Cooking recipe books may recommend adding salt when boiling pasta.
At this time, it is often stated that about 0.5% salt is usually added to boiled water.
(Generally, the preferred salt concentration in cooking is 0.8% to 1.0%)
The reason for this is
①Season the pasta.
②The pasta is finished in an elastic state. (Prevents the outflow of salt added to dried noodles)
③Suppresses gelatinization of starch reduces exudation and reduces sticking of noodles.
A common mistake is to raise the boiling point of water.
Because even if you add salt, the boiling point does not rise much.
If you add too much salt and it becomes salty, you should wash the boiled pasta noodles with hot water.
