Abstract: The present invention relates to a method for producing a pet chew product by a single injection molding cycle, comprising the steps of providing a thermoplastic starch mixture; converting said mixture into a thermoplastic starch-based melt; injecting the resulting thermoplastic melt comprising said optional blowing agent in a mould cavity while partially opening the mould during melt injection; allowing the thermoplastic melt in contact with the mould cavity wall to at least partially cool and set thereby forming the outer skin of a first density or hardness; partially opening the mould during melt cooling to allow gas expansion in the non-cooled core of the injected thermoplastic melt and formation of a foamed core of a second density or hardness; allowing the melt to cool and set, and ejecting the pet chew product from the mould cavity.

Abstract: The present invention relates to a pet chew product comprising a skin of a first thermoplastic starch-based material enveloping a core of a second thermoplastic starch-based material, wherein the first and second thermoplastic starch-based materials may be the same or different, the core having a density or hardness lower than the skin, wherein the pet chew product is produced under constrained cooling conditions.

Abstract: The invention relates to a flexible, non cellular pet chew comprising: a) 51-90 wt % based on the dry solid weight of the mixture of a (thermoplastic) cereal flour, wherein the cereal flour has a protein content below 10 wt. %, b) 5 to 30 wt. %, based on the dry solid weight of the mixture of a plasticizer, and c) 1 to 35 wt. %, based on the dry solid weight of the mixture of a fibrous material.

Abstract: The invention relates to a pet's chew prepared from natural materials of renewable sources. The chew is both edible and biodegradable, and furthermore has excellent mechanical properties giving it a long lasting time, even if used for strong animals such as large dogs.

Abstract: The invention relates to a pet's chew prepared from natural materials of renewable sources. The chew is both edible and biodegradable, and is furthermore both tough, flexible and dimensionally stable, and maintains these characteristics over a much longer time than chew known in the art.
