5'-RIBONUCLEOTIDES

GENERAL

5'-Ribonucleotide products, Disodium Inosine-5'-monophosphate (IMP), Disodium-5'-guanosinemonophosphate (GMP) and their mixture (I+G), are white crystals or crystalline powder. They aresoluble in water and sparingly in alcohols but not in ethers. They are prepared by sugar fermentationfollowing purification process. They have very strong flavour enhancing activity. The greater benefitof them is the synergistic effect on improving the own natural tastes and flavours of almostprocessed foods when they are used in combination with MSG (Mono Sodium Glutamate). Thesynergistic 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'-Ribonucleotideproducts in food is approved by FDA.
