Comparing:
E282: Calcium Propionate (Bread Anti-Mold)
E412: Guar Gum (Cold-Soluble Galactomannan)
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.
E412 (Guar Gum) is a natural galactomannan hydrocolloid extracted from guar beans (Cyamopsis tetragonoloba). INS 412, ADI is Not Limited (Quantum Satis), boasting 8x the thickening power of cornstarch and hydrating completely in cold water.
