E163: Anthocyanins (Grape Skin & Berry Red/Purple) vs. E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer)
Comparing 2 standards across 14 specifications. 14 key differences identified.
E163 (Anthocyanins) are natural water-soluble flavonoid polyphenol pigments extracted from grape skins, elderberries, and black carrots. INS 163, ADI is 2.5 mg/kg bw/day (grape skin extract), exhibiting pH-dependent colors from red to blue.
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.
