Abstract
Abstract A dry hard canine biscuit having visually apparent, discrete meat and/or meat by-product particles 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 into pieces, and baking and drying the formed pieces to obtain a microbiologically stable product which can be packaged without a barrier material. Meat and/or meat by-product particle inertness is made possible by using particles having: (1) a moisture content of 35% by weight or less and, (2) a water activity which is less than the water activity of said biscuit dough. The substantial absence of meat particle color bleed into the biscuit is principally due to the use of meat products wherein the color is formed as part of the protein matrix. The discrete, visually apparent dehydrated meat particles enhance the palatability and visual attractiveness of the dry biscuit.

Claim 1
Independent Claim
343 words
In a method for making a dry hard canine biscuit from a final biscuit dough containing a non-fat solids portion which contains farinaceous material, an added fat portion and an added water portion, the improvement consisting essentially of the steps of: (a) admixing dehydrated meat and/or meat by-product particles or meat and/or meat by-product particles having a moisture content of less than or equal to about 35 percent by weight of the particles with said non-fat solids portion of a final biscuit mixture to form a substantially homogeneous dry blended mixture, no fat being added in step (a) except the indigenous fat which is present in said meat and/or meat by-product particles, and said meat and/or meat by-product particles being present in an amount of about 3 to about 15 weight percent, based on the total weight of said dry hard canine biscuit; (b) admixing dry blended mixture (a) with said added-water portion of said final biscuit dough to form a first stage dough, said added-water portion being present in an amount of about 20 to 30 weight percent, based on the total weight of said final biscuit dough; (c) mixing said added-fat portion of the biscuit dough with said first stage dough to form said final biscuit dough, 5 weight percent, based on the total weight of said final biscuit dough; (d) forming said final biscuit dough into pieces under low-shear non-cooking forming conditions which maintain the discreteness of said particles, using a forming pressure less than 75 p.s.i.g., and a forming temperature of up to 110 degrees Fahrenheit and (e) baking and drying said pieces to form said dry hard biscuit, which is shelf stable, wherein the water activity of said meat particles in step (a) is about 0.7 or lower and is less than the water activity of the final dough, obtained by admixing said non-fat solids portion, said fat portion and said water without said particles, which is at least 0.90 and whereby a dry hard biscuit is produced having discrete visually apparent meat particles distributed substantially uniformly throughout.
