From: Static-state particle fabrication via rapid vitrification of a thixotropic medium
a Static-state process in starch/water medium is devoid of any external force or internal particle coalescence during the solidification stage. Produced solid particles preserve the spherical shape of the emulsified droplets, and the particle size distribution is narrow with the mean particle diameter \(\bar{d}\) = 317 μm with the standard deviation \(\bar{s}\) = 22%. The particle size distribution is shown in the volume fraction, Q achieved from the image analysis, or in the cumulative mass, \({P}_{Q}\) achieved from the sieve analysis. b Dynamic-state process in starch/water medium mitigates internal particle coalescence but the continued shear force results in deformed particle shapes. c Dynamic-state process in water medium gives rise to both particle deformation and coalescence, resulting in particles with irregular shapes and a wide size distribution of \(\bar{s}\) = 65%.
