Comparing:
E140: Chlorophyll & Chlorophyllins (Green Color)
E500: Sodium Bicarbonate (Baking Soda / Ins 500ii)
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.
E500 (Sodium Carbonates / Sodium Bicarbonate NaHCO3) is a mineral salt leavening agent and pH buffer. INS 500(ii), ADI is Not Limited (Quantum Satis), decomposing under heat and acid to produce carbon dioxide bubbles that expand cakes, cookies, and pretzel crusts.
