Why does pasta soften when boiled?

The dough of pasta is already a bit stiff, harder than other dough. Home-made pasta dough is softer than pastas sold on market shelves. Because the dough is made fresh and new (hardens as it dries). The pastas on the market shelves will remain on the shelf for a long period of time, so it is necessary to ensure that the pastas last longer. For this reason, pasta is packaged in a rigid structure with some methods. This method allows pasta to have more shelf life. When we put the pasta in the pot and water to boil it, the hardness of the pasta softens. The pasta slowly absorbs the water. This softening time can take 10-15 minutes. Because of the structure of the pasta, it starts to soften after boiling.
