The noodle formula consisted of 500 g of flour and 175 mL of
distilled water. During the processing, 10 g of salt were first dissolved
in water and then hydrated. The dough was formed using
a small vacuum mixer (Model ZHM5-S, Zhengzhou, Henan, China)
under various programmed parameters. The prepared dough was
placed to rest in a plastic bag for 20 min. Then, the dough crumbles
were passed through a small noodle machine (Model JMD-168/
140, Beijing, China) for 6–8 times with the roller gap reduced gradually,
to get dough sheets. The dimensions of the resultant noodle
strands were 1 mm in width and 0.9 mm in thickness.
