摘要

PROBLEM TO BE SOLVED: To provide a method for producing instant dry rice, and instant dry rice.;SOLUTION: In the method for producing instant dry rice, moisture inside rice grains is evaporated by subjecting raw material rice to a dry heat treatment on the way of a pregelatinization step and gaps are formed in the internal tissue of the rice grains in producing the instant dry rice by pregelatinizing the raw material rice in the pregelatinization step and drying the pregelatinized raw material rice. The instant dry rice produced in this method has such characteristics that: a. the gaps are formed in the internal tissue of rice grains by the heat treatment during the step; b. the specific volume is not more than 2 (ml/g); and c. the stress (g/cm²) in five minutes after injection of hot water is at least 70% of the stress of boiled rice using the same raw-material rice. The high-quality instant dry rice having both convenience such as to be restored with hot water in five minutes and an excellent texture (stress value) equal to the texture (stress value) of boiled rice can be provided.;COPYRIGHT: (C)2012,JPO&INPIT
