Disodium 5-Ribonucleotides, E635, CAS no.4691-65-0, also called I + G, is a food additive manufactured through chemical synthesis of sodium salt of guanylic acid and inosinic acid, available as White to light yellow crystalline powder. Disodium 5â?²-Ribonucleotides is widely used as flavour enhancer as it can increase flavour significantly when using together with Monosodium Glutamate. Disodium 5â?²-Ribonucleotides (I+G) is a flavor enhancer a mixture of disodium Inosinate (IMP) and disodium guanylate (GMP) and is often used where a food already contains natural glutamates (as in meat extract) or added Monosodium Glutamate (MSG). It is primarily used in flavored noodles, snack foods, chips, crackers, sauces and fast foods.
