Comparing:
E407: Carrageenan (Dairy Stabilizer Hydrocolloid)
E627: Disodium Guanylate (GMP Umami Synergist)
E407 (Carrageenan) is a high-molecular-weight sulfated polygalactan extracted from red edible seaweeds (Chondrus crispus / Irish Moss). INS 407, ADI is 75 mg/kg bw/day, famed for stabilizing cocoa suspension in chocolate milk via kappa-casein binding.
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.
