Twenty formulations for turkey frankfurters were evaluated using 2.379 to 6.621% modified corn starch and 20.93 to 35.07% water. Cooked frankfurters were evaluated by a descriptive panel. Internal color, compression, percentages fat and moisture, purge loss, and pH were measured. Levels of starch and water affected percentages of fat and moisture of the batter. Frankfurters with low levels of starch were more yellow, firmer, and not as cohesive as those with high levels. Frankfurters with high levels of water were softer, lighter in color, and juicier than those with less water. Increased levels of starch and water maximized organ meat/metallic flavor. For optimal sensory and physical attributes, the predicted levels should be starch 2.3% and added water 33.6%.attributes and physical characteristics for turkey frankfurters with reduced fat.
MATERIALS & METHODS
RESPONSE SURFACE METHODOLOGY(RSM) was used to determine the effect of 20 treatment combinations of selected levels (Table 1) of starch and water on turkey frankfurters. The frankfurters were processed in random treatment order over a 2-day period. Turkey frankfurters formulated with 20% added water (based on weight of meat) with no added starch were produced on each production day and served as the "standard."To determine the levels of starch and water for frankfurter formulations that produced optimum sensory attributes and physical characteristics, an augmented central composite Box-Wilson response surface designThe authors are affiliated with the
