The invention provides nutritional rice type particles for improving intestinal canal, which are processed by using grain powder, fructo-oligosaccharide and dietary fiber as raw materials. The nutritional rice type particles is added with the special function of improving the intestinal canal on the basis of the original nutrient of grains, so that not only can the nutritional ingredients desired by a human body be improved, but also intestinal canal of the human body can be effectively improved, and the micro-ecological health of the human body can be adjusted. The finished product of the nutritional rice type particles is slightly different from original rice in appearance, taste and flavor. The invention further provides a processing method of the nutritional rice type particles for improving the intestinal canal. The processing method of the nutritional rice type particles for improving the intestinal canal comprises the following steps: smashing the grains, blending with the fructo-oligosaccharide and the dietary fiber, tempering and gelatinizing, squeezing and cutting, drying, screening and the like. The processing method has the advantages of simple technological process, strong operability, high automation degree, high production efficiency and strong product simulation, and can produce the nutritional rice type particles with different colors and different forms according to the characteristics of polished round-grained rice, early indica rice, late indica rice, black rice, millet and the like.
