E471: Mono- & Diglycerides of Fatty Acids (Bread Softener)
E503: Ammonium Bicarbonate (Baker's Ammonia / Hartshorn)
E471 is an authorized food emulsifier composed of glycerol esterified with one or two fatty acid chains (glycerol monostearate / monooleate). INS 471, ADI is Not Limited (Quantum Satis), globally recognized as the ultimate crumb softener and amylose complexing agent in bakery.
E503 (Ammonium Bicarbonate / (NH4)HCO3) is a historic chemical leavening salt. INS 503(ii), ADI is Not Limited (Quantum Satis), decomposing 100% into gaseous CO2, ammonia, and water at temperatures >60°C to create ultra-crisp, airy crackers and cookies.
