Embodiment 1

[0043] Table 1 shows resin formulations containing 8% hydrolyzed wheat gluten (HWG 2009, produced by MGP Ingredients, Inc.). Resin pellets were produced using an 85 mm twin-screw extruder (TX-85 manufactured by Wenger) with a hot face diecutter. The powder-liquid mixture in the extruder is mixed at a melting temperature not exceeding 95°C to avoid thermal denaturation of proteins. After the die face cuts the pellets, the resin pellets are air conveyed to a cooler and packed.

[0044] Examined after 4 months, the presence of 8% hydrolyzed wheat gluten helped to increase the shelf life of the resin pellets. The molded article exhibited the same appearance and physical properties as those produced immediately after the resin was prepared.

Embodiment 2

[0048] Table 2 shows resin formulations containing 5% hydrolyzed wheat gluten-emulsifier complex. By adding Panodan TM SDK emulsifier (supplied by Danisco) was added to the HWG 2009 protein dispersion to prepare the hydrolyzed wheat gluten-emulsifier complex and spray dried. The hydrolyzed protein-emulsifier complex contained 25% Panodan in the spray-dried product TM SDK (emulsifier).

[0049] Resin pellets were produced using an 85 mm twin-screw extruder (TX-85 manufactured by Wenger) with a hot face die cutter. The powder-fluid mixture in the extruder is mixed at a melting temperature not exceeding 95°C to avoid thermal denaturation of proteins. After the die face cuts the pellets, the resin pellets are air conveyed to a cooler and packed.

[0050] Examined after 5 months, the presence of 5% hydrolyzed wheat gluten-emulsifier complex helped to increase the shelf life of the resin particles. The molded article exhibited the same appearance and physical properties as tho...

Embodiment 3

[0054] Table 3 shows formulations containing 3.5% liver digest product (OptimizorTM CHX-base, produced by Applied Food Biotechnology, Inc.). CHX-Base liver digest is a form of a complex of hydrolyzed protein, hydrolyzed protein derivatives, and an emulsifier, wherein the protein is poultry liver and the emulsifier is hydrolyzed animal fat. The hydrolyzed protein derivative is the reaction product of hydrolyzed protein and maltodextrin to enhance flavor. Resin pellets were produced using an 85 mm twin-screw extruder (TX-85 manufactured by Wenger) with a hot face die cutter. The powder-fluid mixture in the extruder is mixed at a melting temperature not exceeding 95°C to avoid thermal denaturation of proteins. After the die face cuts the pellets, the resin pellets are air conveyed to a cooler and packed.

[0055] Checked after 5 months, the 3.5% CHX-Base liver digest helped improve the shelf life of the resin pellets. The molded article exhibited the same appearance and physic...

Abstract

Shelf stabilizing agents including hydrolyzed protein, hydrolyzed protein derivatives, and hydrolyzed protein-emulsifier complexes improve the shelf life of a pelletized grain protein-based resin formulation. The pellets may be prepared well in advance of further processing, such as by injection molding and extrusion, which provides shaped articles of the edible or biodegradable variety.

Description

field of invention [0001] The present invention broadly relates to cereal protein formulations with improved shelf life. More specifically, the cereal protein resin formulation can be made into pellet form prior to final product processing, and then these pellets can be converted into shaped articles by, for example, injection molding, extrusion, or other molding equipment. The shelf life of the protein resin formulations is increased by adding storage stabilizers such as hydrolyzed protein, hydrolyzed protein derivatives, and hydrolyzed protein / hydrolyzed protein derivative-emulsifier complexes. Articles made from such resins can be petchew treats, edible products, and biodegradable products. Background of the invention [0002] Petroleum-based synthetic resins find widespread use in the manufacture of a variety of products. Grain-based resins have also been used. For example, US Patent No. 5,665,152 to Bassi et al., which is incorporated herein by reference, describes m...
