E282: Calcium Propionate (Bread Anti-Mold) vs. E631: Disodium Inosinate (IMP Meat Umami Synergist)
Comparing 2 standards across 9 specifications. 9 key differences identified.
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.
E631 (Disodium 5'-Inosinate / IMP) is the sodium salt of inosinic acid, a purine nucleotide naturally found in aged beef, katsuobushi bonito flakes, and cured meats. INS 631, ADI is Not Specified, multiplying glutamate umami flavor.
