This study presents the interaction between konjac glucanmannan(KGM) and cationic surfactant dodecyl trimethylammonium chloride(DTAC) to provide theoretical guidance and prediction for the experimental design and application of this composite system. Dissipative particle dynamics(DPD) method was used to simulate the interaction between KGM and the cationic surfactant. Influences of concentration, temperature and shear process on the structure and properties of aggregates were mainly examined. The results revealed that the density peak increased with the increase of concentration of KGM. With increasing the temperature, density peak moved to the right and increased, and then decreased when the temperature rose to a certain value. The density peak moved to the right at the low shear rate while decreased at the high one. During simulation, the high viscosity related to the low diffusion rate, which made it difficult to form a large continuous phase.
