Coated particulate material used to enable the incorporation of calcium materials in a beverage product (especially those having a low pH) preserved with sodium hexametaphosphate (SHMP) are disclosed. The particulates are made up of a substrate material, such as a calcium salt, such as calcium phosphate. The substrate material can, in preferred embodiments, be incorporated into a prill which utilizes a sterol as the prilling material. The substrate material, preferably in the form of a prill, is then coated with a phospholipid coating, such as hydrogenated phosphatidyl choline, such that the final coated particulate product includes from about 70% to about 200% (by weight of the substrate) of the phospholipid coating. Beverage compositions which include these coated particulates are also disclosed.
