Comparing:
E282: Calcium Propionate (Bread Anti-Mold)
E290: Carbon Dioxide (Carbonation & MAP Gas)
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.
E290 (Carbon Dioxide / CO2) is an authorized food additive functioning as a carbonating gas, modified atmosphere packaging (MAP) preservative, and cryogenic freezing propellant. INS 290, ADI is Not Limited (Quantum Satis).
