2.2.5. Structure of the dried rice noodle
2.2.5.1. Scanning electron microscopy (SEM)
Each dried rice noodle sample was mounted on a stub and both the rough and smooth surfaces were observed. Cross-sections were examined by fracturing the dried rice noodles and mounting on a stub. The cross-sectioned surface was observed from the top view. All dried rice noodles were observed under a scanning electron microscope (INSPECT S50, FEI, Netherland) at an accelerating voltage of 10 kV and a working distance of 5 mm in high vacuum mode. Magnification of 100× was applied for observation of both surfaces and magnification of 500× was applied for the cross-section.
