E322: Lecithin (Phospholipid Emulsifier & Viscosity Reducer) vs. E406: Agar-Agar (Seaweed Hydrocolloid Gel)
Comparing 2 standards across 14 specifications. 14 key differences identified.
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.
E406 (Agar-Agar) is a natural sulfated galactan polysaccharide hydrocolloid extracted from red algae seaweeds (Rhodophyta). INS 406, ADI is Not Limited (Quantum Satis), forming firm, brittle thermoreversible gels with huge hysteresis (melts at 85°C, sets at 35°C).
