Comparing:
E500: Sodium Bicarbonate (Baking Soda / Ins 500ii)
E951: Aspartame (Dipeptide Sweetener / 200x)
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.
E951 (Aspartame) is a methyl ester of the aspartic acid/phenylalanine dipeptide yielding ~200x the sweetness of sucrose. INS 951, ADI is 40 mg/kg bw/day, the historic sweetener in Diet Coke and tabletop sweetener packets.
