What Is Disodium Inosinate?

A flavor enhancer that works synergistically with MSG (monosodium glutamate) to intensify umami taste. Derived from animal sources (typically sardines or pork) or produced by bacterial fermentation. Almost always used in combination with disodium guanylate as 'I+G' flavor enhancers.

Mechanism of Action

Inosinate activates umami taste receptors synergistically with glutamate, meaning the combination produces a much stronger umami sensation than either alone. This synergy allows food manufacturers to use less MSG while achieving the same flavor intensity. Metabolized as a normal purine nucleotide.
