Abstract: A method for testing the ingredients of fabricated snack products includes the steps of; producing snack product test pieces using a test ingredient; evaluating certain characteristics of the test pieces; and then using this information to predict the characteristics of a fabricated snack product containing the test ingredient. Initially, a dough containing the test ingredient is mixed under controlled conditions. A quantity of the dough is extruded using an extrusion apparatus adapted to extrude the dough at a uniform rate regardless of the dough's consistency. The extruded dough is then cut into dough pieces having a uniform length, wall thickness and density. Next, the dough pieces are cooked at a predetermined temperature for a predetermined time to form the snack product test pieces. Characteristics of the test pieces are determined and analyzed as a predictor of similar characteristics in a fabricated snack product containing the test ingredient.
