(Rice plays an important role in the national diet，and the loss of nutrients in natural rice is severe after shelling and milling.Extruded rice was prepared by extrusion technology with natural rice as raw material to add nutritional strengthening agent.It can compensate for the loss of nutrients in natural rice and alleviate the health problems caused by the lack of certain trace elements.The research progress related to extruded rice locally and abroad was reviewed，including its production process and the effect of the process on the quality characteristics of the crop，thereby providing a reference for the innovative work of extruded rice production.)
