Abstract
A hardness modifiable edible dog chew produced by extruding a vegetable starch mixture into beads and then injection molding the beads into the shape of the dog chew. The mixture includes lecithin, calcium carbonate and optionally a dog attractant. The hardness of the dog chew can be varied by subjecting it to expansion by microwaving
Claims13
A method of producing a hardness-modifiable edible dog chew, comprising the steps in sequence of:
- mixing vegetable starch, about 2% lecithin, and about 4-6% calcium carbonate, wherein said mixture comprises about 90-94% by weight vegetable starch;
- adjusting the moisture content of said mixture to about 12% by weight;
- extruding said mixture into beads of about 3-10 millimeters;
- injection molding the beads into the shape of a dog chew, such injection molding causing most of the beads to melt and sterilizing the ingredients of the beads;
- cooling the resulting dog chew;
- and
- ejecting the dog chew wherein said water content, subsequent to injection molding is adjusted below 12% by weight.

A method of producing a hardness-variable edible dog chew, having a desired percentage of starch and protein components, comprising the steps in sequence of:
- extruding a mixture of vegetable starch and vegetable protein, about 2% lecithin, about 4-6% calcium carbonate and water into beads of about 3-10 millimeters, wherein said vegetable starch is present in an amount of at least 90 percent by weight and wherein said water content of said beads is about 12% by weight;
- injection molding the beads in an injection molding machine so as to melt and sterilize the ingredients of the beads;
- cooling the molded dog chew while in the injection molding machine until the molded dog chew solidifies;
- and
- ejecting the dog chew from the injection molding machine and said water content subsequent to injection molding is below 12% by weight.
