Soy Lecithin (Phospholipids) substances

Soy lecithin or Phospholipids contain various substances such as Phospholipids, triacylglycerols, fatty acids, and glycolipids. The significant phospholipids include phosphatidylcholine, phosphatidylethanolamine, and inositol-containing phosphatides.

There are two forms of soy Lecithin: Soy Lecithin Oil and Deoiled soy Lecithin.

  1. Crude Soy Lecithin Oil Fractionation:
    Soybean Oil: 35%-55%
    Phosphatidylcholine (PC): 15-18%
    Phosphatidylethanolamine (PE): 12-14%
    Inositol phosphatides (PI): 9-10%
    Phosphatidic acid (PA): 3-5%
    Minor PLs: 2%
    Glycolipids: 8-10%
    Complexed sugars: 3-5%
  2. Deoiled Soy Lecithin (Powder/granules)
    Phosphatidylcholine (PC): 20-23%
    Phosphatidylethanolamine (PE): 20%
    Inositol phosphatides (PI): 9-10%
    Phosphatidic acid (PA): 8%
    Minor PLs: 5-8%
    Glycolipids: 8-10%
    Complexed sugars: 8%
    Neutral lipids: 3%
