A dry suspendible enteric coating composition for suspension in water and then encasing orally ingestible articles. The dry suspendible enteric coating composition comprises a pH-dependent polymer selected from a group containing alginates and alginic acids, a pH-independent water insoluble polymer selected from the group comprising ethylcellulose and ethylcellulose-containing compositions, and a plasticizer selected from the group containing triethyl citrate, glycerin, propylene glycol, triacetin, acetylated monoglycerides, dibutyl sebacate, polyethylene glycols, sorbitals, middle chain triglycerides and combinations thereof. A three-step method for providing a stable outer enteric coating on an ingestible item comprising a first step of encasing the item with a suspension comprising a mixture of at least a sugar and a microcrystalline cellulose, a second step of then encasing the item with a suspension comprising a mixture of a film-forming polymer and a plasticizer, and a third step of finally encasing the item with the enteric coating composition.
