Comparing:
E627: Disodium Guanylate (GMP Umami Synergist)
E965: Maltitol (Sugar Alcohol / 90% Sweetness)
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.
E965 (Maltitol) is a disaccharide polyol sugar alcohol produced by hydrogenation of maltose derived from cornstarch. INS 965(i), ADI is Not Specified (Excessive consumption may have laxative effect), delivering 90% the sweetness of sugar with 2.1 kcal/g.
