Comparing:
E414: Gum Arabic (Acacia Gum Emulsifier)
E627: Disodium Guanylate (GMP Umami Synergist)
E414 (Gum Arabic / Acacia Gum) is a complex arabinogalactan-protein glycoprotein exudate harvested from Acacia senegal trees. INS 414, ADI is Not Limited (Quantum Satis), the premier film-forming emulsifier for citrus beverage flavor oils.
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.
