Disodium Inosnate

Disodium inosinate is a flavor enhancer that is often produced commercially through the fermentation of sugars by bacteria. It can also be derived from dried fish or seaweed. It is a salt form of inosinic acid.

Disodium inosinate is used to intensify savory (umami) flavors in foods. It works synergistically with other flavor enhancers like monosodium glutamate (MSG) and disodium guanylate. It is commonly found in instant noodles, soups, sauces, and snack foods.

Disodium inosinate is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when used as a food additive. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have also evaluated it. While generally considered safe, some individuals may be sensitive to high intakes of flavor enhancers, though scientific evidence for widespread adverse effects at typical consumption levels is mixed.
