Comparing:
E170: Calcium Carbonate (Mineral White Color / Anti-Caking)
E631: Disodium Inosinate (IMP Meat Umami Synergist)
E170 (Calcium Carbonate / CaCO3) is a fine mineral salt mined from limestone or precipitated synthetically. INS 170(i), ADI is Not Limited (Quantum Satis), serving as a white surface colorant, acidity buffer, anti-caking agent, and calcium nutrient fortificant.
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.
