The invention relates to a preparation process of convenient rice, which comprises the following operational steps: A, washing rice; B, soaking the rice for the fist time; C, stewing the rice for the first time; D, soaking the rice the second time; E, stewing the rice for the second time; F, dispersing the rice; G, drying the rice to obtain finished products; and H, packaging the finished products, wherein soaking liquid contains 0.2 to 0.6 percent of citric acid, 0.1 to 0.3 percent of beta-cyclodextrin and 0.1 to 0.3 percent of sucrose fatty acid ester. The soaking liquid improves the edible quality of the convenient rice and strengthens the anti-retrogradation performance of the convenient rice while shortening the rehydration time of the convenient rice, so that the edible quality of the convenient rice is the same as that of fresh rice; and the gelatinization degree of the rice is improved by adopting the process of the two-time soaking and two-time stewing, so that the rehydration time of the convenient rice is shortened to 8 minutes. The preparation process has the advantages of reasonable process design, low equipment requirement, conveniently-eaten product, long quality guarantee period and good edible quality, and has the high popularization and use values.
