Alternate Names

Soy Lecithin, Hydroxylated Lecithin


Composed of phosphoric acid, choline, fatty acids and glycerol, it is a natural antioxidant and emulsifier. Egg yolks contain a high percentage of lecithin. Extracted from eggs, soybeans, sunflower oil, or corn. Used as an antioxidant and as an emulsifier (to help keep oils and water from separating). Hydroxlydated lecithin is used as an anti-foaming agent. Soy lecithin is obtained by degumming crude soy oil. Steam or Warm water is added to the crude soy oil, the mixture is stirred for 10-60 minutes and then the oil insoluble sludge is separated from the oil by centrifuge. The sludge is then bleached once or twice to reduce the color. Additives (soy oil, fatty acids or calcium chloride) can also be added to keep the final product from becoming a plastic solid when it is cool.

Researcher Comments

Commercially processed soy lecithin is derived from soybean oil. Since most people with soy allergies are allergic to the soy protein (not the oil), some can tolerate soy lecithin. However, contamination does occur (meaning that protein can be found in soybean oil). Those with severe soy allergies should avoid altogether. Note that since most soy lecithin is derived from genetically modified soybeans, we recommend that people avoid soy lecithin unless it is from an organic and non-genetically modified source.
