Extruded rice noodles are made from rice as raw material, ground and blended to a certain moisture content, extruded and matured, and dried. The traditional production process of rice noodles is laborious and time-consuming, which lead to uneven product quality during the multi-step rice noodle production process. By comparison, extrusion technology is a food processing technique that integrates mixing, heating, sterilization, and shaping. Applying extrusion technology to rice noodle processing has the advantages of less loss of nutrients, fewer opportunities for microbial contamination, shorter production time, higher production efficiency, and easier operation. Therefore, in the production of rice noodle processing industry in China, automated mechanical processing is gradually replacing traditional manual workshops. The quality of extruded rice noodles is mainly affected by the raw materials, processing technology, and extrusion parameters during the production process of extruded rice noodles. Therefore, this paper elaborated on the processing technology and forming mechanism of extruded rice noodles, summarized the influence of raw materials and extrusion parameters on the quality of extruded rice noodles, in order to provide theoretical basis for the control of the processing technology and key points of extruded rice noodles.
