Comparing:
E170: Calcium Carbonate (Mineral White Color / Anti-Caking)
E627: Disodium Guanylate (GMP 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.
E627 (Disodium 5'-Guanylate / GMP) is the sodium salt of guanylic acid, a purine nucleotide naturally concentrated in dried shiitake mushrooms. INS 627, ADI is Not Specified, exhibiting massive 8x–30x synergistic umami amplification when paired with MSG.
