Abstract
A formulation and process to produce a pet food or treat that has been reshaped to various sizes and shapes such as strips, pellets, sheets, etc., from the addition of a number of raw ingredients which were mixed and heated and fused together to form a continuous matrix which remains flexible and non-brittle at low moistures of 20-40%, water activity of 0.30-0.65, and having a low glass transition compound as the major adhesive component of the matrix, thus being stable at minimum or no packaging atmosphere at room temperature is herein described. The process is carried out in a twin-screw, self-wiping, corotating and intermeshing extruder.
Claims5
A method for producing a semi-moist pet food or treat product having a flexible or jerky-like characteristic with a chewy or leathery texture consisting essentially of carrying out in a twin-screw, self-wiping, co-rotating and intermeshing extruder the steps of:
- (a) kneading a mixture comprising a filler, a hydrocolloid and a liquid binder having a glass transition temperature of less than about +10.degree. C. at a temperature of about 175.degree. to 250.degree. F.;
- (b) venting off under reduced pressure water and volatiles;
- (c) cooling the dough-like mixture to about 0.degree. to 150.degree. F., and
- (d) conveying the product through a die onto a conveyor belt for cutting and packaging;
- wherein the product has a moisture content of about 20 to 40%;
- a water activity (Aw) of about 0.35-0.65, and a glass transition temperature of less than about +18.degree. C.
