Comparing:
E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer)
E306 is a natural mixture of alpha-, beta-, gamma-, and delta-tocopherols steam-distilled from vegetable oils (soybean, sunflower). INS 306, ADI is Not Limited, serving as the gold standard lipid-soluble antioxidant in fats and oils.
Lecithin (E322) is a complex mixture of zwitterionic polar phospholipids (phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol) derived from soybeans, sunflower seeds, or egg yolks, functioning as an amphiphilic oil-in-water surfactant and chocolate viscosity reducer.
