tKonjac glucomannan (KGM)/ethyl cellulose (EC) could form a stable homogeneous emulsion with appro-priate mixing formula. This study aimed to investigate the stable mechanism of KGM/EC emulsion atdifferent mixing ratio through its rheological properties, and droplet size and morphology changes withup to 6 days storage time. Though emulsions samples with high KGM content had larger droplet size andworse uniformity at the fresh stage, they appeared to be more stable and droplets growth rate were slowduring storage. Aggregation and morphology of droplets could be observed under confocal microscopy.Shear-thinning behavior were found in mixed emulsions, and mainly accredited to the KGM component.The effect of temperature on viscosities of the emulsions was well-described by Arrhenius equation.Increased KGM content led to larger storage modulus (G) and loss modulus (G), and the difference incross-over point of Gand Gimplied changes in microstructures of the emulsions.
