Low concernWhat is Calcium ribonucleotide?
E634 is a food additive used as a flavor enhancer. It is a mixture of calcium salts of guanylic acid and inosinic acid. For industrial use, it is obtained through the bacterial fermentation of sugars or from meat or sardines, which means it can have either plant or animal origin. Inosinate and guanylate do not impart the 'umami' taste characteristic of monosodium glutamate, but they enhance many natural flavors, allowing for a reduction in the amount of salt needed. It is used in the quantities specified in recipes in all types of food products, including alcoholic and non-alcoholic beverages.
