Comparing:
E282: Calcium Propionate (Bread Anti-Mold)
E951: Aspartame (Dipeptide Sweetener / 200x)
E282 (Calcium Propionate) is the calcium salt of propionic acid, the premier mold and 'rope' bacteria inhibitor in industrial yeast-leavened bakery goods. INS 282, ADI is Not Limited (Quantum Satis), preserving sliced bread for weeks without retarding yeast activity.
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.
