2.5. Microstructure of the cooked KGM noodles
The raw and cooked noodles were cut transversally into cubes, immediately frozen at −80 °C and lyophilized. Freeze-dried samples were mounted on a silver specimen holder and coated with gold for 60 s. Microstructure of cross-section was observed by a Scanning Electron Microscope (HITACHI, Japan) at a voltage of 15.0 kV with micrographs taken at magnification of 600×.
