Abstract

A process for making a heat expandable dog chew comprised primarily of injection molding potato starch granules and an attractant is disclosed.

Claims

1. A method of producing a hardness-adjustable edible dog chew, comprising the steps of:

extruding a mixture of a potato starch, water and calcium carbonate to form granules; and

injection molding such mixture into the shape of the dog chew.

2. The method of claim 1 wherein the starch and water weight content of the granules is about 70% starch and the weight content of the water is about 15%, and the weight content of the water is reduced to about 10% during the injection molding step.

3. The method of claim 1 further comprising the steps of adding to the mixture about 1-5% by weight natural vegetable additives and about 1-5% by weight of an attractant.

4. The method of claim 1, wherein the granules are injection molded at a pressure of about 1,000-2,500 PSI and at a temperature of about 250°
