Abstract

A method for manufacturing an edible dog chew includes the steps of: extruding a first edible mixture through a mold having an opening in a first direction to form a lengthened chew interior material; cutting the lengthened chew interior material into defined lengths to form at least one cut chew interior material; drying the cut chew interior material to form a chew interior; and coating the chew interior with a second edible mixture different from the first edible mixture. Further methods and pet chews are also provided.

Claims

1. A method for manufacturing an edible dog chew comprising the steps of:

cooking a first edible mixture at a temperature between 100 and 110 degrees Celsius;

extruding the first edible mixture through a mold having an opening in a first direction to form a lengthened chew interior material;

cutting the lengthened chew interior material into defined lengths to form at least one cut chew interior material;

following the cutting, drying the cut chew interior material to form a chew interior;

following the drying, coating the chew interior with a second edible mixture different from the first edible mixture; and

wherein the first edible mixture is a starch-based mixture and has at least over 50 percent by weight of starch material, and the first edible mixture also includes an animal-based material, wherein the animal-based material is fresh beef, pork, chicken, duck or fish in a weight percentage of 10 to 15 percent of the first edible mixture.

2. The method as recited in claim 1 wherein a length of the lengthened chew interior material is at least 0.5 meters.

3. The method as recited in claim 1 wherein the defined lengths are between 5 and 20 centimeters.

4. The method as recited in claim 1 wherein the first edible mixture is extruded to form the lengthened chew interior material to have a cylindrical shape, with at least one interior through opening.

5. The method as recited in claim 1 wherein the first edible mixture is extruded to form the lengthened chew interior material to have a spiral shaped cross section.

6. The method as recited in claim 1 wherein the second edible mixture is fresh meat mixed with glycerin and a starch.

7. The method as recited in claim 1, comprising comprising further drying the coated chew interior, following the coating.

8. The method of claim 1, wherein the second edible mixture comprises a syrup comprising:

animal meat forming 85% to 88% by weight of the second edible material;

glycerin forming 5% to 7% by weight of the second edible material; and

rice flour forming 5% to 8% by weight of the second edible material.

9. A method for manufacturing an edible dog chew comprising the steps of:

cooking a first edible mixture at a temperature between 100 and 110 degrees Celsius;

extruding the first edible mixture through a mold having an opening with a cylindrical outer shape and at least one mold projection projecting radially into the opening, the extruding taking place in a first direction to form a lengthened chew material;

cutting the lengthened chew material into defined lengths to form at least one cut chew material;

drying the cut chew material; and

wherein the first edible mixture is a starch-based mixture and has at least over 50 percent by weight of starch material, and the first edible mixture also includes an animal-based material, wherein the animal-based material is fresh beef, pork, chicken, duck or fish in a weight percentage of 10 to 15 percent of the first edible mixture.
