When the rice starch is hydrated, it loses the cohesion that holds the starch molecules of dry rice together after the hull of the grain is milled off or broken. The starches undergo a form of gelatinization. Cooked rice grains are swollen and soft, and will spoil more rapidly even if dehydrated again. They will harden and shrink if dried, but not to the original grain size.
When rice is pre-cooked to make "instant rice", it is steamed under high pressure that does not allow the grains to expand much while the starch is being hydrated.
