Product Introduction & Core Advantages
Disodium 5'-Ribonucleotide (I+G) is a compound umami food additive made from microbial fermentation. It consists of 50% disodium inosinate (IMP) and 50% disodium guanylate (GMP). When compounded with monosodium glutamate, it produces an extremely strong synergistic effect, which can increase the umami intensity by several times. It effectively masks fishy odor, bitter taste and other unpleasant off-flavors, enhances rich meaty flavor, and helps manufacturers reduce salt usage to develop low-salt food formulas.

This crystalline powder dissolves quickly in water without sediment. It maintains good stability under neutral pH and conventional high-temperature sterilization and cooking conditions, and will not decompose easily during food production.
