leaving most triglycerides and cholesterol in the residue.
The crude extract is concentrated under vacuum and further purified by selective precipitation with cold acetone. The phospholipid concentrate is then dried under nitrogen to limit oxidation.
Pharmaceutical and high purity grades undergo additional chromatographic polishing on alumina or silica columns to lift phosphatidylcholine content above 95 percent.
