Calcium inosinate

Calcium inosinate (CAS 38966-29-9), also known as E633, is the calcium salt form of inosine-5'-monophosphate used as a flavor enhancer in food manufacturing. It functions synergistically with glutamates to amplify savory, umami taste profiles at low use levels, reducing the need for sodium-based flavor compounds.

In processed foods, E633 is used in soups, sauces, seasonings, and snack coatings where consistent umami depth is required across large-scale production runs. Meat and poultry processors incorporate it into marinades and cured product formulations to enhance perceived savoriness without increasing sodium content.

In low-sodium or reduced-MSG product lines, it allows formulators to maintain flavor intensity while meeting clean-label or dietary targets. Pharmaceutical applications include its use as a functional excipient or active component in nutritional preparations targeting nucleotide supplementation.

Calcium inosinate is supplied as a white to off-white crystalline powder. Food-grade material is the standard commercial form, with specifications aligned to FCC requirements. Pharmaceutical-grade material is available for buyers requiring tighter specification compliance in nutraceutical or healthcare product manufacturing.
