Abstract
Abstract A method is described for producing a dry pet food having a moisture content of less than 15 percent by weight. The dry pet food has a fibrous meat-like texture even though it contains a substantial amount of amylaceous ingredient. This texture is obtained by utilizing specific types of proteinaceous adhesives in conjunction with plasticizing agents and processing in a manner to form fibers.

Claim 1
Independent Claim
230 words
A method for the production of dry pet food containing less than 15 percent by weight moisture having a soft, elastic, meat-like texture and fibrous appearance comprising the steps of: A. blending a mixture of amylaceous ingredients, fat, a proteinaceous adhesive, and a plasticizing agent with a sufficient amount of water to produce a product having a moisture content of less than 15 percent by weight and an additional amount of process water; wherein said amylaceous ingredients are present in an amount from about 25 to about 50 percent by weight of the final product; said proteinaceous adhesive is present in an amount of from about 10 to about 25 percent by weight of the final product; said plasticizing agent is present in an amount of from about 5 to 25 percent by weight of the final product; B. heating said mixture at a temperature between 160°F. and 290°F. for a time sufficient to cook said ingredients and extruding the cooked mixture through a die to form an extrudate; and C. immediately cooling said extrudate by subjecting it to blasts of air; wherein said proteinaceous adhesive is at least one selected from the group consisting of a natural proteinaceous adhesive and a modified proteinaceous adhesive, said amylaceous ingredient is a foodstuff containing a preponderance of starch or starch-like material, and said plasticizing agent is a plasticizer suitable for food use.
