Abstract
Abstract A dry hard canine biscuit having visually apparent, discrete particles, which contain (i) meat and/or meat by-product and/or (ii) farinaceous material and/or textured vegetable protein, distributed substantially uniformly throughout the biscuit is obtained by blending the non-fat solids portion of a canine biscuit dough with the particles which are substantially inert with respect to the dog biscuit dough, mixing the dry-blended mixture with water and with the fat portion of the pet biscuit dough to form a dough, forming the dough using low shear into pieces, and baking and drying the formed pieces to obtain a microbiologically stable product which can be packaged without a barrier material. The particle inertness is made possible by using particles having: (1) a moisture content of 35 percent by weight or less and (2) a water activity which is less than the water activity of said biscuit dough. There is a substantial absence of particle color bleed into the biscuit. An example of the textured vegetable protein is textured soy protein; and an example of the farinaceous material is wheat. The discrete, visually apparent dehydrated particles enhance the palatability and visual attractiveness of the dry biscuit.
