Abstract: Starch plays a very important role in the processing of extruded aquatic feed. It can not only enhance the stickiness of mash feed, but also play a dual role of expansion and adhesion in extruded feed. Due to the different granular structure of starch from different sources, the effects on the processing and quality of extruded aquatic feed are also different. This paper reviewed the research progress on the relationship between the basic characteristics of different starch sources and the processing and quality characteristics of extruded aquatic feed. The differences of starch components, structure, gelatinization properties, rheological properties and thermodynamic properties of different starch sources were analysed. The effects of different starch sources on the quality characteristics of extruded aquatic feed were compared. In addition, the problems and development directions of different starch sources in the research process were prospected.
