Cryo-scanning electron microscopy (Cryo-SEM)
First of all the microstructure of raw pork loin was characterized.
Fig. 5A shows a cross section of the raw pork loin, where cells
are surrounded by the membrane or sarcolemma (Fig. 5A, S). These
cells are interconnected by endomysial connective tissue (Fig. 5A,
EC), which keeps the muscle fibers tightly attached. In addition,
the myofibrils inside the muscle cell can be observed, which are
fundamental components of the cell’s contractile apparatus
(Fig. 5A, M)
