E635 - Dinatrium-5'-ribonukleotid

Origin

Disodium 5'-ribonucleotides are a mixture of disodium inosinate (IMP) and disodium guanylate (GMP). These are nucleotides that occur naturally in animal and plant cells. Commercially, they are typically produced from yeast extract or by fermentation of sugars. They can also be produced from fish or meat, which is less common due to cost and ethical considerations.

Usage

Disodium 5'-ribonucleotides are used as a flavor enhancer, working synergistically with glutamates (like MSG) to provide an umami taste. They are often added to processed foods to enhance savory flavors and reduce the amount of sodium needed. Common applications include instant noodles, snack foods, sauces, canned vegetables, and processed meats. The effect is most pronounced when used in conjunction with monosodium glutamate (MSG); the combination can produce a flavor intensity several times greater than MSG alone. Typical usage levels are very low, usually in the range of 0.01% to 0.1% of the food product.

Side Effects

Disodium 5'-ribonucleotides are generally considered safe for consumption by most people. However, individuals with gout may need to limit their intake, as these compounds can increase uric acid levels in the body, potentially exacerbating the condition. Some individuals may also experience mild allergic reactions. Regulatory bodies like the EFSA and FDA have evaluated the safety of disodium 5'-ribonucleotides and have established acceptable daily intakes (ADI) or have deemed them generally recognized as safe (GRAS) when used at levels consistent with good manufacturing practices. There is no specific ADI established, but usage is limited by good manufacturing practice.
