E630 - Inosinsäure

Origin

Inosinic acid, also known as hypoxanthine riboside 5'-monophosphate, is a naturally occurring nucleotide. It can be produced commercially through microbial fermentation or extracted from meat or fish. It is a purine nucleotide monophosphate, meaning it is composed of a purine base (hypoxanthine), a sugar (ribose), and a phosphate group.

Usage

Inosinic acid is primarily used as a flavor enhancer in the food industry. It is often used in conjunction with glutamates, such as monosodium glutamate (MSG), to provide a synergistic umami taste. It enhances the savory flavor of foods. It is commonly found in processed foods, snack foods, sauces, and soups. The synergistic effect with glutamates means that lower concentrations of both inosinic acid and glutamates can be used to achieve the desired flavor enhancement, potentially reducing the overall sodium content in the final product. Typical usage levels are very low, usually in the parts per million range.

Side Effects

Inosinic acid is generally considered safe for consumption. It is a naturally occurring substance in the body and is metabolized as part of normal purine metabolism. However, individuals with gout or hyperuricemia (high levels of uric acid in the blood) may need to limit their intake of purine-rich foods and additives, including inosinic acid, as purines are metabolized into uric acid. There is no established ADI (Acceptable Daily Intake) for inosinic acid, indicating its low toxicity.

Regulatory Status

Inosinic acid (E630) is approved for use as a food additive in many countries, including the European Union and the United States. In the EU, it is listed as a permitted food additive with the E number E630. In the United States, it is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices.
