Effect of Auger- and Press-Type Mechanical Deboning Machines on Selected Characteristics of Mechanically Deboned Poultry

Selected chemical, functional, textural, and sensory properties were evaluated for mechanically deboned poultry (MDP) prepared from three auger-type (Paoli, Beehive, and Yieldmaster) and one press-type (Protecon) mechanical deboners. Protecon MDP, prepared without a preliminary grinding of the in-going raw material, contained slightly larger intact muscle fibers than MDP from the auger-type machines. Although variation occurred among the four meats, no significant differences (P7>0.05) were observed in their composition. Differences existed in the emulsifying capacity, emulsion stability, and waterholding capacity of the meats; however, all were successfully used in the preparation of acceptable frankfurters. Frankfurters prepared from Protecon or Beehive MDP were generally firmer, as determined by shear tests and sensory evaluations.
