机译:速食方便米及其制造方法

摘要

PROBLEM TO BE SOLVED: To provide quick return instant rice restorable within 5 min with hot water and within 20 min with cold water, and also, whose taste, texture and appearance are equal to those of normal rice, and a method for producing the same.SOLUTION: Provided is a method for producing quick return instant rice comprising: a pressure digestion step S1 where non-dipped raw material rice is subjected to pressure digestion treatment to form a pregelatinized layer; a rice cooking step S2 where the rice grains subjected to the pressure digestion are rice-cooked with rice cooking water added with at least one kind of amylase and protease, and the rice grains are perfectly pregelatinized; a swelling step S3 where the rice grains after the rice cooking step are immersed into hot water of 60 to 70°C, and are swelled in such a manner that the water content in the rice grains reaches 70 to 80%; the primary drying step S4 where the swelled rice grains are dried at a relatively high temperature of 115 to 130°C for 20 to 30 min, and the water content is controlled to 20 to 25%; and the secondary drying step S5 where the rice grains after the primary drying step are dried at a relatively low temperature of 60 to 90°C for 50 to 60 min to control the water content to 10% or lower.SELECTED DRAWING: Figure 1
