E270: Lactic Acid (Biological Acidulant) vs. E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer)
Comparing 2 standards across 14 specifications. 14 key differences identified.
E270 (L-Lactic Acid) is a natural alpha-hydroxy acid produced by fermentation of carbohydrates by lactic acid bacteria (Lactobacillus). INS 270, ADI is Not Limited (Quantum Satis), imparting a smooth, mild sour taste in dairy, beers, and bakery sourdoughs.
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.
