Calcium inosinate

Calcium inosinate is a flavour enhancer. It is typically produced by fermenting sugars to create inosinic acid, which is then reacted with calcium salts. It is often used in combination with other flavour enhancers like disodium guanylate.

Calcium inosinate is used to intensify the savoury, umami taste of foods. It is most commonly found in processed foods such as instant noodles, soups, and snacks where it contributes to a moreish flavour profile. It works synergistically with other flavour enhancers to provide a richer taste experience.

Calcium inosinate is authorised as a food additive in Great Britain and is listed on the Register of Food Additive Authorisations. It has been evaluated by EFSA, which has established an acceptable daily intake (ADI) for inosinic acid and its salts. At typical consumption levels found in food, it is not considered to pose a health risk. Some studies suggest that high intakes of purines, which are found in inosinates, may be a concern for individuals with gout, but evidence at typical dietary intakes is mixed.
