5'-RIBONUCLEOTIDES

GENERAL

5'-Ribonucleotide products, Disodium Inosine-5'-monophosphate (IMP), Disodium-5'-guanosine monophosphate (GMP) and their mixture (I+G), are white crystals or crystalline powder. They are soluble in water and sparingly in alcohols but not in ethers. They are prepared by sugar fermentation following purification process. They have very strong flavour enhancing activity. The greater benefit of them is the synergistic effect on improving the own natural tastes and flavours of almost processed foods when they are used in combination with MSG (Mono Sodium Glutamate). The synergistic effect can be recognized by cost savings. For example, 500gr of nucleotide (2%) + MSG (98%) have same flavor enhancing quality of 2,000gr MSG alone. The use of 5'-Ribonucleotide products in food is approved by FDA.
