【Product Overview】
Disodium 5’-Ribonucleotide, commonly known as I+G, is a nucleotide-based food flavor enhancer. It is a mixture of Disodium 5‘-Inosinate (IMP) and Disodium 5’-Guanylate (GMP) in a 1:1 ratio
Our food grade I+G is a white to off-white crystalline powder, odorless, with a distinct umami taste. The product is produced through advanced fermentation or enzymatic hydrolysis processes using starch or sugar as raw materials, in full compliance with GB 1886.171-2016 national standard. It is highly soluble in water and exhibits excellent synergistic umami-enhancing effects when used in combination with monosodium glutamate (MSG)
