The present invention provides a composition of stable amorphous calcium carbonate (ACC) and a food product containing the composition.

An enclosed amorphous calcium carbonate (ACC) composition contains a number of solid enclosed amorphous calcium carbonate particles, each of which contains: i. The amorphous calcium carbonate core contains amorphous calcium carbonate and at least one agent to stabilize the amorphous calcium carbonate in an amorphous form; And ii. An enveloping matrix containing at least one coating layer, wherein at least one coating layer contains an enveloping agent consisting of a group consisting of a free film-forming polymer and a lipid, and wherein at least one coating layer is at least partially coated with the amorphous calcium carbonate nucleus, The film-forming polymer is selected from cellulose, cellulose derivatives, methyl methacrylate, and any combination thereof, wherein the encapsulated matrix maintains an amorphous form of calcium carbonate when exposed to a moisture or aqueous medium.
