Production method of fresh-keeping rice cake

The invention relates to the technical field of rice cake production, and discloses a fresh-keeping rice cake production method, which comprises: S1, soaking polished round-grained rice in warm water to swell; s2, adding polished round-grained rice, a first preservative solution and water into a pulping machine, and crushing to obtain rice milk; s3, performing vacuum dehydration treatment on the rice milk, and adding fruit and vegetable juice and a plant extract to obtain mixed rice flour; s4, cooking the mixed rice flour; cutting the rice cakes into rice cake blocks with uniform sizes; and S5, soaking the rice cake blocks in a second preservative solution, draining water, performing vacuum packaging, and performing high-temperature sterilization. The prepared rice cake is slow in microorganism breeding rate and long in shelf life in the storage process; in the shelf life, the water loss rate is low, the hardness increase is small, the viscoelasticity of the rice cake can be guaranteed, and the rice cake can
