Question

why does bread become soft when heated during cooking ?​

Answer 1

Answer:

In microwave heating, the starch of the bread is re-gelatinised. That is to say, the starch molecules bind to water molecules, which sort of dissolve or plasticise the starch, making the texture of the bread softer overall

Answer 2

Answer:

when we put bread in microwave it causes the remaining water in bread to heat up and warm water causes some of the hardened starch to regelitanized which makes bread softer again
