  • Patent number: 6905719
    Abstract: A savory, smooth-textured, bakeable and shelf-stable product is prepared as a three-phase formulation, including an aqueous liquid phase, a dispersed fat phase and a solids phase, preferably containing a savory ingredient, preferably a cheese flavoring component, in significant proportion. The liquid phase is present in sufficient quantity to suspend and disperse the fat and solids phases and to have sufficient dissolved solids and humectants to raise the viscosity for this phase sufficiently to result in a creamy texture for the final product. The savory flavor ingredients are present as undissolved solids of sufficiently small particle size to provide the proper flavor release for the flavor and a texture consistent with the savory flavor. Preferred cheese products will have a lubricous, slippery, smooth mouthfeel and a flavor release that endures until the palate is essentially clean. The product can be applied to unbaked doughs prior to baking and retain their desired properties after baking.

The liquid phase is present in sufficient quantity to suspend and disperse the fat and solids phases. The dispersed fat must have sufficiently small droplet size raise the viscosity for this phase sufficiently to result in a creamy texture for the final product.

  • Patent number: 6863911
    Abstract: A creamy product with a lubricious mouthfeel is bake-stable and suitable as a filler or topping for baked goods. In a preferred form, it comprises: at least 30% by weight of a discontinuous fat portion; at least 20% of a continuous aqueous liquid component for providing sweetness and stability, comprising liquid sugar and liquid polyol, wherein the combined weight of liquid sugars and liquid polyols amounts to from 40 to 95% solids by weight of the aqueous liquid component, and the continuous aqueous liquid component preferably contains less than 20% water. An optional suspended solids portion can be employed. The creamy product, wherein the moisture content is from 2 to 10% by weight of the total composition, and the combined amount of the sugar, polyol and other soluble solids comprises from about 25 to 65% of the total product and is sufficient to provide an Aw of less than 0.5 for the total product, can be combined with a bakeable dough and baked.
