Comparing:
E140: Chlorophyll & Chlorophyllins (Green Color)
E503: Ammonium Bicarbonate (Baker's Ammonia / Hartshorn)
E140 (Chlorophyll) is the natural magnesium-porphyrin green pigment extracted from grass, alfalfa, and nettles. INS 140(i), ADI is Not Limited (Quantum Satis), utilized to restore vibrant botanical green color to confectionery, oils, and pasta.
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.
