Abstract: A manufacturing process for preparing packaged fast-cooking rice prepared by a process wherein raw material rice after being washed and soaked in water is heated to become gelatinized rice having a water absorptive property, and the resultant hot gelatinized rice is impregnated with an additive liquid so that swelled rice grains having non-sticking properties are produced. A predetermined amount of the produced rice is packed in an air evacuated package. The product rice can be cooked in an ordinary manner in a short time. By changing the additive liquid, rice containing a preservative or a seasoning can be obtained.
