Abstract: The invention provides a film comprising a phosphoprotein preparation, wherein the phosphoprotein preparation has been obtained by partially cross linking a partial hydrolysate of casein or a caseinate, a source of one or more physiologically acceptable cations, and a plasticizer. The film is preferably edible and substantially soluble. In particularly preferred embodiments, the source of one or more physiologically acceptable cations comprises natural milk calcium phosphate, and the plasticizer is glycerol.

Abstract: The invention provides, in one aspect, compositions for delivering a bioactive metal ion to a mammal, the compositions comprising (a) an effective amount of a source of the bioactive metal ion, (b) a phosphoprotein preparation obtained by partially cross linking a partial hydrolysate of casein or a caseinate, and (c) one or more physiologically acceptable diluents or carriers. Also provided are compositions for remineralising tooth enamel and/or for treating or preventing dental caries, tooth erosion, dentinal hypersensitivity or gingivitis in a mammal, wherein the compositions comprise an effective amount of such a phosphoprotein preparation, in combination with one or more carriers or diluents. In related aspects, the invention provides methods of using such compositions. Also provided are novel phosphoprotein preparations suitable for use in such compositions and methods.

Abstract: An edible dough is described for use in an oral delivery method for administering a medicament to an animal. The dough is comprised of flour, soluble fibre, either oil or water and an optional range of additional ingredients thus forming a dough that can be moulded around a medicament. A key improvement of the present invention dough is that it has extensibility characteristics that allow it to form a homogeneous mass with the medicament. As a result of the improved extensibility, it is very difficult for an animal to separate out the medicament from the dough thus allowing easy administration of medicaments such as pills and tablets to an animal.
