E160a: Beta-Carotene (Provitamin A Orange Color) vs. E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer)
Comparing 2 standards across 14 specifications. 14 key differences identified.
E160a (Beta-Carotene) is a fat-soluble orange carotenoid tetraterpenoid obtained by synthesis, fermentation of Blakeslea trispora, or plant extraction. INS 160a(i)/(ii), ADI is Not Specified, providing deep orange-yellow hues in dairy, juices, and fats.
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.
