Food Structure

Abstract

Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Instron measurements were used to evaluate the effects of an Achromobacter iophagus culture {BC) and splenic pulp (SP) treatments one structural and textural properties of flaked and restructured beef steaks. Both treatments improved the textural character is tics of the product when conditioned at 35°C . Electron microscopy studies revealed that the bacterial culture treatment caused a greater effect than SP on the connective tissue elements, with a degradation of the endomysial sheath and sarcolemma. Treatment with splenic pulp produced an overall excessive disruption a t the Z-lines with little definition of the A-bands.
