E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer)
E501: Potassium Carbonate (Potash / Alkaline Noodle Salt)
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.
E501 (Potassium Carbonates / K2CO3) is an inorganic alkaline mineral salt. INS 501(i), ADI is Not Limited (Quantum Satis), used as the key 'Kansui' alkaline agent in Japanese ramen noodles and in the Dutch processing of cocoa powder.
