Disodium inosinate (also known as disodium 5′-ribonucleotides or E631) is a synthetic salt. Disodium inosinate(IMP) occurs naturally in certain foods, such as fish, meat, and other animal products; however, it can also be produced synthetically and added to foods in low levels to enhance the umami taste. Disodium inosinate has a good safety profile at current consumption levels; however, overconsumption of disodium inosinate may cause adverse effects.
What is disodium inosinate?
Disodium inosinate is a chemical compound that is used as a flavor enhancer. It is often added to foods, beverages, and medications as an umami flavor enhancer. Umami is one of the five basic tastes. Disodium inosinate is one of several related food additives known collectively as disodium guanylate (E621).
Disodium inosinate is a salt formed by the reaction of monosodium glutamate (MSG) with inorganic acid. The resulting product contains sodium (Na), disodium (2Na) or dipotassium (2K) and inorganic ions, such as chloride or sulfate.
Disodium 5 inosinate
Disodium 5 inosinate is an ingredient used to enhance the flavor of food. It can be found in many savory dishes and sauces. It is commonly added to foods as an enhancer for savory flavors. Disodium 5 inosinate is often used together with disodium guanylate or monosodium glutamate (MSG).
Disodium 5 Inosinate is a salt that occurs naturally in many foods and plants. It is also produced by fermentation of sugar or by chemical synthesis. The name comes from its chemical composition: disodium adenosine monophosphate and sodium salt (Na5IP).
How is disodium inosinate made?
Disodium inosinate is an umami flavor enhancer. It is a white crystalline powder that is soluble in water. This product is used to increase the savory taste of foods. Disodium inosinate can be used as a replacement for monosodium glutamate (MSG) when it is not desired to have a strong flavor in the product.
Disodium inosinate is made from inosine monophosphate (IMP), which comes from yeast extract. IMP is reacted with sodium bisulfite and disodium carbonate, which results in disodium inosinate.
The reaction equation is as follows: 
Also, disodium inosinate is made by reacting disodium guanylate with ammonia and ethanolamine under controlled conditions. The reaction produces the following chemical equation:
2NH3 + (CH2)4NH2·H2O + C6H10O5 = 2 (CH2)4NH2 + 3C6H10O5

Differences between disodium inosinate and guanylate
Disodium inosinate is an amino acid. Guanylate is a nucleotide.
Disodium inosinate and guanylate are flavor enhancers that are commonly added to food. They have the same function, but they are different compounds.
They both activate taste receptor cells to send signals to the brain that something is tasty and should be eaten. However, they do so by different mechanisms:
Guanylate produces an acidic solution when it comes into contact with water. This acidity activates taste receptors on the tongue that detect sourness; this is why you can taste guanylate without eating it directly (e.g., when you drink soda). When the acidity from guanylate activates these receptors, nerve impulses are sent to your brain telling you there’s something sour in your mouth — but it’s not actually sour at all! It just tastes like it would be sour if it were there because of its chemical structure.
Inosinate does not produce an acidic solution when it comes into contact with water; rather, it produces a basic solution that activates sweet receptors on your tongue — so not only do you “taste” sweetness from foods containing disodium inosinate.
Differences between disodium inosinate and disodium guanylate powder
Disodium inosinate and disodium guanylate are two of the most widely used flavor-enhancing food additives. They are used primarily to enhance the savory taste of umami, a fifth taste sense. The two chemicals both have a similar chemical structure, but they have different functional properties.
Disodium Inosinate vs Disodium Guanylate
Both disodium inosinate and disodium guanylate are derived from the amino acid, L-glutamic acid. They are used as flavor enhancers in a variety of foods including snack foods, meat products and dairy products.
Both disodium inosinate and disodium guanylate are used as flavor enhancers in a variety of foods including snack foods, meat products and dairy products. The difference is that disodium inosinate has an amine group attached to the carboxylate group on the side chain while disodium guanylate does not have an amine group attached to it.
Disodium inosinate vs MSG
The difference between disodium inosinate and monosodium glutamate (MSG) is that the former is a naturally occurring amino acid, whereas the latter is a processed food additive.
Disodium inosinate is a salt of inosine and sodium. Inosine is an organic compound that occurs naturally in the body. Disodium inosinate is used as a flavor enhancer in many foods. It has been shown to increase the amount of saliva produced when it is consumed by humans, which can lead to an increased perception of sweetness and saltiness.
Monosodium glutamate (MSG) is a flavor enhancer that is added to many different types of foods to enhance their taste. It was first discovered by Japanese scientists working at Ajinomoto Company in 1908, who found that it could be used as a flavor enhancer for foods. MSG has been used widely since its discovery and continues to be used today because it works effectively as an enhancer while having no negative side effects on humans. Some people experience headaches or other adverse reactions when they consume MSG, but these reactions are rare and most often occur after consuming large amounts of MSG over long periods of time (years).
What is disodium inosinate used for?
Disodium inosinate in food
Disodium inosinate is a flavor enhancer that is used as an additive to food. It is often found in foods that are made with monosodium glutamate (MSG). Disodium inosinate is also used to increase the flavor of meat and fish products. Disodium 5’-guanylate is a similar ingredient that can be used in place of disodium inosinate.
With MSG
Disodium inosinate is one of the many forms of monosodium glutamate, better known as MSG. MSG stimulates cells on your tongue causing you to experience flavour more intensely than usual. This helps you enjoy the taste of food even when it’s bland or low-fat.
With disodium 5’-guanylate
Disodium 5’-guanylate is another form of MSG that can be found in certain processed foods like canned soup or instant noodles. It occurs naturally in certain types of foods such as seaweed or mushrooms, but it is usually added to processed foods by manufacturers because it enhances their umami flavour.
Disodium 5’-guanylate may be safer than MSG since it does not produce the same reaction when consumed by some people who are sensitive to MSG. In fact, some studies suggest that disodium 5’-guanylate might help prevent some types of cancer when consumed regularly over time
Is disodium inosinate Safe?
In fact, its safety when used as a food additive has been approved by a variety of authorities, including the U.S. Food and Drug Administration (FDA), the European Food Safety Authority (EFSA), the Joint FAO/WHO Expert Committee on Food Additives (JECFA), as well as numerous other authorities.
FDA
In a FDA report, the compound is claimed to be safe for use in food as a flavoring adjuvant.
EFSA
