It's easy to purchase MSG as a consumer in reasonably low quantities, which is convenient for me, an umami fiend. Glutamates react synergistically with nucleotides to amplify the umami sensation. And the "artificial" version of these nucleotides is commonly sold as Disodium Ribonucleotides.
My question: does anyone know if it's possible to purchase these in reasonably low quantities? My research has indicated that it is only possible to purchase in industrial quantities from large suppliers, but I don't particularly want 500kg of Disodium Ribonucleotides in my house. Has anyone discovered anything more suited to consumers?
