Problems solved by technology

However, to the best of the inventors' knowledge, there is no known solution for obtaining low-density chews with high performance and high appeal, especially from formulations based on pregelatinized starch
In this regard, the expansion of pregelatinized starches is difficult to monitor and the final product shape is difficult to control
For example, the final product has a very rough surface and a rapidly growing structure that is not satisfactory

Embodiment 1

[0085] Based on the percentages shown in Table 1, based on 500 kg of dry blend, the ingredients were weighed and added to the batch mixer to blend for five minutes. Although pregelatinized corn flour is used, pregelatinized cereal flour can be used as an alternative or in addition.

[0086] The dry blend was metered into an Evolum EV53 (Clextral) twin-screw extruder together with the glycerol / phosphoric acid mixture and water in the proportions shown in Table 1, and was heated at 115 kg / h, a pressure of 64 bar and a temperature of 117°C. Form a plastic dough. Phosphoric acid is not required, but may be added to provide an additional preservative effect.

[0087] Table 1

[0088]

[0089] The extruder was equipped with 10 barrel segments with an L / D ratio of 40. To achieve moderate shear, one reversing screw element was inserted at the end of the fourth barrel, and two such elements were inserted at the end of the fifth barrel. The screw rotated at 140 rpm and the dry ...

Embodiment 2

[0092] Example 1 was repeated with the following exceptions. 0.5% sodium bicarbonate was added to the dry blend shown in Table 1 and the pregelatinized corn flour was thus reduced to 83.08%. The maximum pressure and SME are 67 bar and 447KJ / Kg, respectively. The plastic dough is then passed through Image 6 The die system with opening shown was extruded and cut into 120 mm long pieces with a density of 0.74 Kg / L and an expanded porous internal structure ( figure 2 ). Dies with dovetail designs were found ( Image 6 ) avoids a blistered rough exterior surface and produces an acceptably smooth exterior surface. In addition, a single tubular insert is inserted within the mold opening to form a hollow in the product block ( figure 2 ).

Embodiment 3

[0094] Example 2 was repeated with the following exceptions. 1% sodium bicarbonate was added to the dry blend shown in Table 1, and the pregelatinized corn flour was thus reduced to 82.58%. The maximum pressure and SME are 67 bar and 452KJ / Kg, respectively. The plastic dough is then passed through Image 6 The die system with opening shown was extruded and cut into 120 mm long pieces with a density of 0.68 Kg / L and an expanded porous internal structure ( image 3 ). Dies with dovetail designs were found ( Image 6 ) avoids a blistered rough exterior surface and produces an acceptably smooth exterior surface. In addition, a single tubular insert is inserted within the mold opening to form a hollow in the product block ( image 3 ).

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

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 083,567, filed November 24, 2014, the disclosure of which is incorporated herein by reference. Background technique [0003] The present disclosure generally relates to low density edible chews having a porous matrix that provide sufficient bite depth to facilitate mechanical tooth cleaning, and also to methods of making such chews. More specifically, the present disclosure relates to edible chews having a low density and a smooth outer surface, which can be achieved by modifying the extrusion process. [0004] Animal chew toys are designed to entertain animals, distract animals from boredom, prevent destructive animal chewing behavior, and provide an outlet for an animal's innate chewing instinct. Generally, animal chew toys are made of plastic or other materials that cannot be eaten by animals. Animals usually get tired of inedible animal chew toys...
