Abstract

Edible chews for pets have a low density (e.g. about 1.0 Kg / L or less) and a smooth exterior surface. One method by which the low density and the smooth exterior surface can be achieved uses a modified extrusion die to increase shear and restrict surface bubbles. Another method by which the low density and the smooth exterior surface can be achieved uses an extruder screw with a modified profile that holds a dough longer therein to create a whipping effect resulting in more bubble nucleation sites and hence a more uniform cellular matrix. The puffed (expanded) product was experimentally tested and provided better dental cleaning scores than a current unexpanded similarly formulated commercial dental product.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 62 / 083,567 filed Nov. 24, 2014, the disclosure of which is incorporated herein by this reference.BACKGROUND

[0002] The present disclosure relates generally to low density edible chews having a cellular matrix that provides sufficient bite depth to facilitate mechanical teeth cleaning and further relates to methods of making such chews. More specifically, the present disclosure is directed to edible chews having a low density and a smooth exterior surface that can be achieved by modifying an extrusion process.

[0003] Animal chew toys are designed to entertain the animal, combat animal boredom, prevent destructive animal chewing behavior, and provide an outlet for an animal's innate chewing instinct. Generally, animal chew toys are made from plastic or other material that cannot be eaten by the animal. Animals typically tire of non-edible animal chew toys after a short period ...
