Comparing:
E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer)
E635: Disodium 5'-Ribonucleotides (I+G Blend)
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.
E635 (I+G) is a standardized 50/50 co-crystallized blend of disodium inosinate (E631) and disodium guanylate (E627). INS 635, ADI is Not Specified, serving as the commercial standard umami booster in global food manufacturing.
