Description
The food additive E631, known as disodium inosinate, is a flavor enhancer belonging to the group of ribonucleotides. It occurs naturally in animal and plant tissues, such as meat, fish, and mushrooms. Industrially, it is obtained by bacterial fermentation of sugars or by extraction from fish broth.
Chemically, it is the disodium salt of inosinic acid, a nucleotide that stimulates umami taste receptors on the tongue. Its main function is to enhance the flavor of foods, often in combination with monosodium glutamate (E621), with which it produces a synergistic effect.
The history of E631 dates back to the early 20th century, when umami was identified as the fifth basic taste. In the European Union, it was authorized as a food additive after evaluations by the European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA). EFSA has established an Acceptable Daily Intake (ADI) of 120 mg/kg body weight per day for the sum of E631 and E627 (disodium guanylate). This ADI is considered safe for the general population, including children and adults. The World Health Organization (WHO) also supports this assessment.
Regarding labeling, E631 must appear in the ingredient list of products containing it, either by its name or its E number. Although it is a safe additive for most people, some may experience adverse reactions at very high doses.
Overall, the food safety of E631 is well documented, and its use is regulated to ensure it poses no health risk.
E631 is mainly used in processed foods to enhance umami flavor, especially in products where a savory and tasty flavor is desired. Food categories that include it are: savory snacks (potato chips, nachos), instant soups and broths, sauces (ketchup, soy sauce, barbecue sauce), prepared dishes (instant noodles, rice dishes), processed meat products (sausages, hot dogs), and seasonings.
In the Spanish market, it is commonly found in brands such as Knorr, Gallina Blanca, Lays, and in supermarket products from Mercadona or Carrefour. EU Regulation 1333/2008 sets maximum usage limits for E631, which vary by food category. For example, in cereal and potato-based snacks, the limit is 500 mg/kg; in soups and broths, 500 mg/kg; in sauces, 500 mg/kg; and in meat products, 500 mg/kg. In the United States, the FDA classifies it as Generally Recognized as Safe (GRAS) and does not set a specific maximum limit, but its use must comply with Good Manufacturing Practices. In Japan, E631 is also approved and widely used in traditional cooking to enhance umami.
E631 is considered safe by major food safety agencies, such as EFSA and WHO, at authorized doses. Toxicological studies have not shown significant adverse effects in humans at normal intake levels. However, at very high doses (exceeding the ADI), isolated cases of reactions such as headache, nausea, or palpitations have been reported, although there is no conclusive evidence that E631 is the direct cause.
The biological mechanism of E631 involves activation of T1R1/T1R3 taste receptors on the tongue, which are specific for umami. No genotoxic, carcinogenic, or teratogenic effects have been identified in animal studies. Sensitive populations include people with fish allergy, as E631 may be derived from marine sources, although most commercial products are obtained by fermentation. Caution is also recommended for people with gout, as inosinate is metabolized to uric acid, but the amounts present in foods are minimal and do not pose a significant risk. No interactions with medications are known.
In conclusion, EFSA and WHO consider that E631 does not pose a health risk under authorized conditions of use.
