The pressure-nonboiling rice-cooking technology was put forward based on the comparison with atmosphere cooking, pressure-boiling cooking and optimization of the pressure-nonboiling rice-cooking technology were studied. Results indicate the optimal parameters of the pressure-nonboiling rice-cooking technology are as follows: soaking rice under 40 C for 10 minutes, exhausting cool air when heated to 98℃-100℃, and then keeping pressure at 40kPa for 6 minutes. The cooked rice product by optimized pressure-nonb...
